 So today, I'm going to be making some capacitor kits for different monitors I've got coming up. And I thought maybe it would be beneficial for me to do a follow-up video on how to make capacitor kits. And I could show you a little bit more on what the exact details are when you see a couple of symbols or letters written on the side of a capacitor and also help you pick a better capacitor because, honestly, the recommendations that you're going to find for replacement from your service manual is going to be very vague in general. And there's going to be a lot of different choices for you. And it can be overwhelming. So I thought I'd just show you and maybe make it a little bit easier and narrow down some of the choices that you might have for replacement capacitors. And in the background here, I've got a couple of capacitors. This is a normal, high-quality, electrolytic capacitor. It's aluminum. And it's radio-ledded. And so you've got a negative side on here, which is in the white. And then the rest of the capacitor is dark, so that other leg is the positive. And then you'll notice that it has a capacitance rating on the side as well as a voltage rating. So this one happens to be 4.7 microfarads. And then we've got 250 volts. So that's just an example of the majority of the capacitors you're going to run into that you're going to need to change. Other capacitors are most likely not going to need to be changed. So the next thing we're going to jump over here to is a copy of a service manual for a PVM that has a lot of electrolytic capacitors in it. And we're going to go through now and make the kit for this. But just to show you, you can get in the back of these service manuals. This is on about the 104th page of that manual. And it does list here our G board, which is our power supply unit for this particular PVM. And then it's got a parts list here for everything that is a capacitor first off. So it's in alphabetical order, so it starts with capacitor. If we look through these capacitor listings, there are quite a few on this board. But the ones we're going to only concentrate on are the ones that say ELECT or electrolytic. These other types, these film and ceramics, they don't generally go bad. And we don't need to replace them. So today we're going to go through and first look at some of these electrolytic capacitors. And so if you're making a kit, the first thing you'll notice is you want to go down here. For example, for your G board, and the first one you'll run into that's electrolytic is C616. So you can record that. And it will tell you a microfarad capacity, which is 47, and then a tolerance, which is 20%. And then it'll give you a voltage rating for the capacitor. And all that is written on the side of the capacitor, like I showed you in the previous picture. But there's a lot more information on a capacitor that's going to determine a lot of whether, you know, how long it's going to be lasting and how well it performs in the machine. So we're going to talk about some other things you can look for for a replacement capacitor, besides just the simple capacitance, tolerance, and voltage rating. Some of the other things you can consider would be, first off, is the size of the capacitor. So this is a backside of our G board, which has these capacitors that we just saw. So this is B616 up at the top that you can't see, but you could see 618 has been removed. And so is 619. And then if you look at this side, you'll see this one has the positive mark. So this is the positive end of the capacitor. And then there's no marking, or you'll notice the half crescent moon that is marking the negative side on there. So that's just one more thing you note. So if you do remove it, you can tell which way they go back in place. But also, the next thing I mentioned you might want to consider would be the size of the capacitor. Most capacitors are going to come in a standard size. But occasionally you'll run into ones that may need to be a thinner and have a smaller distance between the two leads. So what you can do is you can go in and you can measure the distance on the board between these two leads. Because when you buy a capacitor, and I'll show you that coming up, one of the statistics that will give you is the size of the capacitor. And just getting a different size capacitor that's not perfect, that's not going to really impact the performance of the machine. And it's perfectly safe, honestly, most of the times. It's just it's not as easy to replace. And it doesn't fit in as cleanly sometimes if you don't get the exact size. So that's one other thing to consider is that size on there. And then another thing to consider is going to be our temperature rating on the capacitor. They'll have a minimum rating generally in CRTs of 85 degrees Celsius. But it does go up from there and that heat is going to impact our last thing that we're going to be really concentrated on. And that is our lifespan. So let's go now and go over to an order sheet. And I've actually been working with Mauser. That's the distributor I work with most of the time. And so you can go in and use any other distributor such as Digi-Key or any other major parts distributor that you may like yourself. But again, I've always used Mauser. And that's the one I'm going to show you through today. Don't feel obligated though to use them to get things like capacitors and other parts. So for example, I'm here. Let's say I want to go in and look at some capacitors. Well, one of the first things I'm going to do is I'm going to type in aluminum electrolytic capacitor. And I even like to add radial. And that's just going to limit our number of capacitors we're going to get back to replace because we don't want to see a lot of other types of capacitors. And so what we're going to do is we're going to go in here now and we'll try to order replacement from our cap kit over here. Let's pick capacitor 618, which is a 10 microfarad, 50 volt capacitor. So if we go over here, what I'm going to do is I'm going to go after my radial, I'm going to type in 10 microfarad and you can type that by typing in UF and then you hit a space and then 50 volts. And then I'll hit a search and we'll see what comes up. All right, so our results have pulled up. Let's see if I can get this over in the screen a little bit more, but our results have come back with almost 500 different capacitors for options for us. Let me check if I could, there we go, scale that down a little bit, get that on to the screen and then we'll kind of go from there. So we've got 470 choices. What I'd like to do is I'd like to select one that's in stock. And today I'm going to look at my favorite brand. Now there are a lot of great brands. Most of these listed on here are really top notch that you have even a choice of, but I've primarily been using Nishicon. So that's the one that I'm going to select and then I'm going to hit apply to those filters. And then it's going to give me even more choices. And that way now we can talk about other things that we might want to consider when we're purchasing a capacitor because we still have almost 100, we have 98 choices to choose from. So we can again narrow it down a little bit on here. And if we look at our stuff we want to narrow it down by, you can do it by the spacing, but we're not concerned about that as much. We're definitely going to select 105 degrees Celsius and then we're going to select 50 volts just to make sure we only get 50 volts back. And then we're going to leave the rest of them blank so we can talk about some other things. So we'll apply those filters and see how many it gives us back that are in stock. So that takes it down to 26. This is going to be much more helpful. Now we can go down here and we can look at some Nishicon's products that came back that are higher tolerance and have different, they're all going to be a little bit different characteristics from this point on, but it does give us a lot lower number to choose from. So next thing you're going to run into are some interesting terms that you'll see on a lot of these. Most of the ones you're going to find nowadays are going to say this. They're going to say low impedance electrolytic capacitor, which that is fine to use in CRT replacement and repair. And so you're going to have, it's going to either list that or it's going to list a general use electrolytic capacitor. Either one of those is going to be fine for your CRT repair. Most of the time, the low impedance electrolytic capacitors are a little bit higher quality and last longer. So this meets all those specifications that we put in here where it's definitely radial. It's got a luminal electrolytic. It's 50 volts DC. The capacitance is 10 microfarads. 105 degrees Celsius temperature rating. And then here's our size if that's important to us. And then this is one of the more important things we're looking at is our lifespan. Now this 5,000 hours, that's rated at 5,000 hours if it's at 105 degrees Celsius constantly, which most of the time these capacitors aren't going to be running that high of a heat. So their real lifespan can sometimes be as much as three times that number up to 10 times that number if it's not currently under a high heat load. So just keep that in mind. That's why I'm gonna shoot for 5,000 hours on the majority of my replacement capacitors. It's gonna be 5,000 hours or more for replacement capacitor. Now one other thing you'll notice here is there are some letters in front of these capacitors. One says by the manufacturer, you've got a UH and some other UHE. And then you'll notice it on some other capacitors. For example, this one right here says UHD. This is another different valued capacitor, but it is by Nishikon. And those will determine again the product line that you're looking at for a specific capacitor. So if we go down here and look at Nishikon's specific product designation for these capacitors, it can help us actually narrow down to where we can eliminate a lot of these capacitors that we might be seeing that are coming back as in stock is not being really suitable for what we're gonna do. And for example, if we look here, these UBY and UXY, neither of those are really gonna be the greatest for our CRT repair. And I'll pull up kind of the explanation on here. Why? First off, their life cycles are featured to be up to about 3,000 hours. And it does sound good because it's got an anti-vibration structure. However, this is gonna be a capacitor that's used to a lot of load, heavy-duty services, and where you've got a lot of vibrations and vitality is required or heavy-duty services are required. So it's not that it's not, and it would be probably work fine, but again, it's built to do things in a car that are probably gonna be a little bit more stressful in the capacitor than we need to get for. So those two, I don't recommend too much, but if you look down here at the other brands that they have or the other series, Nishikon, that they've come out with, we're gonna look specifically at the ULD series and the UHW series, which if we go in here, it does give us the capacitance range. So that's important to note when you're looking for a capacitor and then it tells us the life expectancy. But the reason I'm highlighting these is these are gonna, when you go search through the capacitors, you're gonna run into, if you don't do the things that I talked to you about, about changing the temperature filters, you're gonna find a lot of lower quality ones that are only 85 degree rated and their life span's not gonna be as big, but these higher-end quality capacitors do have a higher life span and also tend to start at that 105 degree Celsius range. So there's just some more information on this one, but the reason I bring this one up, this is ideal for power supplies. It says for LED lighting, which is the modern use for a lot of these, but even they're not gonna have a modern use listed as being a capacitor designed specifically for CRTs anymore. But that's one to consider and then the UHW is the same thing. It just has a different voltage range and you can tell down here that these are really high quality. Again, this one has up to 10,000 hours at 105 degree Celsius, which is just an incredibly durable capacitor, way more durable than most of the ones that you'll be removing and replacing in your current electronic device. And so when you go through here and you found a cap, for example, this capacitor right here, it is many sized. So that is the one drawback that I would be considered is I would definitely go then and check to make sure that this size would fit in to my spot back here on my picture. I would wanna make sure and take a little measuring device and measure the distance between here and make sure that that is not a huge problem before I place an order for this mini size one. Because other than that, it is pretty much perfect for the application here. And again, the real issue is you're just gonna have a lack of information. Now, if you do have a service manual and it says specifically low impedance or it gives you an even an ESR rating, there is a formula to calculate to figure out what the impedance needs to be or impedance needs to be on the exact capacitor for like the ripple current, which is listed on here and things like that. But again, that's only if it's specified in the manual. Otherwise, you can really use either the low impedance or the general use capacitors. So anyway, once again, you pick your capacitor, you can go in here and then you just add the number that you want and hit buy and it'll go in. This company will put it in a shopping cart nicely for you. And if you create a profile, you can even save your builds that you build on here. And so that's very handy, but that's pretty much how to go through and determine the difference. Now, you can also use, these sites will generally have a lot of good information. So if you want to use a different type of capacitor, they have all this stuff. And then if you even want to do a deeper dive, there is the manufacturer's data sheet here available directly on this webpage for each one of these parts. And it gives you even more information on the exact readouts for each capacitor. And then again, like right here, it tells you the series name. So we talked about the UH series. So anyway, that's just a look at the capacitors. And if you guys have any more questions about capacitors, please feel free to leave me a comment below. But I hope this helps you kind of understand a little bit more. Just remember, you're gonna wanna look for, again, high heat tolerance and the right, of course, capacitance and voltage rating and then make sure it has a 20% tolerance or whatever tolerance is referred to in your manual. And then just make sure it fits in there and you'll be good to go. And like I say, if you use these high end capacitors, it will last 10,000 hours of stress time, which is more like 20,000 hours of actual use time on, for example, a CRT. Thanks again for watching today, everybody. I'll see you guys next time with some more retro content.
