 The great search brought to you by a fruit engine key lady user powers of engineering to show you were too fine And how to find the part that you're looking for on digikey.com lady Anna. What is a great search this week? Okay? Well, let's go to the overhead So this week Oh, it's actually look can you show the photos? We went to which one the botanical gardens and we celebrated pink And we thought we would Take some photos. It's our nice pink PCB. I just want to show I love to show these photos again And this inspired me today because you were asking like oh, you know, we have these pink PCBs on the overhead This is the pink KB 2040 PCB with the custom pink solder mask from our PCB house. We use I Know PCB way will do prototypes second you can do it Okay You can get protection PCB way, but our PCB house. We've got these custom pink PCBs And you were like, oh, you know, can we change this green LED to be like pink or purple because I you know would look a Lot better than just green right if you wanted to go with the pink aesthetic Which we do love here at a fruit and I thought I was an excuse to show how to get You know custom like weird colored LEDs on digikey and also a lot of people always like oh There's so many elite on digikey and it's like I just want to like Get it to a reasonable amount and then I can pick the color and then how to use that the nanometer selector Also to determine what color you're going to get so even though I didn't end up finding pink exactly I did find something very close. So let's go to the computer and And Let's go to digikey. Okay. So what we're looking for is an indicator LED There's illumination LEDs and those are like really bright like white LEDs for back lights indicators are like what we know You saw on that PCB. It's a little little lights Usually a 402 to 1206 size You know 20 to maybe 200 milli candela just enough to indicate to a person that something is working. We're not working So we want discreet, which means individual because there's One that are in a raise and there's one that are like, you know pilot light the panel indicators We want individual ones and then I'm going to show you how to pair it down because I particularly want pink But I also was I ended up not being able to find pink. So it's like what was the closest thing I could get So there's a there's a lot of LEDs and I know it can be very tough to find LEDs So the first thing I'll do is I'm just gonna look only for the active ones. It's a quick way of Pairing down about half of them because you know, we don't want ones that are discontinued or unavailable There's also the configuration. So there's some of these are Dual color like they're red and green and you can turn on both to make them amber So they're bi-directional or they have common anode or common cathode If you see common anode or common cathode that means it has to have more than one LED in it Otherwise, it would be a common to it. So what we want is independent Standard and dash, which means like okay didn't get categorized with with that So that'll that'll maybe get rid of a couple thousand more. We don't want like an individual LED The next thing we're gonna look at is I only want surface mount and I only want surface mount Pointing up. So I'm gonna just make sure that I've deselected all the two whole ones And then I'll cut it down by half again You see just you're cutting it down by half half half to get to where you could actually Pick parts because now if you look we're actually getting little surface mount LEDs. So that's it's a lot closer So the next thing is is that they do have color And so you can you can pick out color here another thing you can do because I'll note that some of these are a little They're a little annoying because you're like well You know, what is green yellow versus green like green and green for example green can mean two different things and LEDs It can be like a yellowish green Which is let me try to remember the I don't know if they have the chemistry behind them, but there's like the in-gan in the IMP I don't think they have the chemistry Here how interesting they don't yep, they don't show you but they basically the chemistry I wish they make the LED determines that the color of the LED So some interesting colors like pink particularly there's there's no such real thing as a pink LED Usually it's a white LED that's painted over with like a pink paint And so the white shines through the pink and kind of lights up pink, you know, it's like a it's a painted light bulb So what you might want to do is To hear the lens color is you might want to look at the wavelength peak or the dominant wavelength either one Actually, I'm gonna deselect independence. I think I'm seeing that there's RGB LEDs here. So Let me go back to this and I'm just gonna click standard Because I don't want I don't want the multi LEDs Okay, let me get a couple few so You know blue what does it blue mean versus like ice blue? This isn't where you might want to search by the wavelength so Let's see you can search for like nanometer wavelength Maybe color There's a whole bunch of You know, there's like these Diagrams That'll show you the nanometer wavelength. So if you're looking for something reddish You know, it's gonna be 740 and if you're looking for something like light yellowish you're gonna be like Actually, this isn't very good diagram. Hold on. Let me find a better diagram. Oh This is a better diagram. Okay Yeah, so this is if you want something yellow yellow greenish, it's gonna be maybe like 570 But what if you want like a deep greenish, it's gonna be 525 So let's look at for example like ice blue. That's probably gonna be like 470 or something before 75 So let's go back here cuz I was actually kind of curious about this ice blue color Where was I there you go Ice blue, so let's see what comes up when we search for ice blue Well, it's like one So this is a discreet ice blue LED. It does look like it's a you know White LED with like a maybe a phosphor on top of it and Oh, it doesn't have the dominant wavelength some of them sometimes they don't especially if it's Because it's a white LED and it's covered with a fluorescent so it's actually not a true single color So let's actually look for like a purple so purple or pink LED is gonna be more towards sorry More towards like at the end here. So maybe like 425 You can see here. It's like 435 or something so let's look at Let's go back and Look at the filters and let's look at there are so many options Hold on there you go Pink and purple. Let's see what comes up. So yeah, there weren't a lot of options for pink and purple and the and that the pink They do have and but it's It's unfortunately in this large Package, which it's not for me I mean like this will be a really beautiful pink LED because it's gonna have like this nice Phosphored it looks like it's probably a blue LED with a like a pink orangeish phosphor on top and the color mixes So yeah, this one also won't have a dominant wavelength or pink because it's actually a mix of colors However, this purple LED I feel it's pretty nice and it's fairly inexpensive. It's a marketplace. So it's from another Vendor, but this one does have it's a single In mid or LED so this purple ad is a true like single wavelength color LED So you're gonna get 420 nanometers, which is you know over here past blue or on this one. It's over here purple and Don't forget to also check the data sheets Because the day she could also have some really good info for example, it tells you Also, just verify the wavelength that also might tell you whether it's a The material so in again and so it's it's like they just push that blue What would normally be a blue LED all the way into purple just by doping it and Then the lens is water clear. That means that the light itself is purple Not, you know white painted over because that would be a different lens color that would be like a I think they would just call it like a milky white lens. Let's see what they call the pink one Let's look at this day sheet, which I didn't look at so I'm curious This one They say it's pink in again in Yeah, so this one it's like they don't they tell you the chromacity Because I guess it's covered, but they don't tell you what it is originally. Oh interesting. It's even been You're doing nice on these So for this one doesn't it doesn't again, you don't get a wavelength because it's it's it's a white painted Cover, it's not a clear lens so In the end I was like if well, this thing I'm a cool logo Did you check out this logo? That's cool. That's Venkel. I wasn't expecting that This is like a Company that Johnny Mnemonic gets his computers from that is very futuristic. I know that's cool. Somebody definitely Went to art. Venkel never never change, please. Yeah, dude. Do not don't get don't get normal Keep it weird. Okay, so this so actually like this one because I actually kind of like the idea of like a pure purple Light coming from this 0603 LED. So I think I'm actually going to go even though this one's pink For it to work on my PCB because I need to be a 603 I'm going to go with this one the CTL a 603 fp. So I'm actually going to try to get a couple samples of this Put it on the pink PCB and see how it looks. It might look really good and that is great search
