Afroman goes over some basic information about capacitors: Capacitance, voltage ratings and polarity. Once you know what you are doing, you can replace faulty caps on your circuit board and bring your electronics back to life! Don't forget to vote!

Panasonic FM series capacitors are usually a good choice.

    What is the use and difference of Low Impedance Electrolytic Capacitors vs regular ones ?

    Great video by the way thanks.

    I assume you are referring to low equivalent series resistance caps. Basically low ESR caps can handle higher ripple currents. Less internal resistance means less self heating when they are smoothing out power.

    How would you replace high voltage caps (200V etc), is there a safe way first "unload" them before removing them? I'm sure you know what i mean :P

    Great vids, keep them coming!

    greetings and all the best JJ

    HAPPY NEW YEAR evbd

    Afrotech is still around? Sweet! Used to just about piss myself reading that site back in my school days. And now my monitor has died and this advice might just save it. Amazing.

    I tried to explode a capacitor but it didn't. I used 25 volts from 3 9 volt battery. I checked the voltage with my multimeter and it worked. I had 25 volts But it didn't blew up the 19 volt rated cap.

    thanks for your input...you should do one about changing the capacitor on a home ceiling fan.

    They are ratet as pF. 1 is 1pF, 10 is 10pF, 101 is 100pF 102 is 1000pF or 1nF, 104 is 100000pF in other words 100nF or 0.1uF. the third value always tells how many zeros you have.

    how you can one tell which capacitors are BAD if they do not show any signs of obvious leakage ?

    what about ceramic caps?

    i can't figure out how to read the values.

    it's the same demonstration for both reverse-polarity and over-voltage.
