    Best caps to use on monitors

    i will like to get everybody's opinion on what caps are the best(in your opinion)
    being new to this world of monitor repair i dont really know what make to use and where to buy them.
    all opinions are appreciated and considered good.
    my goal its to use a component of best quality so i can get a long lasting repair.
    thank you everybody.

    Re: Best caps to use on monitors

    The best advice is to match the impedance/esr and ripple current as best as possible.

    Some circuits use capacitors that need low esr but can oscillate or be unstable in general with very low esr capacitors or basically damage capacitors within weeks or months if the esr is too high.

    Some linear regulators also require capacitors with specifications within a region, for example the esr must be between 0.1 ohm and 1 ohm - with such circuits we could recommend you some "best capacitors" but these would have esr much lower than 0.1 ohm and mess up the repair.

    So best advice.. read what's on capacitor, determine manufacturer and series (usually 2-3 digit code), search datasheet, get impedance and ripple value, find alternative. Impedance can be a bit lower, ripple can be higher in a new capacitor.

    Good series of capacitors are Panasonic FM, FR, Nichicon HM, HN, HZ, HW (low esr), HD, HE,PW, (not so low esr but good for low uf, high voltage capacitors), Nippon Chemi Con KZE, Rubycon YX*, ZL* and others but again, double check specs of old capacitors, there's no universal answer.

            Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
            by momaka
            I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

            For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

            https://www.badcaps.net/filedata/fetch?id=3591772

            It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

            Heathkit IO-4205 Power Supply Caps
            by eryjus
            Hello,

            First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

            I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

            I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

            Identifying caps on an old Zoom 9000
            by Paxman_Swede
            Hello!

            I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

            The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

            I have studied the board and...

            Help with switching power supply caps
            by captain150
            I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
            I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...

            Gigabyte GA-6OXT :: caps question
            by Foetuss
            Good evening

            I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
            Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

            But I was also suprised about the bigger boys, which are 330µF 25V.
            Could it be they used 25V caps because they were cheaper / available at that time?...
