    are any of these caps bad ones to use?

    Hi guys, first I want to thank you for having this forum. I have been reading a lot and slowly trying to learn a bit from the pros.
    I have been getting monitors from the local computer shop that have been turned in for recycling, so I can either repair them or take any usable parts and return the rest to be recycled.

    I live in a fairly remote area so there are not really a lot of options for electronic parts, I have been able to get my hands on the following caps and hopefully someone can tell me if they are good enough to be used to recap the monitors. Some of the series' I recognize as ones that people have said are good, but others I am not sure about, either because I have not seen that series mentioned yet, or the series letters are a little different that the ones that are said to be "good" ones.

    (I can provide pics if needed but hopefully the numbers and codes will be sufficient)

    A couple are black and gold with the "M" in a box so I think they are Panasonics, 22uF 50V 105C FM

    A couple are Rubycon 680uF 25V ZLH 105C (and a T1049 on it as well)

    also some that were ordered that should be here soon (limited info until I have them to confirm)


    all Panasonic

    25VDC 680uF EEU-FR1E681

    1000UF 16V EEU-FM1C102

    2200UF 10V EEU-FM1A222

    25VDC 1000uF EEU-FR1E102B

    1000uF 10V EEU-FM1A102

    220UF 25V EEU-FM1E221

    22UF 50V EEU-FM1H220

    I think the FM are one of the series' that is supposed to be good, but I am not sure about the FR.

    Would any of these be bad to use? There are just so many different ones with the same uF and voltage ratings and the prices are so varied as well it's very confusing. I am trying to learn the differences but it seems to be quite a process.

    Panny has never had any dud series, so all of those caps are fine.
    I love putting bad caps and flat batteries in fire and watching them explode!!

      Panasonic FR and FM are basically the same in terms of ESR and ripple, but in some sizes, FR has a longer endurance lifetime.

        Yes, the above is true, though you do need to know what series is suitable for the application. A SMPS requires low ESR caps like Panasonic series FR, FM, or FC.
