    Advice and Recommendations

    Good day;
    I am putting together a Digi-Key order for some caps for use in general monitor repairs. I have noticed some caps are no longer available or I am just not looking in the right place. The caps I am having trouble with are:

    16v – 330uF
    25v – 33uF
    50v – .47uF
    450v – 100uF

    I am looking for the actual cap values or a suitable substitution with series.
    Thanks.

    All knowledge is good; it's how you use it that makes it bad.

    The voltage rating is not very important, as long as the replacements are of equal of higher voltage rating.

    So if you can't find 330uF 16v, you can use 25v or 35v rated capacitors, provided you can fit these larger diameter capacitors into the area you have on the boards.

    Same with the others. In fact, for those 33uF you could use 35v, 50v, 63v rated ones, for 47uF you can use 63v...

    The 450v rated capacitor is a reservoir capacitor.. the exact capacity value is not critical, you may be able to use 120uF capacitor instead if you can't find 100uF capacitors.

    Also, if you're located in US and the monitor will only run on 120v or about that value, you may actually be able to use a "reservoir" capacitor that's rated for lower voltage, like 350v. They're using 450v rated capacitors because in countries with 240v at the socket, the voltage on the capacitor goes up to about 370 volts. In US, you shouldn't get more than about 260 volts.

    Suitable capacitors for power supplies and monitors and so on are:

    Panasonic FM, FR, in the worst case FC
    Nichicon HM, HN
    Rubycon ZLH, ZLJ, ZLK
    United Chemi Con KZE

    For the large 450v capacitor, United Chemi-Con KXG , KMQ are popular in quality power supplies, other brands are also good but I couldn't tell you specific series.

    This site sells quite a few capacitors from the series above so you may get a better deal buying directly from here.

      Thank you for your quick and informative reply. This is the information I was looking for.

      I will be looking at the caps BC are offering; but I am ordering other items and need to get my total up for shipping. I will be ordering from this site in the future though. TC.

        SMD fuse soldering advice please
        by Ady2017
        Hi all. I need to replace an SMD fuse on my camcorder and this is the first time I have had to do any SMD soldering so your advice would be appreciated. Below is a picture of the board that I am working on and I have highlighted the fuse that needs to be replaced. I managed to zoom in to take this picture but the fuse is really tiny and is sandwiched between other components so this is going to be a new milestone for me. I appreciate that I am going to have to buy a new soldering iron if you could advice on what I need please. I was thinking about putting a big soldering iron across the whole...

        Operating caps well below rated voltage
        by Perry Babin
        I think this has been answered but I couldn't find the thread.

        Someone asked me if it would harm a capacitor (10F [not a typo], 24v) if it was operated on nothing more than 12v.

        So, I ask... Does it change any of the capacitor's characteristics/parameters/? in any way if it is never operated near rated voltage?

        If operated for years at 1/2 rated voltage, does it accept full rated voltage like it would if it had always been operated at the higher voltage?

        Or would it require reforming?

        Audio rated caps - is it ok to use ‘audio’ rated caps on a non audio device
        by Phil289
        Hi
        Just a quick question - is it ok to use ‘audio' rated caps on a non audio device.
        Is there any reasons why they shouldn't be used?
        I'm just trying to find some good quality caps on ebay for a small repair and I've noticed there are alot of audo rated caps in the size i need but not so many non audio rated.
        If I can't find any Panasonic what would be any other good makes to consider?
        Thanks 🙂

        A1289 Mac Pro "Early 2009" PSU (ACBel FS8001-291H, 614-0455)
        by MeltedDuron
        So a couple of days ago I picked up a 2009 8-core Mac Pro in "as seen" condition at a price that was too good to pass up, got it home, eventually managed to install OS X on it, and then it died while downloading updates. This machine looks like it was used for heavy video editing work as it still had a Blackmagic capture card and two GPU's installed, but I expect we'll see a lot more of these 2009 Mac Pro PSU's failing soon.

        After it died, the machine made some clicking noises, like it was trying to fire a relay but something wasn't working right, so it kept randomly clicking...

        CH341 programmer advice, including jumpers seemingly reversed
        by chazzo
        I’d appreciate some very basic advice on CH341x programmers. I know this topic comes up from time to time, but stuff changes, so I hope a refresh is in order. In particular, I see some unexpected things happening with jumper positions.

        [My plan is to learn to read and write 24CO2 EEPROMs via I2C. The first target is the one in my Uni-T clamp meter, but before tackling that I have some brand-new EEPROMs to practice on.]

        I have two basic Chinese programmers. One is the blue board with a CH341A and two rows of pin headers. To my untrained eye it looks like all the others....
