    Re: FSP PSU and Capxon caps

    Hate to revive an older thread but finally got the caps in and since this is about this damn PSU again I felt starting a new thread wasn't right.

    I found some new Panasonic FR caps which are like the FM's but smaller but still had to use those Nichi's for that tight spot and replaced all the Teapo's and Capxon's. Now, wife's PSU is fixed, another PSU is fixed, but mine just keeps tripping the breaker as soon as AC is applied.

    I suck at switching power supplies so would like help if possible again. I'm thinking it is these 20N60C3 IGBT's as I get .1-.2ohm between collector and emitter and vice versa (though they are still soldered to the board as I didn't have time tonight to desolder them). I also get 22ohm from emitter to the gate on two of them while one is 2.2ohm (really). They are in parallel.

    From what I was looking at in their datasheet there shouldn't be any flow from E to C, am I correct in thinking that or totally off? I know I won't have 100% accurate readings while they are still attached to the board but am trying more prelim stuff before the deeper work. Nothing is fried or burnt and I quadruple-checked to make sure I didn't bleed over any solder.

    Also, oddly, the fuse hasn't blown in it.

    Any help, please? thank you!

        Capacitor Diarrhea - Nichicon PL Series
        by DrewPhillips
        Hello All, I have on the bench a couple of PSU's which have some failed Nichicon PL series caps. They didn't "puke" their guts through the top, but instead "diarrhea'ed" corrosive brown electrolyte through the bottom, down the legs and onto the board. On one cap, the electrolyte rotted the cap right off the board leaving 2 little stubs, and also corroded a trace on the foil side.

        The PSU's are Power-One MAP series and are ringing-choke topology. The semiconductors have date codes in 1993. The PSU's were used in a commercial application, fan-cooled. They had failed...

        Looking for best replacements for Capxons, but can't find data sheets
        by withalligators
        Recapping the power supply board for a Samsung 305T monitor, everything is Capxon except 2 Rubycons. I can't find data sheets matching these online, so don't know what ripple numbers, impedence, etc, to look for. There are a few different looking GL series data sheet PDFs, but the listing that matches the capacitance and voltage is a much bigger case size. I've narrowed down selections with lead spacing and case diameter, and what's in stock at Digi-key

        1 x Capxon 1000uf35v GL C720(is this a part number or batch number, can't find it anywhere) 105c

        Mid/late 80's Nichicon Yellow Caps
        by nick3092
        I recently acquired a set of Bose Roomate speakers from the mid to late 80's. Basically the right speaker cabinet is completely passive, and the left one has the power transformer and amplifier circuit in it. Out of curiosity, I opened it up to see what the circuit looked like. Looks like they used all Nichicon VX (2x 4700uF/16v for smoothing off the bridge rectifier), a couple random Nichicon SE series sprinkled on the board, and what really caught my eye - 2 yellow sleeved Nichicon caps (both 1uF/50v with no real series marking. Below are pictures of the caps. The only thing not shown in these...

        Vintage AT Power Supplies - Selecting Capacitors
        by iMic
        Hi,

        Back after a long hiatus with some old power supplies that need repairing. I've recently picked up a couple of 386SX systems, two 486DX systems, a SiliconGraphics Indy and an iMac G3 that either have verified leaking capacitors in their power supplies, or are likely to in the near future. For the sake of simplicity, instead of tackling all at once, I'm starting with the 386's and one of the 486's.


        The 386's power supplies are Seasonic SS4040A's, with caps that are visibly leaking, and 9 replacement caps per unit are required. Most appear to be from the Rubycon...

        Is there any datasheet for nichicon RT(M) series?
        by chth96
        A few days ago,I destroyed one of my japanese retro game console by pluging it to 220v outlet.
        https://www.badcaps.net/forum/troubl...e-been-blew-up

        and I finally fixed​ this retro game console by soldering varistor and glass fuse.

        But I noticed that When I measure voltage of PSU's 5pin connector, it is 8.80-9.07v, 5.13v,3.40-3.48v,GND,GND instead of its rated voltage of 9v 5v 3v GND GND.
        I have spare console...
