    Replacements for Nichicon PR and PL in PSU

    Hello, I have read the recommendation to use PS and PM respectively, but they are hardly available from here at decent prices.

    I've recapped this PSU with the following capacitors and I'd like to know if it will be ok. The reason I ask after recapping is that I've just realised that Nichicon PS 1000uF 16V is available at farnell for ~0.8€, so if you recommend me to change some more capacitors I'll get them in my next order.



    I indicate PS and PM (instead of PR and PL since I can't find this data) rated ripple current in mArms and impedance at 20ÂșC in ohms in parenthesis:
    • Nichicon PR 10uF 25V (160, 1.5) -> Rubycon YXF 10uF 100V (140, 1.2)
    • Nichicon PR 220uF 6.3V (220, 0.5) -> Rubycon YXJ 220uF 6.3V (250, 0.4)
    • Nichicon PR 1000uF 16V (1000, 0.11) -> Rubycon YXJ 1000uF 16V (1210, 0.062)
    • Nichicon PL 2700uF 6.3V (1700, 0.038)-> Panasonic FC 2700uF 10V (1945, 0.03)


    The unit works apparently perfect, but I made the error to buy the 1000uF 16V YXJ instead of YXF, being the latter more similar, and I'm worried about the ESR difference in this capacitor, should I replace this one with a Nichicon PS 1000uF 16V, or it's fine as is?

    Xbox 360 Xenon Modern Capacitor Replacements
    by burom
    I found my old Xbox 360 in storage and opened it up to see if there was anything that broke since it was built in 2006 (launch era Xenon revision, never red ringed, never been serviced) and didn't want to find out by releasing magic smoke. Upon moving the dust bunnies out of the way I was greeted by a bunch of capacitors with crud coming out of the top; it doesn't seem to have leaked onto the board so at least I have that going for me.

    I'm posting here because I want to try to source replacement caps myself from Mouser or Digikey instead of braving eBay or waiting for places to have...

    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

    1 x Capxon 1000uf35v...

    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...

    Please help find a replacement for Rubycon A0817 6.3V 1000uF 105C MBZ
    by omon
    Hi,
    I was hoping to get some help in identifying a replacement capacitor for a PET Rubycon A0817 6.3V 1000uF rated for 105C temp, MBZ series.

    This is to replace one bad capacitor on a DELL 530 motherboard DG33M03 (manufactured by Foxconn, DELL part # FM586).

    I'm attaching the pictures of the bad cap.

    Thank you so much!...

    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...
