Can anyone identify this manufacturer? We're finding a rash of these caps bad. I've dissected a few of them and found the internals dry and the leads corroded away.

Re: Bad caps beyond computers
The logo doesn't look familiar to me. Usually, axial leaded parts are GP types, not the better quality low impedance types. Sounds like some mfr's materials and/or processes are so poor that their parts are scarcely adequate to be
paper weights .

Re: Bad caps beyond computers
The cap is out of a power supply. It's part of a half wave rectifier circuit and parallels a zener diode. Inside the cap we found the positive lead had corroded away where it attaches to the aluminum plate. It also seemed dry as compared to a good cap.
Possibly overcharged or just defective?Comment

Re: Bad caps beyond computers
likely a poor quality cap or too much heat.Originally posted by GoldHEMI
had a zenith tv in today with short vertical sweep.
had a la7838 on a tiny heatsink with the pump up cap against it.
2 years of that killed a rubycon 105 c rated cap.
the thing runs so hot it browned the board.
i added a bigger heatsink while i was in it.
its a special hospital tv so they cant afford to toss these.
even with aspirin at 25.00 a dose.Comment
