Re: Mystery 80s Sanyo cap - perhaps polymer?



Maybe you're thinking of Illinois Capacitor? I've seen some caps from them from that time period that have the same epoxy seal. Lots of Sprague caps from the 70s had bright red epoxy seals too - I see a lot of those at work in old minicomputer equipment. They're all junk now sadly...the tiny caps just don't hold up.

It's definitely possible they're plain ol lytics with a weird seal...I'm just curious to see if there's someone in the woodwork somewhere who worked on the design team or something...

Hey all I've been working on a 1984 Sanyo 27" color TV which had a smattering of bad caps in the video switching circuit. I found this oddball little 1uF 25V cap which looks to me like an early polymer, but I can't find concrete info proving it. I know Sanyo was a big player in early polymer cap development and this is the time period where they were just getting on the market, so I'm wondering if anyone has crusty old datasheets that could help identify it and determine if my suspicions are right? It has the same epoxy end seal and font/formatting as some old stock Os-Cons I've got laying...

Re: New Members - please post your introductions here

Hey all. I'm CJ and I fix vintage electronics as a hobby - primarily vintage television, radio, computer and videotape equipment of all ages. With that I naturally change a lot of caps and over the years I've taken an interest in capacitor history as I certainly find a lot of oddball or interesting caps in lots of different equipment . I hope that I can share some of that completely useless knowledge with you all, or at least post some things that are interesting to see!
