Nichicon PC(M) replacement
Hello, Iam working on my dads EEC-IV computer from his 94 Lightning Pickup, it has bad nichicon PC(M) 2x47uf 16v and 1 10uf 63v what would be a decent replacement? I noticed Panasonic makes the General purpose NHG series any they are rated to 105c whould those be okay?
also on the bottom left of the board capacitor I see I guess a diode or something, it has no markings and had electrolite under it which i cleaned, did that cap possibly short it out?

Re: Nichicon PC(M) replacement
Heres a picture of the bad cap next to what I think is a diode? I see a black pool under it but is that electrolyte from the cap or the diode?

Re: Nichicon PC(M) replacement
It could be glue but then you would expect the same under other components so I guess not.
It looks like the board is conformally coated, maybe the electrolyte somehow dissolved that and created that mess... As for the cap choice I don't know because I did not find a datasheet for the Nichicon PC.

Re: Nichicon PC(M) replacement
Here is a datasheet for Nichicon PC...
If you want to be strict about it, you could use an automotive-grade cap like RX30 or similar. https://badcaps.net/forum/attachment...1&d=1614021069

https://www.mouser.com/ProductDetail...ysgx62ww%3D%3D I also found some guy trying the WURTH alluminum polymer caps, would those be a better choice since they wont ever leak again or would you go with the rubycons? Thank you for the help! |

Re: Nichicon PC(M) replacement
i would try to see what the caps do.
are they just smoothing dc, or on a dc/dc convertor output? or signal blocking? |
