Re: Need help identifying old capacitors

Just wanted to update:

I ordered all of those parts and they came in yesterday. I installed them and everything is working great! Thank you Mr. Budm

Re: Need help identifying old capacitors

Alright, so I heard back from Digi-Key and they just directed me to film caps. I also heard back from Kemet but they just directed me to a local sales rep.

After wandering around both Digi-Key and Mouser, my best educated guess is that the type of capacitor I need is Film, Polypropylene, High Pulse. Here are my proposed replacements:

Capacitor 1:
Top Markings: .0082H1600
Side markings: PSR, EVOX, 9321
Lead spacing: 15mm

Re: Need help identifying old capacitors



You are correct, the marking is actually PMR....

Re: Need help identifying old capacitors

And I'll email Digi-Key. I had no idea you could do that.

Thanks for replying by the way, I really appreciate your help!

Re: Need help identifying old capacitors

Any idea what capacitance the X/Y safety cap might be? I am guessing it is "10n", but I don't know what that means.

I also can't find any exact replacements for the baby blue caps, do you think if I up the voltage rating it will be OK?

Re: Need help identifying old capacitors

There are indeed side markings on those capacitors, here they are:

Capacitor 1:
Top Markings: .0082H1600
Side markings: PSR, EVOX, 9321

Capacitor 2:
Top Markings: 1.8J160
Side markings: FMR, EVOX, ???? (can't read the four numbers, can desolder part if needed)

Capacitor 3:
Top Markings:2.2J160
Side markings: PMR, EVOX, 9321

I have tried finding a schematic for the board, but no luck so far.

Hello everyone –

I am in the middle of restoring an old Macintosh all-in-one computer from the early 90s. It has a built-in Trinitron CRT monitor, and I am currently focused on rebuilding the analog board that drives it. The analog board is a combination of two power supplies and all the electronics that drive the CRT.

I have just finished replacing all electrolytic capacitors with brand new Nichicon, and now I would like to replace the three rectangular baby-blue colored caps that can be seen in this picture:



I am not sure what type...

Hi everyone, I'm Raul. I enjoy tinkering with electronics and keep hearing about this forum. Figured it was finally time to make an account. Cheers!
