Capacitors help

A capacitor labeled 2200uF 100wv 105c what are the voltage rating of these capacitors? 100v capacitors I can't find that size.

 

[Galu]

The voltage rating is 100V (WV simply means 'working volts').

For what application do you need them?

 

[Galu]

They are available e.g.

2200uF 100V Radial Snap In Electrolytic Capacitor Nippon 82DA221M100KC | West Florida Components


NEW 2200uF - 100V ELECTROLYTIC CAPACITOR 30x25mm | eBay


The eBay one is 105 deg C.

It's for a power acustik amplifier I found some, but all were too wide or too tall. 22*25mm is the size of these but 22*30 will work maybe 35mm tall can squeeze, I have 22*40mm now 100v and I will have to alter the bottom plate some to make them fit. I added a rail washer to fit them

 

[Galu]

So it's physical size that's the problem. That wasn't clear from your post, but now I understand.

Hope you can squeeze something in. I would stick to the 105 deg C temperature rating though.

I did I quess they had these made this small. For this amp. I had to use a spacer on the bottom plate cover. But it will work. Just waiting on some 47uh inductors and it should be fully repaired.

Thank you for the information on the wv. That will help me in the future.

digikey or mouser search by size

you can search by size in the filter on digkey or mouser. just check the box what uf. lead spacing, with, and voltage

I just finished recapping an amp with LM caps.
They weren't so hot.

Is the diameter critical?
This is 35mm D x 32mm H

100MXG2200MEFCSN35X25 is shorter still but 35mm D and out of stock most places.

 

[rhempz01]

Yes, there are sized like a 50-63v 3300uF capacitor, very small, and close together. There is no wiggle room between capacitors to use a larger diameter. Those are propabably the closest I have seen. The tallest is 35,mm or is that the diameter?

 

[Cartel]

yes 35 is the diameter.
for 2200uf 100v, 22mm diameter is not found.
If 22mm is the limit diameter, thats gonna be tough to find.

 

[Cartel]

If you could squeeze in 25mm but they are high 37mm and not in stock most places.

Only other way is maybe use axial caps on end in series, like 2 4700 50v.

Kinda like this:
