Capacitor repair?

Post by gui_tarzan »

I have a new 100/450 cap that the positive lead broke off where it meets the can. Is there any way to salvage it? The connection is aluminum, solder won't stick.

It's possible. There might be a lead inside the can. But you'll have to cut it open to find out.

^^^^ Which is a long way to say it's not possible :)

Unless you can get a micro MIG/TIG machine and microsolder that leg to the aluminum stub.

Which is another way to say that it can not be done.

There's a reason aluminum electrolytic lugs or terminals are crimped .

It's not worth the effort for a nine buck cap!
I have repaired the leads on the other end, but always toss them if it's on that end!

It looks like it was attached with a small glob of JB Weld.
