Capacitor Replacement Sources and Concerns

[N4LTA]

I am sure that Mouser would have replaced them. Panasonic is the brand name for Mashusita, one of the largest component manufacturers in the world. The large distributors will replace them if they don't meet specs. I have never seen a Panasonic cap without the name either.

All electrolytic caps replaced. This did NOT happen:

Folks:

I have not taken the time to contact Mouser yet, and wonder if I will. The caps were a little low in value, within a standard -20%, +80% variance. From my memory, I think they were something like 42uf out of a rated 47uf. The markings on the caps matched the Panasonic data sheet, but neither the cap or the datasheet show that the cap having a Panasonic logo. To me, I wonder if Panasonic is buying generic caps. The original 20 year old Sprague cap had more capacity than the new Panasonics at the same published value. I get the feeling the old caps may eb manufactured with a tighter window than the new Panasonic caps.

Hope this clears up some confusion.

Modern caps are usually +/- 20% as the standard with 10% available; construction is different than the old Atoms which go back to pre WW2 where you could blow a rectifier if you got the +80% one and were pushing the tube specs a lot.

After a couple of million caps produced on the low side of bogey the money adds up.
