Identifying caps, PIO?

adalin · 22nd October 2004, 07:55 AM

Hi

I have a couple of capacitors in a box that I would like to Identify.

I was told that these where PIO caps but I don’t really know

They are made of Alu and looks like Electrolytcaps. And one side is marked with a line. But neither end is attached to the outside of the cap.

On the cap it’s printed:

__________________________
TCC

Metalpack

1uF

Working

350v. DC. 71º C

Type CP 91 N

British made

LE

Yes, they are PIO! good cap but tend to be leaky sometimes.

Please aslo find their patent marking "VISCONOL"

OK

My caps are perfectly fine. No leaks here. The rubber is fat and nice..

Is it a good brand, exept the risk of leaks?

Yes, it is a good brand and very expensive in Japan's market.
However, the brand is no longer exist or stop production.
Leaks is the only problem reported as I know.
