BG caps? Who makes them?

[kgordon]

One of the guys on one of my amateur radio lists mentioned some industrial switching supplies that used BG caps. All have failed within 6 months of use. He replaces them with Motorola brand caps and has had no failures since.

So, who makes BG brand caps?

Anyone know?

Mallory was a company that was known for making battery's

BG are some of the best and most expensive caps you can get for psu's - dont mix them up!

As an old Ham Radio Op (since 1956), I know that Mallory has also made capacitors since before WWII.

He insists that the BG caps have ALL failed within 6 months, repeatedly, as the PSU manufacturer has an excellent warranty and replaces them for free.

However, shipping costs are higher than replacing them himself with his choice of caps, which in this case is Mallory. He says that any PSU in which he has replaced the blown BG caps with Mallory's has never failed afterwards.

So, who makes BG?

and they arent rated for switching supply's, they are intended for Linear supplies - so they shouldnt have been used!
