Re: Getting started in Electronics



0.015ufd 15kv non-polarized
Not impossible to find, though I only got one hit on the net googling
that value. They are about 3 inches long, 3/4inch round. The same shop
that had the neon light power supplies had the caps. It just wasn't the
first place I looked.

Much like the capacitors that go into speaker networks, I think they
make a large run of these things and sit on the inventory. So they are
cheap, generally, but near the end of the run, they are hard to find.
Nobody wants these big ass caps in modern electronics due to the size.

http://www.pupman.com/listarchives/1999/November/msg00275.html for the
google hit.

I did a circuit that needed an ultra low leakage capacitor. The cap was
nearly the same size as this 15kv beast. The thing looked laughable
next to the 8 pin dip. That particular cap was polystyrene. They are
popular in high end audio.
