I have a Tantalum capacitor that needs to be replaced - 560pf/2Kv. I
have found a ceramic cap with the same values. Can I replace with the
ceramic, and what are the differences other than material of
construction? Thanks for your input.

A 2Kv Tantlum capacitor? Wow! Are you sure?

I would think that the ceramic capacitor would be a good choice for
replacement. Just make really sure that you replace with equal or
higher voltage rating. The materials of construction in capacitors of
similar ratings affect the following factors:

- Capacitor size
- Temperature stability
- Tolerance of capacitance
- Susceptability failure under over voltage transients
- Ageing characteristics

It's not tantalum.

Thanks Sam. It looks like one, and it is in the Horiz. of a Zenith. I
simply can't locate the replacement, so was looking to sub. Do you know
what type Cap this is? Thanks again to all.

It very oviously isn't though !

It'll almost certainly be ceramic or plastic film.

Almost certainly not a tantalum with a 2KV rating. They just don't go
up that high or down that low capacity wise. Tantalum caps are
electrolytic types, and polarized (never have seen a tantalum that
wasn't polar)..

I could believe it is ceramic - that's in the range of capacity and
voltage that makes it believable
