Hi,

I have 2 parts in a SMPS that I think are PTC thermistors. One is
marked KC103P, the other KC221K, the first a blue disk looking just like
this: http://uk.farnell.com/jsp/level5/mod...=en/207356.xml

The second actually looks more like a huge blue tantalum cap, smaller
than the first but fatter, not a disc.


If you Google these, you come up with all those companies that can sell
you 1000 at a time, but I can't find any data to tell me what they are
or an equivalent.

Acts like a short circuit to voltage spikes.
