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:

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.




Any help appreciated.,


thanks,


Gareth.
