Identify these parts?

metal oxide varistor. MOV

Acts like a short circuit to voltage spikes.

Makes sense now of course. Thanks.

This site ...

... suggests that the KC103P is manufactured by Murata Electronics North America.

This site ...

... lists the KC103M as a capacitor made by "S/M".

I suspect the part may be a high voltage 10nF ceramic cap.

It would help to know to which other parts these devices connect.

I think what your looking at is a MOV..

The PTC thermistors are from Keystone Carbon Corp., I used these some years ago. Not sure they are in business anymore, but the line may have been picked up by one of the components manufacturers.

I did find this :

But that might be new-old stock.

** That pic looks exactly like a regular NTC thermistor.

Mains voltage rated PTCs are used in the AC supply to PSUs, both transformer and switchmode to provide anti-surge PLUS overload protection.

Impressive to see one doing its job, running stinking hot while allowing only 25mA or so into the faulty PSU.

OOPs, that is indeed what I was thinking of, was NTC, not PTC, for inrush surge limiting.

You replied to a 17 year old message.

I've seen replies to older messages, but in this case, it's only been 7 years. 17 would have the original post in 1998.

And in this case, I seem to have missed the original post, so yes, it's amusing to see the other replies, which clearly came because of the first post.

It's often interesting to look at the original thread, because these old post resurrectors often don't. They think they have something to add, yet the original thread often covers the whole thing.

You're right. I had seen a 16 year old message replied to on another group a few minutes earlier, and wasn't paying close attention.
