What is this part? I dont think its a ceramic cap. I have alit of these and they have resistance.

 

Looks like an NTC

 

Could be a surge limiter (negative temperature coefficient) or PTC fuse.

And that resistance is . . . . . . . . . ?

 

Measure resistance, then take a measurement while warming it up.

 

Or perhaps an MOV or Metal Oxide Varistor used in power circuits for surge protection.

 

Would a mov have a number like .005?
Thats more like a capacitence number.

 

I found a pic of one one the internet on a circuit board and it says rtc next to the part

 

Sure R and not P ?
Or it may indicate (R)eglator) Thermo-Couple.
