PTFM series
PTC thermistors
Screw-fixing type
for overheat sensing

PTFM Series
The PTFM series includes overheat sensing components that can be attached easily using screws. Exploiting the PTC characteristic (a sharp increase in resistance above a certain temperature), these PTC thermistors are used for overheat sensing in FETs, power ICs, and other heat generating areas. Use of the sharp change in electrical resistance translates into outstanding noise resistance. 
Murata’s strong ceramic technology allows the company to offer a lineup with a broad range of sensing temperatures.
