PTFL series
PTC thermistors
lead type
for overheat sensing

PTFL Series
Exploiting the PTC characteristic (a sharp increase in resistance above a certain temperature), the PTFL series 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. 
Featuring Murata’s strong ceramic technology, the PTFL series offers a lineup with a broad range of sensing temperatures.
