The POSISTOR PTFL series PTC Thermistor features Murata's strong ceramic technology, offers a line-up with a broad range of sensing temperatures. Exploiting the PTC characteristic (a sharp increase in resistance above a certain temperature), the PTFL series thermistor is 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. Capable of sensing heat, temperature sensor is widely used to protect equipment and circuits. NTC thermistor is elements whose resistance falls with an increase temperature, while PTC thermistor displays an increase in resistance as temperature rises. Its characteristic temperature-resistance curves allow them to be used as temperature sensors. NTC thermistor finds a wide range of uses since it features high precision and good thermal response.
