Thermometrics Type PTF PTC Type Thermistors consist of a range of radially-wired bare PTC disc thermistors. They are designed for general purpose over-current and short circuit protection.
Features
- Low cost solid state fuse
- Available in a broad range of resistances, transition temperatures and voltage ratings
- Exhibits large positive increases in resistance with temperature
- Resistance/temperature characteristic is infinitely repeatable and has no hysteresis associated with its action
- Proven quality and reliability over many years of manufacturing
