Thermometrics Type PTO PTC Thermistors consist of a range of radially-wired bare PTC disc thermistors for current regulation, circuit protection and temperature measurement and control. Available in a broad range of resistances, transition temperatures and voltage ratings.
Features
- Low cost solid state sensor
- 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
