POWrTherm™ NTC Thermistors
Bourns' inrush current limiters (ICLs) are for power line protections ranging from consumer to industrial applications
Bourns® Circuit Protection Division is dedicated to high-quality and superior performance solutions, including overvoltage protectors (OVP), overcurrent protectors (OCP), and overtemperature protectors (OTP).
POWrTherm NTC thermistors are OCPs and act as ICLs, commonly used in switching power supplies, motors, amplifiers, and transformer applications. Bourns POWrTherm products are manufactured from various metal oxides to form polycrystalline NTC thermistor bodies capable of suppressing high inrush currents with equivalent capacitance up to 1500 μF at 240 VAC and maximum current ratings up to 15 A. They are offered in disc diameters 5 mm to 25 mm across seven model families.
- Seven disc diameter options: 5 mm to 25 mm
- Wide resistance range: 0.7 Ω to 220 Ω
- Highly stable electrical characteristics
- Coating material is flame-retardant to the UL 94V-0 Standard
- SMPS
- Amps
- DC motors
