POWrTherm™ NTC Thermistors

Specifications

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 overcurrent protectors and act as Inrush Current Limiters (ICL) – 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@240 VAC and maximum current ratings up to 15 A.
