Bourns POWrTherm™ Power NTC thermistors

Bourns is pleased to debut its POWrThermTM Power NTC thermistors, which are high power rating NTC thermistors. NTC thermistors are commonly used as Inrush Current Limiters (ICLs) on power lines. 

Bourns® POWrTherm™ Power NTC thermistors are designed and constructed from various metal oxides which form the polycrystalline NTC thermistor bodies and are capable of suppressing high inrush currents with equivalent capacitance up to 1500μF @ 240VAC and a maximum current up to 15A. These seven model families are housed in radial leaded through-hole packages and are UL and/or TÜV recognized depending on the specific series.
