Power Thermistors

Inrush Current Limiting Power Thermistor

ST Series Inrush Current Limiters

Description

Littelfuse inrush current limiters (power thermistors) are specially

formulated and processed NTC thermistors suitable for

suppressing high inrush currents in switching power supplies and

other applications where the high initial starting currents are

undesirable. Their unique design enables them to handle extremely

high current and voltage levels. In a typical power supply

application, the inrush current limiting power thermistor is used in

series with the filter capacitors. Upon application of the initial

voltage, the device, due to its relatively high resistance, limits the

current flow to an acceptable level until the capacitors are charged.

Thereafter, the device decreases in resistance substantially to a

level where the voltage drop across it is negligible.
