SL32 0R536

The SL32 series BigAMP Inrush Current Limiter absorbs high amounts of inrush current when electrical equipment is turned on by offering a high resistance to current and quickly decreasing in resistance once steady state current begins to flow through the thermistor. In a switching power supply, the instantaneous surge energy is caused by the large input filter capacitors and AC input voltage. During the absorption of energy, the initial high resistance of the thermistor drops within milliseconds to a negligible resistance in preparation of allowing high levels steady state current to flow with a minimal loss of power through the circuit. The BigAMP inrush current limiter will absorb up to 260J of input energy and carry 36A of steady state current.

• Wide range of resistance
