SG Series Inrush Current Limiting Thermistors

Surge currents which occur when electrical circuits are switched on can cause serious damage to sensitive electronic components which may exceed their rated values unless the surge is controlled. Damaging surges may be prevented by using Surge-Gard inrush current limiters.

      • High hot to cold resistance ratio
      • 30 types of stocked Inrush Current Limiting (ICL) thermistor

The Surge Gard Inrush Current Limiting thermistor is a special power NTC thermistor which is connected in series with the load.

At "switch-on" the thermistor limits the current due to its relatively high cold resistance.  As a result of current flow the thermistor self-heats, reducing it's resistance value and thus limiting damaging surge currents to the load.
