Surge Current Limiters

Description

Spectrum Sensors & Controls Surge Current Limiters are a cost-effective way of limiting the inrush of current that can damage components in switching power supplies or other electronic devices.

These specially formulated NTC Thermistors have an initial high resistance that can limit current surge for up to several seconds. During this time, the heat generated within the device causes the resistance to decrease to a very low level. The resulting voltage drop across the Surge Current Limiter is negligible.

Surge Current Limiters are available in standard configurations, with a wide range of resistance and current carrying capabilities to fit your needs. They also can be custom designed to meet a variety of resistance, tolerance, size, lead configuration, and custom package specifications.
