Amphenol Advanced Sensors NTC Thermistor, NTC Type

The Amphenol Advanced Sensors thermometrics CL Series of inrush current limiting thermistors consists of a disc thermistor with uninsulated lead-wires, and are used to control inrush current when switching power supplies. The main purpose of limiting inrush current is to prevent components in series with the input to the DC/DC convertor from being damaged. Typically, inrush protection prevents nuisance blowing of fuses or breakers as well as welding of switch contacts.
