Thermometrics Current Limiters
NTC Inrush CL Series
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.

Control of inrush current in switching power supplies, flourescent lamp, inverters, motors, etc.
