CL-110

The CL-110 is an NTC (Negative Temperature Coefficient) Disc Thermistor/Inrush Current Limiter with uninsulated lead-wires. It limits surge current by functioning as a power resistor which drops from a high cold resistance to a low hot resistance when heated by the current flowing through it. 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 the inrush current in switching power supplies, fluorescent lamp, inverters, motors, etc.
