The 120D-15 from Songtian Electronics is a Negative Temperature Coefficient (NTC) Thermistor that is designed to provide in-rush current limit and sensing functions for electronic devices. It has a current rating of up to 1.8 A and a resistance of 120 Ω. This REACH-compliant thermistor can sense and control current surges in circuits and reduces the risk of tripped circuit breakers, blown fuses, or damage to motors or filaments used in in-rush applications. It compensates for variations in circuit resistance caused by changes in ambient temperature in sensing applications. This RoHS-compliant thermistor is available in a through-hole package that measures 17.5 x 6.5 mm and is ideal for use in converter power, switch power, heater, ballast, electronic motor, transformers, adapters, projectors, halogen machines, LED drive circuits, and power circuit protection applications.
