Description
MF72 5D15 NTC Thermistor – Inrush Current Limiter
The MF72 5D15 NTC Thermistor is a high-reliability negative temperature coefficient thermistor designed for effective inrush current limiting in power electronic circuits. It features a cold resistance of 5Ω and a 15mm disc diameter, allowing it to suppress high startup current while quickly transitioning to low resistance during normal operation. Supplied in a DIP through-hole package, the MF72 5D15 is easy to integrate into PCBs and power modules. It is widely used in SMPS, adapters, inverters, UPS systems, battery chargers, and industrial power supplies to protect components and improve system reliability.
