MF72 10D-9 Thermistor – Inrush Current Limiter
The MF72 10D-9 is a Negative Temperature Coefficient (NTC) thermistor designed to act as an inrush current limiter, protecting electronic circuits from high surge currents during power-on. With its high initial resistance, it effectively reduces the inrush current and then gradually decreases in resistance as it heats up, ensuring stable circuit operation. Compact, reliable, and durable, this component is widely used in power supplies, transformers, motor drives, and other electronic equipment requiring inrush current protection.
