5mm Disc Type NTC Thermistor for Inrush Current Suppression Applications
The MF72-NTC**D-5 series is a disc-type negative temperature coefficient (NTC) thermistor designed for inrush current suppression in AC input lines or motor startup circuits. With a compact φ5mm ceramic body, this series provides a balance between low initial resistance and high energy handling, effectively limiting surge current during power-on and protecting downstream components.
