5D-11 NTC Thermistor – Inrush Current Limiter for Power Supplies and Electronic Circuits

5D-11 NTC Thermistor – Inrush Current Limiter for Power Supplies and Electronic Circuits

The 5D-11 NTC Thermistor is a high-quality Negative Temperature Coefficient (NTC) thermistor designed to limit inrush current during the power-up of electronic equipment. By reducing the initial surge current, it helps protect sensitive components, extend equipment life, and improve the reliability of power circuits.

With its compact 11mm disc package, the 5D-11 is widely used in SMPS, AC-DC power supplies, battery chargers, LED drivers, inverters, UPS systems, adapters, and home appliances. As the thermistor heats up during operation, its resistance decreases, allowing normal current flow with minimal power loss.
