HaiWang NTC 20D-9 Thermistor – 20Ω 1A Inrush Current Limiter, NSP Power Type
The HaiWang NTC 20D-9 is a power-type negative temperature coefficient (NTC) thermistor designed for inrush current limiting in AC/DC power supplies, motor drives, and industrial control systems. With a cold resistance of 20Ω and a 1A steady-state current rating, it provides reliable surge suppression during circuit startup.
Features
- 20Ω cold resistance for effective inrush current suppression at power-on.
- Rated for 1A continuous current with minimal residual power loss after stabilization.
- NSP power-type construction for high energy handling and fast thermal response.
- Durable build ensures long-term reliability in industrial and automotive environments.
- Simple series installation in power supply lines for robust circuit protection.

The HaiWang NTC 20D-9 thermistor operates on the Negative Temperature Coefficient (NTC) principle, where its electrical resistance decreases significantly as its temperature rises due to self-heating from the inrush current. This characteristic allows it to present a high initial resistance (20Ω) to limit surge currents during power-up, which then drops to a negligible value under steady-state operation, minimizing power loss and thermal stress on the component.
Engineered for reliability, this power-type thermistor features a robust construction suitable for handling repeated surge events. Its fast response time and high B-value ensure effective protection for sensitive components like capacitors, transformers, and rectifiers in switch-mode power supplies, motor controllers, and LED drivers, preventing damage from current spikes and extending system lifespan.
