Product Description
The PTC 19P 100Ω Thermistor is a high-performance positive temperature coefficient component based on barium titanate ceramic material. Designed for welder power supply startup, it is widely used in industrial control, automotive electronics, smart home systems, and more. Key features include:
Self-Recovery Function: Automatically resets to low-resistance state after abnormal current ceases, reducing maintenance costs;
Fast Response: Cuts off overload current within 5 seconds, protecting motors, batteries, and critical components;
Leakage-Free Design: Lower power consumption and higher safety compared to traditional fuses, ideal for precision electronics.
