1WS 2WS 3WS Flame Proof Resistor Wire Wound Resistors Small Type

 1. It is suitable for protecting circuit boards.
 2. Noncombustible insulating coating; Solvent Proof and resistant to high temperature.
 3. Low temperature coefficient ( 200ppm/°C ).
 4. Uniform in fusing time.

This flame-retardant wire-wound resistor boasts several superior performance characteristics, providing reliable overcurrent protection while exhibiting high temperature resistance, solvent resistance, and corrosion resistance, enabling long-term stable operation in harsh environments.

Its non-flammable insulating coating effectively prevents ignition under high temperature or flammable conditions, reducing safety risks caused by overheating.

Simultaneously, its low temperature coefficient (200ppm/°C) ensures stable resistance even under significant temperature variations, improving circuit accuracy and reliability.

Furthermore, its high consistency in fusing time allows for rapid and accurate fusing under overload conditions, effectively protecting the circuit system.

Fusible Flameproof Wire Wound Resistors (Small Type) are widely used in various circuit protection applications, especially in high-precision electronic equipment requiring protection against overcurrent, overheating, and other harmful effects. They are commonly used in power modules, inverters, power tools, electric vehicle charging systems, and home appliances. For power systems, especially high-power power supplies or frequency converters, they effectively prevent equipment damage caused by current surges. In automotive electronics, these resistors provide reliable current protection for on-board battery management systems (BMS) and battery charging systems, ensuring safety.
