1WS 2WS 3WS Fusible Resistors Wire Wound Power Resistor

 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 fire-resistant wire-wound resistor boasts superior performance, effectively protecting circuits from overcurrent damage. It also features high-temperature resistance, solvent resistance, and corrosion resistance, ensuring long-term stable operation in harsh environments.

It employs a non-flammable insulating coating, effectively preventing the resistor from burning out in high-temperature and flammable environments, thus avoiding the risk of fire caused by overheating.

Furthermore, its low-temperature coefficient (200ppm/°C) ensures that the resistor maintains a stable resistance value even under significant temperature fluctuations, resulting in more accurate and reliable circuit operation. In the event of an overload, the resistor's uniform melting time allows for rapid and precise melting, preventing circuit failure or damage due to overcurrent.

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.
