 4. Uniform in fusing time.

This fire-resistant wirewound resistor possesses a range of outstanding properties. It excels not only in current overload protection, but its high-temperature resistance, solvent resistance, and corrosion resistance ensure long-term stable operation in harsh environments. First, it employs a non-flammable insulating coating, effectively preventing the resistor from burning in high-temperature and ignition-prone environments, thus avoiding the risk of fire caused by resistor overheating.

Furthermore, its low temperature coefficient (200ppm/°C) ensures that the resistor maintains a stable resistance value even under significant temperature fluctuations, making the circuit operation more precise and reliable. Its uniform melting time is also a major highlight; when the circuit experiences overload, the resistor melts quickly and accurately, preventing circuit system 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.
