Anti-Surge Wire Wound Resistors

The surge-proof wound wire resistor features a rated power range from 1W to 6W and a resistance range from 100 miliohms to 1.2 kilohms. Its welding points have undergone reinforced treatment, capable of effectively resisting surge impacts without breaking. The built-in alloy wire material possesses exceptional energy absorption capabilities, specifically designed to absorb harmful surge energy, making it highly suitable for applications in high-surge environments such as surge current protection for power capacitors, motor starting protection, and ignition systems for automotive and motorcycle engines. This characteristic ensures that the circuit is protected from potential damage risks caused by surge energy, thereby enhancing the overall stability and safety of the system.
