The Anti-Surge Wirewound MELF Resistor (SWM Series) offers a rated power range from 1W to 4W, with resistance values spanning from 1Ω to 1.2KΩ. It complies with the AEC-Q200 automotive-grade standard. While most wirewound resistors in the market are through-hole types and unsuitable for surface-mount processes, the SWM series breaks through this limitation by supporting SMT (Surface-Mount Technology).
Designed especially for high-pulse applications, the SWM series is ideal for use in circuits requiring protection against high inrush currents, such as power capacitor surge protection, motor start-up protection, and pre-charge/discharge systems in new energy vehicles. It effectively prevents circuit damage caused by sudden surges.
To enhance long-term operational stability and reliability, the SWM series has obtained multiple international patents, demonstrating its superior performance in critical applications.
