Automotive Grade/Vehicle Grade Anti-Surge Wire Wound MELF Resistors

The Vehicle Grade Anti-Surge Wire Wound MELF Resistor (SWM series) combines high performance with exceptional reliability, making it an ideal choice for demanding automotive applications. With a resistance range of 1 ohm to 1.2K ohm, it offers a wide range of options to suit various circuit requirements. The enabled SMD structure with MELF style not only enhances heat dissipation compared to traditional chip resistors but also boasts a robust mechanical structure capable of enduring high levels of vibration and thermal shock. The electrode-enhanced weld spot ensures reliable surge protection, providing an additional layer of safety against potential circuit damage.

Our products meet RoHS requirements and do not contain substances of very high concern identified by the European Chemicals Agency, ensuring compliance with environmental regulations. In addition, they are AEC-Q200 certified, guaranteeing their reliability and suitability for automotive applications. The SWM series is specifically designed for high surge applications, such as high rush current protection for power capacitors, motor start-up protection, and car & motorcycle engine ignition. By absorbing harmful surge energy, it effectively prevents circuit damage and extends the lifespan of automotive systems.

• Rated Continuous Maximum Working Voltage (RCWV) should be determined from RCWV = √(Power Rating x Resistance Values)
  

• Short - time Overload (STOL) test should be determined from STOL = 2.5 x RCWV
