Vehicle Grade Anti-Surge Wire Wound MELF Resistors - SWM
MELF style(SMD), high pulse load resistor
Vehicle Grade Anti-Surge Wire Wound MELF Resistor (SWM series) is offered in a resistance range of 1 ohm to 1.2K ohm. The enabled SMD structure with MELF style is better in heat dissipation than a chip resistor, and it has a stronger mechanical structure to endure vibration and thermal shock. The electrode-enhanced weld spot is reliable against surge. Our products meet RoHS requirements and do not contain substances of very high concern identified by the European Chemicals Agency. They are AEC-Q200 certified.
Vehicle Grade SWM series is applied in high surge applications such as high rush current protection for power capacitors, motor start-up protection, car & motorcycle engine ignition, etc., to absorb harmful surge energy, thus preventing the hazard of circuit damage caused by surge energy.
The SWM's structure is given patent approval from:
Taiwan patent number: M530462
Japan patent number: 3208923
China patent number: ZL201490001291.X
Korean patent number: 20-0486309
United States patent number: US9978483B2
