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 resistance range of 1Ω to 1.2KΩ. Enabled SMD structure with MELF style is better in heat dissipation than chip resistor, and 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. AEC-Q200 certificated.
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, so to prevent the hazard of circuit damage caused by surge energy.
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
