Vehicle Grade Anti-Surge Wire Wound MELF Resistors - SWM | Surge Resistant MELF Resistor Manufacturer | FIRSTOHM

Manufacturer of 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 Firstohm is a high-quality Vehicle Grade Anti-Surge Wire Wound MELF Resistors - SWM, MELF resistors, SMD resistors, metal film resistors, surge resistors, wire wound resistors, precision resistors, High voltage resistors, high Power resistors, metal oxide resistor, thin film resistors, fixed resistors manufacturer from Taiwan since 1969.
