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

Manufacturer of MELF resistor, high pulse load resistor. Anti-Surge Wire Wound MELF Resistor (SWM) features power rating from 1W to 4W, resistances range from 1 ohm to 1.2K ohm, and tolerance at ±1%、±2% and ±5%. SWM series is applied in high surge applications such as high rush current protection for power capacitors, motor start-up protection, Electric Vehicle, renewable energy storage etc., to absorb harmful surge energy, so to prevent the hazard of circuit damage caused by surge energy. Due to SMD-enabled structure with MELF style is better in heat dissipation than chip resistor, and stronger mechanical structure to endure vibration and thermal shock. The electrodes are enhanced weld spot become more reliable against surge. SWM's structure is given patents 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 Our products meet RoHS requirements and do not contain substances of very high concern identified by the European Chemicals Agency. Anti-sulfur and AEC-Q200 certificated. FIRSTOHM is a high-quality 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.
