Anti-Surge Wire Wound MELF Resistors - SWM
MELF resistor, high pulse load resistor
The Anti-Surge Wire Wound MELF Resistor (SWM) features a power rating from 1W to 4W, with resistances ranging from 1 ohm to 1.2K ohm, and tolerance of ±1%, ±2%, and ±5%. The 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, thereby preventing the hazard of circuit damage caused by surge energy.
Due to its SMD-enabled structure with MELF style, it is better in heat dissipation than chip resistor, and it has a stronger mechanical structure to endure vibration and thermal shock. The electrodes are enhanced to weld more reliably against surge. SWM's structure has been 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. They are Anti-sulfur and AEC-Q200 certified.
