Anti-Surge Wire Wound MELF Resistors-Xseries - SWMX | High-Quality Resistors for Every Application | FIRSTOHM

Manufacturer of Wire wound SMD resistor with positive temperature coefficient characteristic against the surge.. Anti-Surge Wire Wound MELF Resistor X series(SWMX) features a power rating of 1W, resistance range from 1 ohm to 150 ohm, and tolerance at ±5%. SWMX series is applied in high surge applications such as high rush current protection for power capacitors, motor start-up protection, Electric vehicles, renewable energy storage etc., to absorb harmful surge energy, so as 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. SWMX's structure is given patents approval from: Taiwan patent number: I637420 Japan patent number: 6836669 China patent number: ZL201780088781.6 United States patent number: US10170266B2 FIRSTOHM is a high-quality Anti-Surge Wire Wound MELF Resistors-Xseries - SWMX, 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.
