Anti-Surge Wire Wound Fast-Fuse MELF Resistors - SWMT | High-Quality Resistors for Every Application | FIRSTOHM

Manufacturer of SMD resistor, Power resistor with Fast-Fuse function. Anti-Surge Wire Wound Fast-Fuse MELF Resistor (SWMT) with SMD enabled structure features power rating from 1W to 4W, resistances range from 1 ohm to 470 ohm. The enhanced welded spot between alloy wire and a metal cap is reliable against surge. RoHS / REACH Compliant. The Anti-Surge Wire Wound Fast-Fuse MELF Resistor possesses a stronger mechanical structure to endure vibration and thermal shock, aimed at a Fast-acting fuse device for high power applications. In fact, SWMT series is excellent in heat dissipation and offer a surge withstanding performance, exceeding that of chip resistor. Further enhancing reliability, the resistors feature an advanced combined anti-surge & fast-fuse structure, the embedded thermal fuse is protecting the circuit against overheating in electronic products. Flameproof multi-layer coating equivalent to UL 94 V-0, Safety and fusion test equivalent to UL 1412. SWMT's structure is given patents approval from: Taiwan patent number: I637420 China patent number: ZL201780088781.6 Japan patent number: 6836669 United States patent number: US10170266B2 FIRSTOHM is a high-quality Anti-Surge Wire Wound Fast-Fuse MELF Resistors - SWMT, 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.
