Anti-Surge Wire Wound Fast-Fuse MELF Resistors - SWMT | Surge Resistant MELF Resistor Manufacturer | FIRSTOHM

Manufacturer of SMD resistor, Power resistor with Fast-Fuse function. The Anti-Surge Wirewound Fast-Fuse MELF Resistor (SWMT), with an SMD-enabled structure, features a power rating from 1W to 4W, with resistances ranging from 1 ohm to 470 ohm. The enhanced welded spot between the alloy wire and the metal cap is reliable against surge. RoHS / REACH Compliant. The Anti-Surge Wirewound 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, the SWMT series is excellent in heat dissipation and offers surge withstanding performance, exceeding that of chip resistor. To further enhance reliability, the resistors feature an advanced combined anti-surge & fast-fuse structure; the embedded thermal fuse protects 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 has been given patent 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.
