Anti-Surge Wire Wound Fast-Fuse MELF Resistors - SWMT
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
