The latest addition to Schurter’s range of RoHS compliant products is the UMT 250 fuse-link. The UMT 250 offers the highest protection currently available in primary protection SM fuses, touting a breaking capacity rating of 200 Amps at 250 VAC or 100 Amps at 125 VDC over a current range of 315 mA to 4 A.

Measuring a small 10mm x 3mm x 3mm, the UMT 250 makes significant advances in the miniaturization of primary protection and process compatibility. It is an ideal replacement for the popular axial or radial lead through-hole fuses, such as the popular Mircrofuse. Using SM components, instead of through-hole components, results in lower production costs while providing higher reliability and quality of connection to the printed circuit board. The UMT 250 markings are clear, and visual identification of rated currents is easy for pick and place.

The UMT 250 fuse meets IEC 60127-4 and its equivalent UL 248-14. Its time-lag characteristics are especially suited for applications with inrush currents that require sustained fuse performance. The UMT 250 is ideal for power supplies and battery chargers. Also AC/DC converters, small IT equipment, health care devices, chargers for mobile phones, games and other home appliances such as electric shavers. The UMT is available in 100 piece quantities or 2000 piece reels for automated assembly. Lead-time is 5-10 weeks, depending on current rating.
