SCHURTER's UMT 250 fuse-link, available from Koloona Industries Pty Ltd , offers the highest protection currently available in primary protection surface mount 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.

This latest addition to SCHURTER's RoHS compliant range demonstrates a continuing commitment to environmental responsibility by developing components that lessen the impact of potential pollutants and at the same time meet customers' increasing demands for design compatible products.

Measuring a compact 10mm x 3mm x 3mm, the UMT 250 makes significant advances in the miniaturisation 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 whilst 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, such as power supplies and battery chargers. Additionally AC/DC converters, small IT equipment, health care devices, chargers for mobile phones, games, and other home appliances such as electric shavers would benefit from this innovative design.

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.
