Press Release Summary:
UMT 250 SMD fuse offers breaking capacity of 200 A at 250 or 277 Vac, or 100 A at 125 Vdc over current range of 315 mA to 4 A. Measuring 10 x 3 x 3 mm, unit replaces traditional axial or radial lead through-hole fuses, and is solder immersion compatible according to IEC 60068-2-58. Clear marking of rated currents make it suitable for pick and place operations in manufacture of power supplies, battery chargers, ac/dc converters, health care devices, and consumer electronics.

Surface Mount Fuse Advances Circuit Protection
SCHURTER demonstrates its continuing commitment to environmental responsibility by developing components that lessen pollutants and at the same time meet customers' increasing demands for design compatible products. The latest addition to Schurter's range of RoHS compliant products is the UMT 250 SMD fuse. The UMT 250 offers the utmost protection of products in its class with a breaking capacity of 200 Amps at 250 VAC, 277 VAC or 100 Amps at 125 VDC over a current range of 315 mA to 4 A.
Measuring a small 10x3x3 millimeters, the UMT 250 maximizes circuit protection while enabling significant advances in miniaturization. It is an ideal replacement for popular axial or radial lead through-hole fuses. It provides similar performance, yet occupies approximately 80% less volume than a typical microfuse or 5x20 millimeter cartridge fuse. Surface mount components also provide higher reliability and quality of connection to the printed circuit board. The UMT is solder immersion compatible according to IEC 60068-2-58. Its markings are clear, and visual identification of rated currents is easy for pick and place.
The UMT 250 meets IEC 60127-4 and its equivalent UL 248-14. It is cURus and VDE approved. Its time-lag characteristics are especially suited for applications with inrush currents that require sustained fuse performance. These applications include power supplies, battery chargers, AC/DC converters, IT equipment, health care devices, and consumer electronics. The UMT 250 is also cURus approved at 277 volts, which is typical for electronic ballast applications. It is available in 100 piece quantities or 2000 piece reels for automated assembly. Lead-time is stock to 8 weeks, depending on current rating and volume. Pricing is $0.56 each in 100 pieces quantities.
