UMT-H SMD Fuses Schurter UMT-H SMD Fuses feature a 100A to 1500A breaking capacity, allowing safe interruption at line voltage. They are ideal for applications with large short-circuit currents and for pulse-shaped continuous currents. These time-lage SMT fuses come in a 5.3mm x 16mm size, which is more compact than traditional fuses. Other features include rated currents from 160mA to 50A and high rated voltages up to 277VAC / 250VDC. Suitable applications for Schurter UMT-H SMD Fuses include primary protection on SMD PCBs, sensors, power supplies, battery protection, and much more.
