Schurter UMT-H SMD fuse

Schurter has extended its SMD fuses product family with a series which has high breaking capacity. Named UMT-H, the product has a breaking capacity of 1500 A. This makes the time-lag fuse suitable for applications with large short-circuit currents. Initially having six rated currents from 160 mA to 2 A, and having rated voltages up to 277 VAC and 250 VDC, it is an all-purpose component.

With all equal electrical specifications, the product has a competitive size, with dimensions of 5.3 x 16 mm making it more compact than traditional cylindrical fuses in 5 x 20 mm format. The square-shaped design keeps the device in place during reflow soldering. Due to the position of the device markings, key information about the fuse can be seen immediately.

Besides a wide range of applications in power circuits and sensors, the product is well suited for the primary protection of power supply units. A further application area is in industrial electronics. The high breaking capacity of 1500 A and the spacing between the end caps of >10 mm also make the devices useful in applications that involve explosion protection (IEC 60079-11).
