SCHURTER UMT 250 Slow-Blow SMD Fuse, 315mA, 250V AC

The SCHURTER UMT 250 is a high-performance, surface-mount, time-lag fuse designed for robust circuit protection. Encased in a ceramic housing with tin-plated copper alloy terminals, this non-resettable fuse offers a reliable and permanent solution for safeguarding sensitive electronic components against overcurrent fault conditions.

Featuring a slow-blow (time-lag) characteristic, it can tolerate temporary inrush currents without nuisance tripping, making it ideal for applications with inductive or capacitive loads. The fuse boasts a high breaking capacity, capable of safely interrupting fault currents up to 200A AC and 100A DC, ensuring protection even under severe short-circuit scenarios.

Engineered for direct soldering onto printed circuit boards (PCBs), its compact 4012 case style saves valuable board space. It provides essential low-voltage primary and secondary protection in a wide range of electronic devices, meeting applicable international safety standards for reliability and performance.

With a maximum voltage drop of 750mV and power dissipation of 500mV, it ensures minimal impact on circuit efficiency. The component is rated for an extensive ambient operating temperature range from -55°C to +125°C and carries a UL94V-1 flammability rating for enhanced safety in its construction.

This fuse is a critical component for designers and engineers requiring dependable, space-efficient overcurrent protection in compact, high-density electronic assemblies.
