Schurter Introduces UMF 250-Rated Current Extension

January 08, 2020 by SCHURTER Electronic Components

SCHURTER is now offering the UMF 250 in a total of 15 rated currents between 500mA and 15A.

The proven UMF 250 SMD fuse family is extended by a 15 A version. SCHURTER is now offering the UMF 250 in a total of 15 rated currents between 500 mA and 15 A. It is particularly suitable for electromobility applications with higher rated currents.

With its quick characteristics (small melting integral) according to IEC 60127-4, the UMF 250 is the logical addition to the successful UMT 250 range. It is sealed against potting compound to achieve a hermetic seal for use in intrinsically safe applications according to ATEX and IECEx requirements. Thanks to its high cycle stability and minimal temperature derating, it is extremely robust and resistant to ageing.

Thanks to its low internal resistance, the UMF 250 is ideally suited for primary and secondary protection on SMD circuit boards. Applications of the UMF 250 include the protection of battery-powered systems with high switch-off capacities of 500 A @ 125 VDC (e.g. electromobility). The fuse is also suitable for primary protection in the AC range, for example in voltage regulator modules and charging stations.


For lead-free soldering processes

The UMF 250 can is a halogen-free and RoHS-compliant fuse for lead-free soldering processes. The solder surface compatibility with the most important competitor products allows SCHURTER to offer the UMF 250 as a replacement product. The fuse is cURus approved. Available in 100 plastic bag or 2000 tape and reel packaging.


Unique Selling Proposition

  • High breaking capacity up to 200A

  • Low melting I²t-values, fast interruption
