Following an intensive evaluation and qualification process in cooperation with representatives of the European Space and Research and Technology Center (ESTEC), SCHURTER's HCSF fuse has been certified. Eight years after the successful qualification of the MGA-S, SCHURTER is the only European supplier of fuses with this qualification.

The MGA-S is a surface mount fuse, which is manufactured with thin-film technology, hermetically sealed with the ceramic housing and designed to be extremely robust. Similarly, the HCSF fuse was developed for applications with higher rated currents.

Both fuses meet the exceptionally demanding requirements of the aerospace industry, e.g., consistent properties during operation in a high vacuum or an acceleration of 1,600g. Further relevant details about the products are listed in the respective data sheets (available to read or download below). Each article delivered goes through a specified burn-in test lasting 168hr at 85°C and 96% of the rated current. As a result, the failure rate of the fuse during operation is practically reduced to zero. The products are provided with an extensive test report.
