ESTEC, the European Space and Research and Technology Center and certification body of ESA, tested and certified the space fuses of the range MG-S from Schurter. They are SMD fuses, manufactured in thin-film technology, hermetically sealed and designed with a ceramic housing.
Space fuses with properties in high vacuum operation or accelerations
These space fuses meet the extraordinarily demanding requirements of the space industry, such as consistent properties in high vacuum operation or accelerations up to 1600 g. Since 2008 Schurter has been producing MGA-S fuses according to the agreed product requirements. The evaluation phase for the development of the requirements and solutions took four years. Each individual space fuse is subjected to a screening test. All measured values are recorded and handed over to the customer together with the delivery in a batch documentation. In requalification processes recurring every two years, ESA checks compliance with all technical production measures on the basis of defined qualification criteria.
Space fuses with switching characteristics
Currently, space fuses are used to protect redundant systems in satellites against short circuits or to switch them off specifically so that a replacement system can take over the function. Communication systems are also specifically switched on and off, for example to send data packets at a specific time. These switching characteristics cause high pulse loads when switching on, which must be absorbed by the fuses without tripping and without influencing their long-term switching off behaviour. Schurter is proud to be listed on the ESA website as a supplier of qualified products. The excellent quality of Schurter products is based on targeted development in close cooperation with their partners and the use of state-of-the-art manufacturing processes and production facilities.
