It is no longer possible to picture our every day life without electronics and included in this is one of the earliest inventions, namely the fuse as an over current protector. However, if fuses are to be used for applications in space, these components will be subjected to extremely high quality requirements: the components qualification process with the European Space Agency ESA is complex and demands quality assurance processes having exceptionally high standards. SCHURTER accepted this challenge and is the only European fuse manufacturer able to fulfil these rigorously high requirements. The latest SCHURTER Proof of Performance is called MGA-S and has an equally as long a life expectancy as a satellite: 20 to 30 years.

Fuses for over-current circuit protection have been used in space applications for a con-siderable period of time. With the MGA-S and as a manufac- turer of passive components, SCHURTER is not only able to provide a fuse product, which meets all requirements for this industry but is also qualified ac-cording to ESCC Generic Spe-cification no. 4008. As a listed supplier at ESCC and as a Euro- pean fuse supplier, SCHURTER offers a product that is made using thin-film technology. The standard version for industrial applications has been on the market since 1990 and has annual sales of more than one million pieces. This clearly demonstrates a stable manufacturing process toge-ther with operation at a high quality level. For the space version, where only narrow tolerances in the manufacturing process are accepted, eight thousands fuses have been manufactured and passed through the screening procedure. The customer TESAT in Germany has reported no fai- lures to date. This article gives an insight into the fuse’s technical data, its design, manufacturing process and application information.

Technical Data

For its type (Fig. 1) the fuse is very small (3.2 x 1.55 x 1.55 mm or a 1206 footprint) and is intended for use in both direct (DC) and alternating (AC) current circuits. They are capable of operation in an ambient temperature range of -55 °C to 150 °C including high vacuum environments (
