Tiny SMD Fuse Approved for Space Applications
Reliability and ruggedness take on a whole new meaning for electronics used in space applications. Thereâ€™s no repair truck that can come out and replace failing devices. Schurter has released a new SMD fuse type called the MGA-S that has passed the rigorous ESA/SCC Generic Specification No 4008 for space applications. The MGA-S is based on the design of Schurterâ€™s existing MGA. The fuse is hermetically sealed and constructed such that no arcs or gasses can escape with disconnects. Its performance provides consistent pre-arcing times and overcurrent disconnects at rated voltage, regardless of vacuum conditions. Stable derating curves at higher ambient temperatures and durability against mechanical vibration and shock are also requirements of the space industry.
The key differences between a fuse for aerospace and a standard fuse lies in the extensive testing, by means of a â€œBurn-Inâ€œ procedure to validate the correct performance of each fuse; the results are recorded. The MGA-S offers a standard 1206 footprint (3.2 mm by 1.55 mm), making it the smallest SMD fuse qualified for use in equipment for space.

The EC-8560/PXI-8565 extends more PXI slots from an ExpressCard-based laptop computer via a shielded cable connection up to seven meters (23 feet) in length. PXI devices installed in the extension PXI chassis behave and work as if they are directly installed in the host system and do not require any additional driver or software installation.
The EC-8560/PXI-8565 implements PCI Express-based control of PXI modules and consists of the EC-8560 ExpressCard extension card installed in a laptop computer, a shielded cable, and the PXI-8565 PXI remote extension card. The EC-8560 is in the ExpressCard/34 form factor, uses one x1 lane, and communicates with the extension PXI chassis via a shielded twisted copper cable. The PXI-8560 remote extension card then converts the PCI Express signal into a 32-bit/66 MHz PCI interface for additional PXI slots.
