Product Description
RSG-I-FFA is a miniature cartridge fuse used in spacecrafts. The standards of implementation are SAST issued by Shanghai Academy of Astronautics No. 8 and CASTC issued by Beijing Academy of Aerospace No. 5. The products have been widely used in a variety of spacecrafts such as Shenzhou spacecraft, Tiangong I, II spacecraft, etc. The customers have been using the products which so far have never had any problem, and thus the guideline [foolproof" in aerospace industry is really achieved on the fuse. The specifications of the products ranging from 0.375A to 15A are available for selection. The product is able to adapt to a variety of harsh environments, and it can pass the rigorous tests such as damp, temperature energized screening, temperature shock, high temperature derating, vibration, etc. It can replace the fuse type FM08 manufactured by AEM company from the United States.
