Product Description
GRF-S is a highly reliable surface mount fuse for space application, the volume of the fuse is similar to the fuse type 1206 surface mount fuse, with light weight, there is no welding defect on both sides of the electrode, there is extremely high reliability, electrical performance is more stable relative to the SCHURTER products for the same type, showing better arc extinguishing performance and higher insulation resistance after over load blowing or short circuit breaking. For the purpose of nothing wrong, the fuse is still keeping improving in the process. The fuse is applied to highly complex environments, and it is suitable for the high-end fields such as aerospace, military and civil equipment.
