Brick Fuse--for over-current protection

475：

The 475 series is a fast-acting type brick fuse for over-current protection. As the fast-acting characteristics these fuses can resist inrush current. The 475 series fuse is mainly apply to primary protection on SMD PCB.

General Description : 475 SMD fuse for the small size and good electrical performance reliability and quality he solder-free design provides excellent on-off and temperature cycling characteristics during use and also makes our SMD fuses more heat and shock tolerant than typical brick fuses.
