485 Series Fuse
Description
The 485 Nano2 Fuse Series is a small, fast acting, surface
mount ceramic fuse rated at a remarkable 600VDC at its
small size and with 100A breaking capacity. It is primarily
designed for circuit protection in high energy applications.
This product is fully compatible with lead-free solders
alloys and higher temperature profiles associated with lead-
free assembly.
