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 solder alloys
and higher temperature profiles associated with lead-free
assembly.
Features
• Fast-Acting / Surface
mount high fuse for
voltage (up to 600VDC)
applications.
• Relatively high breaking
capacity at 100A.
• RoHS compliant /
Halogen Free
Agency Approvals
• Fully compatible with
lead-free solder alloys
and higher temperature
profiles associated with
lead-free assembly.
• Rating – 1 - 3.15
