## 485 Series Fuse (Not Recommende ~~d for Automotive Applications)~~ 

## **Description** 

The 485 Nano[2®] 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.
