**463 Series** NANO2[®] Fuse 

## **RoHS PSE** [_1HF Abus << C ~~E~~ A 

## **Description** 

The 463 series NANO²[®] is a fast-acting, very high current fuse designed for high operating current applications.  It offers superior thermal cycling endurance of 500 cycles with its low temperature rise and excellent temperature stability characteristics. It is ideal to be used in datacom and telecom equipment such as high end servers, base stations, power supplies, and blade computing applications. 

The 463 series offers high-amp circuit protection, ultra-high interrupting ratings (up to 500A@ 72VDC) and small size (10.1 mm x 3.12 mm x 3.12 mm) and surface-mount form-factor to help space saving.
