## Description

The Bel Fuse 0680L6300-01 is a high-reliability, slow-blow surface mount fuse housed in a compact 2410 ceramic package. Designed for robust circuit protection, this component supports a wide current rating range from 375mA to 12A, with this specific model rated for 6.3A. It features a ceramic body construction that ensures excellent thermal stability and mechanical durability, meeting MIL-STD-202G standards for shock and vibration resistance. With an operating temperature range of -55°C to +125°C and MSL 1 moisture sensitivity, this fuse is engineered for demanding environments, including automotive applications where it adheres to internal AEC-Q qualification standards.

This 2410-size SMD fuse is optimized for automated assembly, featuring compatibility with 260°C lead-free IR reflow soldering processes. It provides reliable overcurrent protection for a diverse array of systems, such as power supplies, battery charging circuits, PoE/PoE+ interfaces, and industrial automation equipment. The device is fully RoHS compliant and halogen-free, meeting EU Directive 2011/65/EU and 2015/863 requirements. With its precise time-current characteristics and high interrupting ratings, the 0680L series offers a dependable solution for protecting sensitive electronics in telecommunications, storage systems, and consumer hardware.
