Product Overview
The SFH-1412B is a surface-mount chip fuse developed by Dexerials Corporation for high-current circuit protection. It is rated for 12 amps at 36 volts, making it suitable for low-voltage DC systems with elevated current demands. Additionally, its solder pad terminal configuration supports stable mounting during automated reflow assembly. The compact 5.4 mm x 3.2 mm x 1.35 mm body size helps designers conserve board space while maintaining robust electrical isolation.
Moreover, the fuse is designed to open reliably under overcurrent conditions, limiting damage to sensitive downstream components. Its halogen-free construction supports compliance-driven manufacturing requirements. Because of its stable electrical behavior across a wide operating temperature range, it performs consistently in both consumer and industrial environments. Consequently, the SFH-1412B is well-suited for battery-powered systems, embedded electronics, and power distribution paths where predictable protection is critical. Its Japanese manufacturing origin further supports expectations of quality and process control in high-reliability designs.
