The 7258-S is a board-mountable SMT fuse manufactured by Bel Fuse. It is a high-speed, high-current fuse ideal for overcurrent protection of high-power switching devices, particularly for power supply designs in standalone systems for AC power lines. It features a time-lag current-limiting function to limit high inrush currents, and it is designed with a soldered mounting type for a reliable connection. The 7258-S also has a low resistance value for improved current-carrying capacity and is rated for operation up to 250VAC/VDC. It is available with current ratings from 1A to 10A and is compliant to UL 248-14, CSA C22.2 No. 248.14 and RoHS standards.
