The Dexerials Corporation SFK-3030 is a surface mount secondary protection fuse, part of the SFK Series. It is engineered for applications in power systems and high-power equipment, particularly for protecting Li-ion batteries from overcharging and overcurrent conditions.
This fuse achieves a rated current of 30 Amperes and is suitable for use with 6 to 9 cells in series. It operates with a rated voltage of 80 VDC and a rated breaking capacity of 80 A (UL/TUV). The fuse element is designed to melt and shut off the circuit during overcharging, simultaneously cutting power to an integrated heater for rapid circuit interruption. Its compact dimensions of 9.5 x 5.0 x 2.0 mm make it suitable for space-constrained designs.
The SFK-3030 features a fuse resistance of 1.3 mΩ and a heater resistance range of 18.8 to 31.2 Ω. It is designed for surface mounting, with recommended land sizes available for proper integration. This component is RoHS3 compliant and has an MSL rating of 1.
