Product Description
Littelfuse SMD075F-2 is a 0.75 A resettable fuse designed for protecting electrical and electronic circuits against excessive currents. The 30V rated fuse uses surface mount technology (SMT) ensuring compactness and suitability for high-density electronic boards.
This fusible device switches quickly from a low resistance state to a high resistance state during overload or short circuit conditions, automatically resetting once the fault condition is removed and power is restored. This maintenance-free design enables thousands of reset cycles, making it highly reliable for long-term applications.
With dimensions of 7.98 mm length, 5.44 mm width, and 3.18 mm height, it is suitable for use in various electronic configurations. Tin-plated terminals provide excellent conductivity and corrosion resistance. It has a power dissipation rating of 1.7W and can operate safely at temperatures up to 85°C.
Common industrial applications include security systems, power supplies and transformers, automotive and medical equipment, instrumentation and control systems, computers, peripherals, audio-visual, and telecommunications equipment.
Automatic reset ensuring protection without fuse replacement. Compact surface mount footprint suitable for modern electronics. High hold current reliability and rapid trip time of 0.3 seconds. Tin-plated terminals for durability and conductivity.
