Littelfuse 1.1 A Resettable Fuse 30V PolySwitch SMD100F-2

Littelfuse SMD100F-2 is a 1.1 A resettable fuse with a voltage rating of 30 V designed using PolySwitch technology for protecting electrical and electronic circuits from overcurrent and short circuits.

This surface mount fuse features a compact SMT footprint making it suitable for integration into various computer and electronics systems. It rapidly transitions from a low to high resistance state upon fault detection, automatically resetting once the fault is cleared and power is removed.

Key characteristics include a trip current of 2.2 A, hold current of 1.1 A, and power dissipation of 1.7 W. The fuse terminal material is tin plated, enhancing reliability and corrosion resistance. The device operates reliably within a temperature range of 0°C to 85°C.

Its small size with dimensions of 7.98 mm length, 5.44 mm width, and 3 mm height enables usage in compact electronic circuits, eliminating the need for fuse holders. Maintenance is not required as it supports thousands of automatic reset cycles, making it highly durable.

Common industrial applications include security systems, power supplies, transformers, automotive electronics, medical devices, instrumentation and control systems, computer peripherals, and audiovisual and telecommunication equipment.
