Protection devices for constrained spaces

13 September 2017 Circuit & System Protection

Littelfuse offers a number of protection devices that are ideal for applications such as the Internet of Things.

The 468 Series Slo-Blo surface mount fuse (SMF) is a small (1206 size) thin-film device designed for secondary protection of circuits used in space constrained applications such as handheld portable electronic devices. A time delay feature withstands high inrush currents and prevents nuisance openings. This series is 100% lead-free and meets the requirements of the RoHS directive. Halogen-free versions are also available.

The SP3022 series of robust 0,35 pF, 20 kV bidirectional (back-to-back) discrete TVS diodes can safely absorb repetitive ESD strikes over the maximum level specified in the IEC61000-4-2 international standard without performance degradation. Their back-to-back configuration provides symmetrical ESD protection for data lines when AC signals are present. Their ultra-low loading capacitance (just 0,35 pF) makes them ideal for protecting high-speed data lines.
