Fast-acting and time-lag SMD fuses

27 March 2019 Circuit & System Protection

Bourns announced the introduction of three new families of fast-acting, fast-acting/low-voltage, and time-lag SMD fuses to complement its line of SinglFuse SMD fuse products.

The new SF-3812FG-T and SF-3812F-T model families are UL 248-14 listed, and the SF-3812SP-T model family is UL 248-14 listed and meets IEC 60127 requirements. All three families utilise a ceramic tube structure with gold-plated end caps to achieve higher rated voltage and breaking capacity.

These new fuses are intended for use in a variety of power and battery protection applications including power supplies, voltage regulator modules, PC servers, storage systems, battery management systems, PoE and Advanced Telecommunication Computing Architecture (ATCA) applications.
