5 x 20 fuse for SMT

28 February 2001 Circuit & System Protection

Why should one not use a 5 x 20 fuse as a SMD-component, if there is enough space for such a solution? Is it because of the missing heat resistance of the fuse during the soldering process? According to Schurter this is not a problem anymore with its new fuse types SMD 5x20 FST/FTT/SPT. The special coating of the caps guarantees good solderability.

The Schurter fuse types SMD 5x 20 FST/FTT/SPT offer a time-lag which has not been reached so far with 250 V DMD fuses and in the case of the SMD 5x20 SPT, a unique high breaking capacity of 1500 A/250 V IEC eg 10 000 A/125 V UL. Moreover, high rated currents up to 20 A are available.

Typical fields of application are the meter protection in general, power supply, battery protection and I/O modules.

The SMD 5x20 fuses from Schurter are available as taped in 2000 pieces per reel.
