629 Series Fuse                 from clipboard

Description

The NANO2 Slo-Blo® fuse has enhanced inrush withstand characteristics over the NANO2 Fast-Acting fuse. The unique time delay feature of this fuse design helps solve the problem of nuisance “opening” by accommodating inrush currents that normally cause a fast-acting fuse to
open.

Features

? Time-Lag (Slo-Blo)                                 ? Low temperaturede-rating
? Small size                                               ? RoHS compliant
? Wide range of current rating                   ? Halogen Free
   available (375mA to 12A)

? Wide operating temperature range
Applications

? Notebook PC                                        ? Telecom system
? LCD/PDP TV                                         ? Wireless basestation
? LCD monitor                                         ? White goods
