629慢断
629 Series Fuse 
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
? LCD/PDP panel ? Game console
? LCD backlight inverter ? Office Automation equipment
? Portable DVD player ? Battery charging circuit protection
? Power supply ? Industrial equipment
? Networking ? Medical equipment
? PC server ? Automotive
? Cooling fan system ? Storage system
