Description：
The lead free NANO2 Slo-Blo® fuse is RoHS compliant,Halogen Free and 100% lead-free. This product is fully compatible with lead-free solder alloys and higher temperature profiles associated with lead-free assembly.The Slo-Blo® design 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：
• Lead-free and Halogen Free • Slo-Blo® • Small size • Wide range of current ratings available • Wide operating temperature range
• Low temperature de-rating
Applications：
Secondary protection for space constrained applications:
• Notebook PC • LCD/PDP TV • LCD monitor • LCD/PDP panel • LCD backlight inverter • Portable DVD player • Power supply
• Networking • PC server • Cooling fan system • Storage system • Telecom system • Wireless basestation • Game console
• Office Automation equipment • Battery charging circuit protection • Industrial equipment• Medical equipment • Automotive

Notes: - l2t calculated at 8ms. Resistance is measured at 10% of rated current, 25ºC
Temperature Derating Curve
Notes:
1. Derating depicted in this curve is in addition to the standard derating of 20% for continuous operation.
Example:For continuous operation at 75 degrees celsius, the fuse should be derated as follows:I = (0.80)(0.85)IRAT= (0.68)IRAT
