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

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
