Each subsystem making up a video doorbell requires overcurrent, overvoltage, and ESD protection. Littelfuse delivers, as seen in this block


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® fuse 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.
- Lead-free and Halogen Free
- Small size
- Wide range of current ratings available
- Wide operating temperature range
- Low temperature rerating
