Abstract
A fuse for interfacing electrical current with electronic components and for shielding the electronic components from potentially damaging electrostatic discharge. The fuse includes a fuse body having an edge and first and second electrical contacts. A fuse indicator is connected to one electrical contact and a fuse element extends between the indicator and the other contact for providing a conduit for operating current to reach the interfaced electronic components. A window is disposed on the edge of the fuse body and positioned over the fuse indicator. Sealant is disposed between the window edge and the fuse body edge to prevent the accumulation of air therebetween and, thereby, preventing such accumulated air from functioning as a transmission medium through which an electrostatic discharge can travel and reach the electronic components.
