ABSTRACT:
A conductor for a fuse has a main composition of a Pb-Ag alloy containing silver of 0.5 to 20 wt. % and lead and unavoidable impurity for the rest. A conductor for a fuse in another example includes a Pb-Ag-Cu or/and Te alloy obtained by adding copper or/and tellurium of 0.05 to 1 wt. %, respectively, to the above mentioned Pb-Ag alloy. Each of those conductors for fuses has a diameter in the range from 0.05 to 0.3 mm and it is used as a fuse contained in a capacitor of a tantalum chip for example. Those conductors for fuses have excellent pre-arcing time/current characteristics and good drawability.
