ABSTRACT:
A fusible metal film resistor comprising a substrate of an electrically insulating material and a resistive film formed on the substrate, which consists of nickel, 4 to 12 weight % of phosphorus and 0.05 to 10 weight % of at least one additive metal of iron, tin, manganese and bismuth, has a stable and small temperature coefficient of resistance suitable as a precision resistor at a normal load and disconnects easily and rapidly at abnormal overload due to a rapid decrease of resistance at a high temperature which leads to fusion of the film as a result of heat generated by increased current.
