Abstract: A fusible resistor has a substrate on which two terminal paths are formed. A resistor in the form of an area of resistive material deposited onto the substrate extends between the terminal paths. The expected line of fracture of the substrate, upon a current flowing through the resistor such that the rate wattage is exceeded, crosses at least one of the terminal paths. Desirably at least one line or zone of weakness is formed in the substrate.
