ABSTRACT:
An apparatus and method by which a flat film-type resistor is intentionally caused to thermal-shock fracture in response to a predetermined high-voltage overload condition. A stressed spring wire is mounted on such film-type resistor and connected in circuit with it. A predetermined solder and temperature gradient are employed to hold the spring wire in bent condition until the solder melts, whereupon the spring flexes and the circuit breaks. Heatsink portions are provided in the circuit board for such resistor, and receive terminal pins thereof.
