Abstract
A thermal cut-off resistor that has an elongated thermal cut-off fuse; a wire-shaped resistor that is tightly coiled around the fuse, said resistor being physically connected to the fuse so that the fuse and the resistor are in an electrical series arrangement; and an electrically-insulated heat-resistant casing that contains the fuse and resistor therein and enables the fuse and the resistor to be secured and electrically connected to respective electrical contacts formed on a printed circuit board, the profile of the casing being approximately the width of the fuse.
