Abstract
A thermally fused resistor arrangement wherein a resistor is electrically connected at one end to a first resistor terminal and at an opposite end to a second resistor terminal. A solder loop is provided to make the electrical connection between one end of the resistor and its corresponding resistor terminal. A portion of the solder loop is positioned in contact with an electrically insulated portion of the surface of the resistor, preferably corresponding to the hot spot of the resistor, and a thermally conductive medium is provided to thermally and mechanically attach the solder loop to the electrically insulated portion of the resistor surface. The portion of the solder loop thermally attached to the resistor is operable to melt when the temperature of the resistor increases to within a predefined temperature range, thereby electrically disconnecting the end of the resistor from its corresponding resistor terminal.
