ABSTRACT:
A fan resistor is formed with a resistive pattern of electrically conductive material sandwiched between two panels of thermally conductive material. An insulating barrier on each surface of the resistive pattern electrically insulates it from the thermally conductive panels. The resistive pattern is cut from a sheet of metal using a stamping machine and the cut resistive pattern is dropped on one of the panels, a surface of which has an electrically insulating barrier thereon.
