Abstract
The present device is a high reliability resistor comprising a sheet of metal foil secured to the flat side of a substrate and with the opposite side of the substrate formed to dissipate heat into the ambient thus enabling the present resistor to have an improved temperature coefficient of resistance (TCR) and further enabling the resistor to function satisfactorily in a high wattage mode.
