Abstract
The present hermetically-sealed electrical resistor component assembly is composed of a sleeve of high-density, non-porous, non-hydroscopic material into which there is slip-fitted an electrical resistor component. Said electrical resistor component is sealed within said sleeve by a deposit of solder at each end of said sleeve whereat said solder clings to said sleeve, to the end cap of said resistor, and to the lead wire extending from said end cap. In some embodiments silicon rubber is employed as a gasket disposed along the end of said cap whereat it abuts said sleeve. In another embodiment, the entire package is encapsulated in a plastic material such as silicone-epoxy.
