Abstract : Because of specific problems in the Rv and L07 resistors, a third unit was implemented. This was designated as the Rg resistor. It consists of the desireable design and processing factors of the two previous units. Considerable testing on the unit has demonstrated its capabilities in meeting the contractual requirements of this task. It has the commercial availability of the MIL-R-11 composition unit. The testing program included MIL-R-11 tests, Temperature-Load Matrix tests, Moisture Load tests, and Accelerated Moisture Load Tests. A failure analysis was performed on the results of each of these tests. A degradation model, based on chemical kinetics, has been derived from the constant stress temperature-load data for six resistance values. A paper study was performed which indicated the feasibility of the manufacture of an 1/8 watt unit capable of meeting the same failure rate objectives as those listed in the Technical Guidelines of this contract.
