Corning Electronic Components

摘要

This project is concerned with the performance of a factorial load life test on Corning Glass Works' hermetically sealed, glass- NF resistors which are qualified to Characteristic G of MIL-R-10509D. The results of this test are in the form of detailed load life performance data. Resistors of two rated power dissipating capabilities, .125 watt and .250 watt have been tested. In this factorial test, approximately 21,000 resistors have operated at combin¬ations of temperatures of 70°C, 100°C, 125°C, and 150°C, and power dissipating levels of one time, two times, three times, four times, and five times their normally rated power for 2000 hours. In addition, 450 resistors have been tested for over 6000 hours and will continue to be under test up to 10,000 hours at 70°C under rated dissipating power. All resistors have operated under conditions as specified in MIL-STD-202 Method 108 and MIL-R-55182 Paragraph 4.6.17.
