RESISTORS, FIXED, NON-WIREWOUND (POWER TYPE).
Abstract
An investigation into the failures in the RD37 and RD39 styles is presented. Substrate surface defects are described to be the major contributing cause of failure in life testing. The additional load-life testing of styles RD60, RD65, RD70 and RD35 has been completed. Preparation for full-scale pilot production of styles RD31, RD33 and RD35 were undertaken. Data for these styles and partial data for styles RD31, RD33, and RD 35 are included. The manufacture of resistors for pre-production testing of style RD37 is complete. The manufacture of pre-production resistors for style RD39 is about 70% complete. The initial test data received for style RD37 is being analyzed because of the difficulties encountered with the ceramic substrates. (Author)
