EN-318 evaluation of slow warm-up through special test of MC-890 type power supplies

摘要

ESE-171: This EN run was made to determine if there is any relationship between the H-5 transistor electrical characteristics, the assembly processes, and slow warm-up of the MC-890 Power Supply. Included is the test data on the H-5 transistors and the results of the High Temperature Life Test (185 (degrees)F) of 380 MC-890 Power Supplies.
