Silicone insulation improves aerospace electronic high-voltage power supply MTBF

摘要

A lightweight, small-volume, electronic high-voltage power supply has been verified to have improved life characteristic when encapsulated with Silicone E rather than epoxy. High-failure-rate modules and two assembled power supplies were subjected to accelerated-life, thermal shock, altitude, and vibration tests to prove that Silastic E was a superior encapsulation medium.
