An experimental study of magnetic materials for use in ultrahigh-temperature electronic transformers

The very high temperatures that are expected to be encountered in aircraft and missiles are presenting unusual problems to the designers of electronic equipment and components. Two solutions that have been suggested are the following: 1. that more cooling capacity be introduced to maintain the equipment at a safe maximum operating temperature, and 2. the use of parts and processes that are inherently temperature tolerant over a wide temperature range. If the latter approach is taken, the component designer must make a major development contribution to extend successfully the ambient temperature rating of his device from a present-day 200 C (degrees centigrade) maximum to a value which is expected to be as high as 500 C.
