Magnetics, Closed Construction Leaded and Surface Mount (transformers, inductors, coils) (Note: Stacking magnetics shall be
qualified and the effects of the long term performance of the hybrids verified. When stacking magnetics, a repeat of the thermal
cycling plus electrical measurements as specified in Group A of Mil-Std-981. Design, workmanship and materials/processes
shall conform to MIL-STD-981 requirements).
Magnetics, Open Construction are unencapsulated and unpotted self-leaded parts consisting of magnet wire wound around a
magnetic core. These parts are fully visually inspectable. Open construction magnetics shall be subjected to 100% electrical
measurements and visual inspection per Mil-Std-981.
