*MIL-PRF-19500 covers screening requirements that all parts are submitted to as well as Quality Conformance inspection consisting of one or more of Group A, B, C, D and E for acceptance of the design of the process and of the production lot. *MIL-PRF-19500 applies to discrete components such as MOSFETs and Schottkys. QPL discrete components have been qualified per MIL-PRF-19500. For more information on MIL-PRF-19500 screening and quality conformance inspection, consult the DoD document or contact factory. *Beryllia warning per MIL-PRF-19500 Packages TO-254, TO-257, TO-258, TO-259 contain beryllium oxide (beryllia). Devices containing BeO are marked with designation “BeO” as per MIL-PRF-19500. |
