screening
Space Prototype (O), Class H, or Class K Radiation tolerant to
Radiation Hardness Assurance (RHA) levels of “-” (O) or “R”,
per MIL-STD-38534. Interpoint model numbers use an “O” in
the RHA designator position to indicate the “-” (dash) Radiation
Hardness Assurance level of MIL-PRF-38534, which is defined
as “no RHA”.
See “Class H and K, QML Screening” tables, page 10. Available
configurations: OO, HR, KR
