Space Prototype (O), Class H, or Class K Radiation tolerant to Radiation Hardness Assurance (RHA) levels of “-” (O), “P” 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 for more information.
Available configurations: OO, HO, HP, HR, KR
