Space Prototype (O), Class H, or Class K
Radiation tolerant to Radiation Hardness Assurance (RHA)
levels of “-” (O) or “H”, 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, MIL-PRF-38534 Screening” tables for more
information. Available configurations: OO, HH, KH
