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 for more information.
Available configurations: OO, HO, HR, KR
