screening
Space Prototype, Class H, or Class K are radiation tolerant
to Radiation Hardness Assurance (RHA) levels of “-” (O), “P”,
“R”, or “F” per MIL-PRF-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 Screening Tables 1, 2 and 3 for more information. Available
configurations: OO, HP, HR, KP, KR, KF
