singles: 3.3, 5, 12, 15
duals: 5,12,15
triples*: 3.312, 3.315, 512, 515
“R” = decimal point, 3R3 = 3.3VDC
S (single), D (dual), T (triple)
OO** - Space prototype, HP, HR, KP, KR, KF
* for triple models “3.3” and “5” indicates the main voltage, “12” or “15” indicate the ± auxiliary voltages.
**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”
