To indicate the flanged case option change the “X” to
“Z” In the SMD number. The SMD number shown is for
Class K screening, non-flanged, and radiation hardness
assurance (RHA) level R. See the SMD for the numbers
for other screening and radiation levels. For exact speci-
fications for an SMD product, refer to the SMD drawing.

Notes
1. See Figure 4 above for an example of a model number.
2. Output Voltage: An R indicates a decimal point. 3R3 is 3.3 volts out. The values of 3.3 and 5.2 are only available in single output models.
3. Number of Outputs: S is a single output and D is a dual output
4. Case Options: For the standard case (Figure 27 on page 12) leave the Case Option blank. For the flanged case option (Figure 28 on page 13), insert the letter F
in the Case Option position.
5. Screening: A screening level of O is a space prototype and is only available with RHA O. See Table 9 on page 14 and Table 10 on page 15 for more information.
6. RHA: 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.” RHA O is only available with screening level O. See Table 10 on page 15 for more information.
