notes

1. 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.

2. number of Outputs: S is a single output and D is a dual output.

3. Screening: A screening level of O is a space prototype and is only used with RHA O. See Table 9 on page 14 and Table 10 on page 15 for more information.

4. 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.
