Notes:
1. Our EMI filters are designed exclusively with passive components providing maximum tolerance for space environment requirements.
2. 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”.
3. Space Prototype (O), non-QML, products do not meet all of the requirements of MIL-PRF-38534.
4. Redmond site, Interpoint, has a Radiation Hardness assurance plan on file with DSCC. Our SMD products with RHA “P”, “R," "F" and "H"
code meet DSCC requirements.
5. Space converters are available with Radiation Hardness Assurance (RHA) levels of “O” and “R” with the following exceptions:
SMRT28xxx is only available with Radiation Hardness Assurance (RHA) levels of “O” “P”, “R” and “F”.
SMHP120xxx is only available with Radiation Hardness Assurance (RHA) level of “O”.
Space filters are only available with Radiation Hardness Assurance (RHA) levels of “O” and “H”.
