The SMD number shown is for Class H screening, non-
flanged, and no Radiation Hardness Assurance (RHA) level.
See the SMD for the numbers for other screening and radia-
tion levels. For exact specifications for an SMD product, refer
to the SMD drawing. Call your Interpoint representative for
status on the SMFL SMD releases which are “in process.”
