Two product assurance classes consisting of class H (military high reliability) and class K (space applica
6、tion) and a choice of lead finishes are available and are reflected in the Part or Identifying Number (PIN). When available, a choice of radiation hardness assurance (RHA) levels are reflected in the PIN. 1.2 PIN. The PIN is configured as shown in the following example: 94028 - 01 H X X Drawing RHA

This level is intended for use in space applications. Certification and qualification to MIL-PRF-38534 is required. H Standard militar
10、y reliability level. This level is intended for use in applications where non-space high reliability devices are required. Certification and qualification to MIL-PRF-38534 is required. 1.2.4 Case outline. The case outline is designated in MIL-STD-1835 and as follows: Outline letter Case outline X 2.
11、89” x 1.11” x .405” (see figure 1) 1.2.5 Lead finish. The lead finish is as specified in MIL-PRF-38534 for classes H and K. Finish letter “X“ will not be marked on the filter or its packaging. The “X“ designation is for use when lead finishes A, B, or C are considered acceptable and interchangeable
