scope:
This drawing describes the requirements for hybrid microcircuit electromagnetic interference (EMI) suppression filters to be processed in accordance with MIL-H-38534. Two product assurance classes consisting of military high reliability (device class H) and space application (device class K) 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.
The PIN is shown in the following example:
Device classes H and K RHA marked devices will meet the MIL-H-38534 specified RHA levels and will be marked with the appropriate RHA designator. A dash (-) indicates a non-RHA device.
The device types will identify the circuit function as follows:
Device type Generic number Circuit function 01 FME-461 EMI filter, 15 A
The device class designator wilt be a single letter identifying the product assurance level as follows:
Device class Device requirements documentation H or K Certification and qualification to MIL-H-38534
The case outline will be as designated in MIL-STD-1835, and as follows:
Outline Letter Case outline X 3.00" × 1.50" × .400" (see figure 1)
The lead finish will be as specified in MIL-H-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 without preference.
