scope:

This drawing describes the requirements for hybrid microcircuit electromagnetic interference (EMI) suppression filters with transient protection and 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 shall be as shown in the following example:

Device class H and class K RHA marked devices shall meet the MIL-H-38534 specified RHA levels and shall be marked with the appropriate RHA designator. A dash (-) indicates a non-RHA device.

The device type shall identify the circuit function as follows.

Device type Generic number Circuit function 01 FM-704A EMI filter, transient suppression module

The device class designator shall 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 shall be as designated in MIL-STD-1835, and as follows.

Outline letter Case outline X 2.89″ × 1.124″ × .405″ (see figure 1)

The lead finish shall be as specified in MIL-H-38534 for class H and class K. Finish letter "X" shall 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.
