5、GE 2 1. SCOPE 1.1 Scope. This drawing describes the requirements for hybrid microcircuit electromagnetic interference (EMI) suppression filters to be processed in accordance with MIL-PRF-38534. 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
7、Device Device class Case Lead number designator type designator outline finish (See 1.2.1) (See 1.2.2) (See 1.2.3) (See 1.2.4) (See 1.2.5) 1.2.1 Radiation hardness assurance (RHA) designator. Device classes H and K RHA marked devices meet the MIL-PRF-38534 specified RHA levels and should be marked w
8、ith the appropriate RHA designator. A dash (-) indicates a non-RHA device. 1.2.2 Device type. The device type identifies the circuit function as follows: Device type Generic number Circuit function 01 FM-704A EMI filter, transient suppression module 1.2.3 Device class designator. The device class de
9、signator is a single letter identifying the product assurance level as follows: Device class Device requirements documentation K Highest reliability class available. 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
