3、ENT NO. 037Z3 DWG NO. 13011 REV PAGE 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 relia
4、bility) and class K (space application) and a choice of case outlines and lead finishes are available and are reflected in the Part or Identifying Number (PIN). When available, a choice of radiation hardness assurance (RHA) levels is reflected in the PIN. 1.2 PIN. The PIN shall be as shown in the fo
5、llowing example: 13011 - 01 H X X Drawing RHA 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 shall meet the MIL-P
6、RF-38534 specified RHA levels and shall be marked with the appropriate RHA designator. A dash (-) indicates a non-RHA device. 1.2.2 Device types. The device type identifies the circuit function as follows: Device type Generic number Circuit function 01 SVRMH28, SVRMH28F EMI filter, 28V dc, 2.0 A 1.2
7、.3 Device class designator. This device class designator shall be 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 qualific
8、ation to MIL-PRF-38534 is required. H Standard military 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 shall be as designated i
9、n MIL-STD-1835, and as follows: Outline letter Case outline X 1.460” x 1.130” x .330” (see figure 1) Y 2.000” x 1.130” x .355” (see figure 2) 1.2.5 Lead finish. The lead finish shall be as specified in MIL-PRF-38534 for classes H and K. Finish letter “X“ will not be marked on the filter or its packa
10、ging. The “X“ designation is for use when lead finishes A, B, or C are considered acceptable and interchangeable without preference. 1.3 Absolute maximum ratings. 1/ Input voltage (continuous) - +37.5V dc Input voltage (transient, 1 second) -+50V dc Input current - 2.0 A Power dissipation (Tc = +125
11、C) - 1.0 W Lead temperature (soldering, 10 seconds) - +300 C Storage temperature - -65 C to +150 C 1/ Stresses above the absolute maximum rating may cause permanent damage to the device. Extended operation at the maximum levels may degrade performance and affect reliability. Provided by IHSNot for R
