This drawing documents five product assurance classes as defined in paragraph 1.2.3 and MIL-PRF-38534. A choice of case outlines and
5、lead finishes which are available and are reflected in the Part or Identifying Number (PIN). When available, a choice of radiation hardness assurance levels are reflected in the PIN. 1.2 PIN. The PIN shall be as shown in the following example: 5962 - 05239 01 K X X Federal RHA Device Device Case Lea
6、d stock class designator type class outline finish designator (see 1.2.1) (see 1.2.2) designator (see 1.2.4) (see 1.2.5) / (see 1.2.3) / Drawing number 1.2.1 Radiation hardness assurance (RHA) designator. RHA marked devices shall meet the MIL-PRF-38534 specified RHA levels and shall be marked with t
7、he appropriate RHA designator. A dash (-) indicates a non-RHA device. 1.2.2 Device type. The device type identify the circuit function as follows: Device type Generic number Circuit function 01 LS2803R3S DC/DC converter, 25 W, 3.3 V output 1.2.3 Device class designator. This device class designator
8、shall be a single letter identifying the product assurance level. All levels are defined by the requirements of MIL-PRF-38534 and require QML Certification as well as qualification (Class H, K, and E) or QML Listing (Class G and D). The product assurance levels are as follows: Device class Device pe
9、rformance documentation K Highest reliability class available. This level is intended for use in space applications. H Standard military quality class level. This level is intended for use in applications where non-space high reliability devices are required. G Reduced testing version of the standar
10、d military quality class. This level uses the Class H screening and In-Process Inspections with a possible limited temperature range, manufacturer specified incoming flow, and the manufacturer guarantees (but may not test) periodic and conformance inspections (Group A, B, C, and D). E Designates dev
11、ices which are based upon one of the other classes (K, H, or G) with exception(s) taken to the requirements of that class. These exception(s) must be specified in the device acquisition document; therefore the acquisition document should be reviewed to ensure that the exception(s) taken will not adv
12、ersely affect system performance. D Manufacturer specified quality class. Quality level is defined by the manufacturers internal, QML certified flow. This product may have a limited temperature range. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-S
