6、in paragraph 1.2.3 and MIL-PRF-38534. A choice of case outlines and 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 followi
7、ng example: 5962 - 99552 01 H U X Federal RHA Device Device Case Lead 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 me
8、et the MIL-PRF-38534 specified RHA levels and shall be marked with the appropriate RHA designator. A dash (-) indicates a non-RHA device. 1.2.2 Device type(s). The device type(s) identify the circuit function as follows: Device type Generic number Circuit function 01 AFL2803.3S/CH DC/DC converter, 6
9、6 W, 3.3 V output 1.2.3 Device class designator. This device class designator 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
10、 G and D). The product assurance levels are as follows: Device class Device performance 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 h
11、igh reliability devices are required. G Reduced testing version of the standard 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)
12、 periodic and conformance inspections (Group A, B, C and D). E Designates devices 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 d
13、ocument should be reviewed to ensure that the exception(s) taken will not adversely 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. 1.2.4 Case outline(s).
14、 The case outline(s) are as designated in MIL-STD-1835 and as follows: Outline letter Descriptive designator Terminals Package style U See figure 1 12 Y case configuration with leads bent upwards X See figure 1 12 Straight leads with end mounting through holes Y See figure 1 12 Straight leads with s
