When available, a choice of radiation hardness assurance levels are reflected in the PIN. 1.2 PIN. The PIN shall be as sh
7、own in the following example: 5962 - 91580 01 H X 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 marke
8、d devices shall meet 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 AHE2812S DC/DC
9、 converter, 20 W, 12 V output 02 AHE2812S/CH-SLV DC/DC converter, 20 W, 12 V output 03 AHE2812S/CH-MSTR DC/DC converter, 20 W, 12 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 requi
10、rements 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 performance documentation K Highest reliability class available. This level is intended for use in spac
11、e 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 standard military quality class. This level uses the Class H screening and In-Process Inspections with a pos
12、sible 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 devices which are based upon one of the other classes (K, H, or G) with exception(s) taken to the requir
13、ements 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 adversely affect system performance. D Manufacturer specified quality class. Quality level is defined by
14、 the manufacturers internal, QML certified flow. This product may have a limited temperature range.
