7、mber Circuit function 01 MSK 5059RH Radiation hardened, 4.5 A, switching regulator controller 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 Cert
8、ification 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 space applications. H Standard military quality c
9、lass 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 possible limited temperature range, manufacturer
10、 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 requirements of that class. These exception(s) must
11、 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 the manufacturers internal, QML certified fl
