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 Certificatio
8、n 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 class lev
9、el. 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 specifi
10、ed 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 be spec
11、ified 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 flow. This

Compliance with MIL-PRF-38534 may include the performance of all tests herein or as designated
20、 in the device manufacturers Quality Management (QM) plan or as designated for the applicable device class. Therefore, the tests and inspections herein may not be performed for the applicable device class (see MIL-PRF-38534). The manufacturer may eliminate, modify or optimize the tests and inspectio
21、ns herein, however the performance requirements as defined in MIL-PRF-38534 shall be met for the applicable device class. In addition, the modification in the QM plan shall not affect the form, fit, or function of the device for the applicable device class. 1/ Stresses above the absolute maximum rat
22、ings may cause permanent damage to the device. Extended operation at the maximum levels may degrade performance and affect reliability. 2/ Device type 01 operation at temperatures between +85C and +125C is guaranteed, but no parametric limits are specified in table I. For operation above the recomme
23、nded maximum case temperature of +85C contact the approved source of supply. 3/ Unless otherwise specified, “Rated” load is 3.2 watts on the main (+3.3 volt) output and 10 watts each on the auxiliary (12 volt ) outputs.
