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 a
8、s 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 level. This le
9、vel 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 specified incoming
10、 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 specified in th
11、e 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 product ma

In the event of a conflict between the text of this drawing and the references cited herein, the text of this drawing takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific
20、exemption has been obtained. 1/ Stresses above the absolute maximum ratings may cause permanent damage to the device. Extended operation at the maximum levels may degrade performance and affect reliability. 2/ These parts may be dose rate sensitive in a space environment and may demonstrate enhanced
21、 low dose rate effects. Radiation end-point limits for the noted parameters are guaranteed only for the conditions as specified in MIL-STD-883, method 1019, condition A. Dose rate shall be in accordance with MIL-STD-883, method 1019, condition A. 3/ Bipolar device types may degrade from displacement
22、 damage from radiation which could affect RHA levels. These device types have not been characterized for displacement damage. 4/ See figure 3.
