9、MOR2812S/883 DC/DC converter, 110 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 requirements of MIL-PRF-38534 and require QML Certification as well as qualification (Class H,
10、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 level is intended for use in
11、 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 flow, and the manufacture
12、r 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 the device acquisition docum
13、ent; 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 may have a limited temperatu

In the event of a conflict between the text of this drawing and the references cited herein, the text
21、of this drawing takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific 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
22、 performance and affect reliability. 2/ An undervoltage lockout circuit shuts the unit off when the input voltage drops to approximately 14.5 volts. Operation of the unit between 14.5 volts and 16 volts is nondestructive at reduced output power, but performance is not guaranteed. Provided by IHSNot
