This drawing documents five product assurance classes as defined in paragraph 1.2.3 and MIL-PRF-38534. A choice of case outlines and l
5、ead finishes which are available and are reflected in the Part or Identifying Number (PIN). When available, a choice of radiation hardness assurance levels are reflected in the PIN. 1.2 PIN. The PIN shall be as shown in the following example: 5962 - 95562 01 H X X Federal stock class designator RHA
6、designator (see 1.2.1) Device type (see 1.2.2) Device class designator Case outline (see 1.2.4) Lead finish (see 1.2.5) / (see 1.2.3) / Drawing number 1.2.1 Radiation hardness assurance (RHA) designator. RHA marked devices shall meet the MIL-PRF-38534 specified RHA levels and shall be marked with th
7、e 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 MHP27028S DC-DC Converter, 65 W, 28 V output 1.2.3 Device class designator. This device class designa
8、tor 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, K, and E) or QML Listing (Class G and D). The product assurance levels are as follows: Device class Devic
9、e 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 applications where non-space high reliability devices are required. G Reduced testing version of the sta
10、ndard 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 manufacturer guarantees (but may not test) periodic and conformance inspections (Group A, B, C and D). E Designates
11、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 document; therefore the acquisition document should be reviewed to ensure that the exception(s) taken will not
12、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 temperature range. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-

In the event of a conflict between the text of this drawing and the references cited herein, the text of this dr
19、awing 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 perform
20、ance and affect reliability. 2/ An undervoltage lockout circuit shuts the unit off when the input voltage drops to approximately 120 volts. Operation of the unit between 120 volts and 160 volts is non-destructive at reduced output power, but performance is not guaranteed.Provided by IHSNot for Resal
