7、R 97 1. SCOPE 1.1 Scope. This drawing documents five product assurance classes as defined in paragraph 1.2.3 and MIL-PRF-38534. A choice of case outlines and lead finishes which are available and are reflected in the Part or Identifying Number (PIN). When available, a choice of radiation hardness as
8、surance levels are reflected in the PIN. 1.2 PIN. The PIN shall be as shown in the following example: 5962 - 93192 01 H X A Federal RHA Device Device Case Lead stock class designator type class outline finish designator (see 1.2.1) (see 1.2.2) designator (see 1.2.4) (see 1.2.5) / (see 1.2.3) / Drawi
9、ng 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 the appropriate RHA designator. A dash (-) indicates a non-RHA device. 1.2.2 Device type(s). The device type(s) identify the circuit function a
10、s follows: Device type Generic number Circuit function 01 MFL2812D DC-DC converter, 60 W, 12 V outputs 02 SMFL2812D DC-DC converter, 60 W, 12 V outputs 1.2.3 Device class designator. This device class designator shall be a single letter identifying the product assurance level. All levels are defined
11、 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 Device performance documentation K Highest reliability class available. This level is intended fo
12、r 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 standard military quality class. This level uses the Class H screening and In-Process Inspectio
13、ns 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 devices which are based upon one of the other classes (K, H, or G) with exception(s) taken t
14、o 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 adversely affect system performance. D Manufacturer specified quality class. Quality level i
15、s defined by the manufacturers internal, QML certified flow. This product may have a limited temperature range.

MIL-STD-1835 - Interface Standard for Electronic Component Case Outlines. 1/ Stresses above the absolute maximum ratings may cause permanent damage to the device. Extended operation at the maximum
22、levels may degrade performance and affect reliability. 2/ An under voltage lockout circuit shuts the unit off when the input voltage drops to approximately 12 V. Operation of the unit between 12 V and 16 V is non destructive. At reduced output power, regulation may be maintained, but performance is
23、not guaranteed. 3/ These parts may be dose rate sensitive in a space environment and may demonstrate enhanced low dose rate effects.
