7、REV H PAGE 2 1. SCOPE 1.1 Scope. This drawing describes the requirements for a 0.150 by 0.050 chip resistor, which is resistant to the degrading effects of moisture while under power. 1.2 Part or Identifying Numbers (PINs). The complete PINs are shown in the examples below. The first example is for

8、general military applications. (NOTE: This PIN is the original PIN shown in previous revisions of this drawing). The second example is for space type applications and requires adding a code letter to the end of the original PIN. NOTE: Example of military level PIN. 94026- * * * * | | | | | | | | | |

18、xceed the limits as specified in the moisture resistance requirements of MIL-PRF-55342. Samples subjected to this test shall not be delivered on the contract or order. 3.3.9 Outgassing (space levels A and T). Outgassing shall be performed as specified in MIL-PRF-55342. 3.4 Marking. Marking is not re

19、quired on the resistor; however, each unit package shall be marked with the PIN assigned herein (see 1.2), vendor CAGE code, and date and lot codes. 3.5 Manufacturers eligibility (military applications). The approved sources of supply listed on this drawing shall be qualified to at least one product

20、 on the Qualified Products List for MIL-PRF-55342. They shall have successfully passed the power moisture resistance test as witnessed and certified by an official company representative with 30 samples (10 low, 10 critical, 10 high) with zero defects. If the manufacturer has already performed the p

21、ower moisture resistance test to any of the following drawings (94012, 94013, 94014, 94015, 94016, 94017, 94018, 94019, 94025, 04007, 04008, 04009 or 07010) then performance of the power moisture resistance test as a prerequisite for being a source of supply is not required. 3.5.1 Manufacturers elig

22、ibility (space levels A and T). Only approved sources of supply qualified to “T” failure rate level of MIL-PRF-55342 and approved to the general military level of this drawing may supply to space level codes A and T. Furthermore all testing for these levels shall be done on a production lot basis as

23、 defined in MIL-PRF-55342. Test deletion or reduction, which may be granted for ER level product, is not allowed for space level codes A and T of this document.
