29、ming group B inspection and the moisture resistance test. 4.5 Short time overload. Resistors shall be tested in accordance with MIL-PRF-55342. The following details and exceptions shall apply: a. An overload dc test potential which will result in 5 times the rated wattage. b. Test board may have cop

Packaging requirements are maintained by the Inventory Control Points packagi
33、ng activity within the Military Department or Defense Agency, or within the military services system commands. Packaging data retrieval is available from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the responsible packaging activi

NOTES (This section contains information of a general or explanatory nature that may be helpful
35、, but is not mandatory.) 6.1 Intended use. Surface mount resistors are used in electronic circuits where space is a major concern. 6.2 Ordering data. The contract or purchase order should specify the following: a. Complete PIN (see 1.2). b. Requirements for delivery and one copy of the conformance i
36、nspection data or certification of compliance that parts have passed conformance inspection with each shipment of parts by the manufacturer. c. Requirements for packaging and packing. d. Whether the manufacturer performs the group B inspection and the moisture resistance test or provides a certifica
37、te of compliance (see 4.4.2). e. If marking is required (see 3.8.1). 6.3 Tin whisker growth. The use of alloys with tin content greater than 97 percent, by mass, may exhibit tin whisker growth problems after manufacture. Tin whiskers may occur anytime from a day to years after manufacture and can de
38、velop under typical operating conditions, on products that use such materials. Conformal coatings applied over top of a whisker-prone surface will not prevent the formation of tin whiskers. Alloys of 3 percent lead, by mass, have shown to inhibit the growth of tin whiskers. For additional informatio
39、n on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). 6.4 User of record. Coordination of this document for future revisions is coordinated only with the suggested source of supply and the users of record of this document. Requests to be added as a recor
