When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible
34、packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging activity within the Military Department or Defense Agency, or within the military services system commands. Packaging data retrieval is available from the managing
35、Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the responsible packaging activity.

36、NO. 037Z3 DWG NO. 97004 REV C PAGE 6 6. NOTES (This section contains information of a general or explanatory nature which may be helpful, but is not mandatory.) 6.1 Intended use. Resistors conforming to this drawing are intended for use when military specifications do not exist and qualified militar
37、y devices that will perform the required function are not available for the OEM application. 6.2 Ordering data. The contract or purchase order should specify the following: a. Complete PIN (see 1.2). b. Requirements for delivery: One copy of the conformance inspection data or certification of compli
38、ance 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 tests or provides a certificate of compliance with group B requirements. If purchase order makes no referenc
39、e to Group B screening the manufacturer will provide a certification of compliance (see 4.4.2.1). * 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 yea
40、rs after manufacture and can develop 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 whis
41、kers. For additional information on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). * 6.4 Pulse applications. Designers are CAUTIONED on using the above resistors in high power pulse applications. Since they have not been qualified nor tested for such a
42、pplications, damage and premature failure are possible. These resistors only see a one time pulse (Short-time overload) as part of the group B inspection of MIL-PRF-39017. * 6.5 User of record. Coordination of this document for future revisions is coordinated only with the approved source of supply
43、and the users of record of this document.
