NOTES (This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. Capacitors conforming to this drawing are intended for use when military specifications do
36、 not exist and qualified military devices that will perform the required function are not available for OEM application. This drawing is intended exclusively to prevent the proliferation of unnecessary duplicate specifications, drawings, and stock catalog listings. When a military specification exis
37、ts and the product covered by this drawing has been qualified for listing, this drawing becomes obsolete and will not be used for new design. 6.2 Ordering data. The contract or purchase order should specify the following: a. Complete PIN (see 1.2). b. Requirements for delivery of one copy of the con
38、formance inspection data or certificate of compliance that parts have passed conformance inspection with each shipment of parts by the manufacturer. c. Requirements for notification of change of product to acquiring activity, if applicable. d. Requirements for packaging and packing. 6.3 Replaceabili
39、ty. Capacitors covered by this drawing will replace the same commercial device covered by a contractor-prepared specification or drawing. 6.4 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 whiske
40、rs may occur anytime from a day to years 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 s
41、hown to inhibit the growth of tin whiskers. For additional information on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). 6.5 Users of record. Coordination of this document for future revisions is coordinated only with the approved sources of supply and
42、 the users of record of this document. Requests to be added as a recorded user of this drawing may be achieved online at capacitorfilterdla.mil or if in writing to: DLA Land and Maritime, ATTN: VAT, Post Office Box 3990, Columbus, OH 43218-3990 or by telephone (614) 692-4709 or DSN 850-4709. 6.6 Cha
43、nges from previous issue. The margins of this specification are marked with vertical lines to indicate where changes from the previous issue were made. This was done as a convenience only and the Government assumes no liability whatsoever for any inaccuracies in these notations. Bidders and contract
44、ors are cautioned to evaluate the requirements of this document based on the entire content irrespective of the marginal notations and relationship to the last previous issue.
