37、4 REV B 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. Filters conforming to this drawing are intended for use when military specifications do not exist and qualified military devices that will perf

38、orm 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 exists and the product covered by this drawing has been qual

39、ified for listing on Qualified Products List (QPL) 28861, this drawing becomes obsolete and will not be used for new design. The QPL-28861 product should be the preferred item for all applications. 6.2 Ordering data. The contract or purchase order should specify the following: a. Complete PIN (see 1

40、.2). b. Requirements for delivery and one copy of the quality conformance inspection data or certificate of compliance that parts have passed quality conformance inspection with each shipment of parts by the manufacturer. c. Requirements for packaging and packing. d. Whether the manufacturer perform

41、s the group B tests or provides certification of compliance with group B requirements. e. Requirements for notification of change of product to acquiring activity, if applicable. 6.3 Tin plated finish. Pure tin plating is prohibited since it may result in tin whisker growth. Tin whisker growth could

42、 adversely affect the operation of electronic equipment systems. For additional information on this matter, refer to ASTM B545 (Standard Specification for Electrodeposited Coating of Tin). 6.4 Cataloging information. Dash numbers 001 and 002 should be cataloged under FSC 5910 as feedthrough ceramic

43、capacitors. 6.5 Replaceability. Filters covered by this drawing will replace the same commercial device covered by contractor-prepared specification or drawing. 6.6 Users of record. Coordination of this document for future revisions is coordinated only with the suggested sources of supply and the us

44、ers of record of this document. Requests to be added as a recorded user of this drawing should be in writing to Defense Supply Center Columbus, DSCC-VAT, P.O Box 3990, Columbus, OH 43218-3990, by telephone (614) 692-0562 or DSN 850-0562, or by email to capacitorfilterdla.mil. 6.7 Approved sources of
