NOTES (This section contains information of a general or explanatory nature which may be helpful, but is not mandatory.) 6.1 Intended use. Transformers conforming to this drawing are intended for use when military sp

39、ecifications do 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 spe

40、cification exists and the product covered by this drawing has been qualified for listing on QPL 21038, this drawing becomes obsolete and will not be used for new design. The QPL 21038 product shall be the preferred item for all applications. Provided by IHSNot for ResaleNo reproduction or networking

The contract or purchase order should specify the following: a. Complete PIN (see 1.2). b. Requirements for delivery of one copy of the qual

42、ity conformance inspection data with each shipment of parts by the manufacturer. c. Whether the manufacturer performs the group A and group B tests or provides certification of compliance with group A and group B requirements. d. Requirements for notification of change of product to the contracting

43、activity, if applicable. 6.3 Replaceability. Transformers covered by this drawing will replace the same commercial device covered by 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 grow

44、th problems after manufacture. Tin whiskers 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 6
