Qualification inspection is not required. 4.2 Conformance inspection. 4.2.1 Inspection of product for delivery. Inspection of product for delivery shall consist of groups A and B inspections
37、of MIL-PRF-28861 for class B. (The dc resistance/dc voltage drop test shall be performed on a sample basis as specified in MIL-PRF-28861 group A inspection table.) 4.2.2 Certification. The acquiring activity, at its discretion, may accept a certification of compliance with group B requirements in li
38、eu of performing group B tests (see 6.5c). 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When actual packaging of materiel is to be performed by DoD or in-house personnel, these personnel need to contact the
39、 responsible packaging activity to ascertain requisite packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging activity within the Military Service or Defense Agency, or within the Military Services System command. Packaging data retrieval is available
40、 from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the responsible packaging activity. 6. NOTES 6.1 Intended use. Filters conforming to this drawing are intended for use when military specifications do not exist and qualified milit
41、ary 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 exists and the product covered by
42、this drawing has been qualified for listing on QPL-28861, this drawing becomes obsolete and will not be used for new design. The QPL-28861 product shall be the preferred item for all applications. 6.2 Application note. These nonhermetically sealed filters may be susceptible to moisture intrusion whe
43、n subjected to repeated thermal cycling. If these items are to be utilized in applications enduring harsh environments, the user should consider placing them within hermetic enclosures. 6.3 Tin plated finish. Pure tin plating is prohibited since it may result in tin whisker growth. Tin whisker growt
44、h could 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 004 through 009 shall be cataloged under FSC 5910 as fe
45、ed through ceramic capacitors. Dash numbers 002, 003, and 010 shall be cataloged under FSC 5915 as radio frequency interference filters. 6.5 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 quality
46、 conformance inspection data or certificate of compliance that parts have passed quality conformance inspection with each shipment of parts by the manufacturer. c. Whether the manufacturer performs the group B tests or provides certification of compliance with group B requirements. d. Requirements f
47、or notification of change of product to acquiring activity, if applicable. e. Requirements for packaging and packing. 6.6 Replaceability. Filters covered by this drawing will replace the same commercial device covered by contractor-prepared specification or drawing. Provided by IHSNot for ResaleNo r
