Resistors shall be uniform in quali
25、ty and free from any defects that will affect life, serviceability, or appearance. 4. VERIFICATION 4.1 Product assurance program. The product assurance program specified in MIL-PRF-914 is not applicable to this document. 4.2 Qualification inspection. Qualification inspection is not applicable to thi
26、s document. 4.2.1 Failure rate qualification. The failure rate qualification specified in MIL-PRF-914 is not applicable to this document. 4.3 Conformance inspections. 4.3.1 Inspection of product for delivery. Inspection of product for delivery shall consist of group A and group B inspections of MIL-
27、PRF-914. 4.3.2 Certification. The acquiring activity, at its discretion, may accept a certificate of compliance with group B requirements in lieu of performing group B tests (see 6.2d). 4.4 Inspection of packaging. Inspection of packaging shall be in accordance with MIL-PRF-914. 4.5 Visual and mecha
28、nical examination. Resistors shall be examined to verify that the materials, design, construction, physical dimensions, marking, and workmanship are in accordance with the applicable requirements of MIL-PRF-914. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall b
29、e as specified in the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain requisite packaging requirements. Packaging requirements are maintained by the Inv
30、entory Control Points packaging activity within the Military Department or Defense Agency, or within the Military Departments Services System Command. Packaging data retrieval is available from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by con
31、tacting the responsible packaging activity. 6. NOTES (This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. Chip resistors are intended to be used in thick or thin film circuits where microcircuity is intended, also, for us
32、e in surface mounting application. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-DEFENSE ELECTRONICS SUPPLY CENTER COLUMBUS, OHIO SIZE A CODE IDENT NO. 14933 DWG NO. 88036 REV B PAGE 7 6.2 Ordering data. The contract or purchase order should specif
33、y the following: a. Complete PIN (see 1.2). b. Requirements for delivery: One copy of the conformance inspection data or a certificate of compliance that parts have passed conformance inspection with each shipment of parts by the manufacturer. c. Packaging requirements (see 5.1). (i.e. Electrostatic
34、 discharge sensitive packaging). d. Whether the manufacturer performs the group B tests or provides certificate of compliance with group B (see 4.3.2). 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 manufactu
35、re. 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. Alloys of 3 percent lead, b
36、y mass, have shown to inhibit the growth of tin whiskers. For additional information on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). 6.4 Electrostatic charge. Under several combinations of conditions, these resistors can be electrically damaged, by e
37、lectrostatic charges, and drift from specified value. Users should consider this phenomena when ordering or shipping resistors. Direct shipment to Government is controlled by MIL-DTL-39032 that specifies a preventative packaging procedure. 6.5 Pulse applications. Designers are CAUTIONED on using the
38、se resistors in pulse applications. Since they have not been qualified nor tested for such applications, damage and premature failure are possible. These resistors only see a onetime pulse (Short-time overload) as part of the group B inspection. 6.6 Users of record. Coordination of this document for
39、 future revisions is coordinated only with the approved sources of supply and the users of record of this document.
