VERIFICATIONS 4.1 Product assurance program. The product assurance program specified in MIL-PRF-55342 and maintained in accordance with MI
28、L-STD-790 is not applicable to this document. 4.2 Product level qualification. The product level qualification specified in MIL-PRF-55342 and MIL-STD-690 is not applicable to this document. 4.3 Conformance provisions. 4.3.1 Inspection of product for delivery. Inspection of product for delivery shall
29、 consist of group A inspection and group B inspection of MIL-PRF-55342. 4.3.2 Certification. The procuring activity may accept a certificate of compliance in lieu of group B inspection (see 6.2d). 4.5 Visual and mechanical examination. Resistors shall be examined to verify that the materials, design
30、, construction, physical dimensions, marking, and workmanship are in accordance with the applicable requirements of MIL-PRF-55342. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging of materiel is
31、to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging activity within the Military Department or Defense Agency,
32、or within the military services system commands. Packaging data retrieval is available from the managing Military Departments or Defense Agencys automated packaging files, CD-ROM products, or by contacting the responsible packaging activity. 6. NOTES (This section contains information of a general o
33、r explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. Chip resistors are intended for use in thick or thin film circuits where microcircuitry is intended. Chip resistors can also be used in surface mount applications. 6.2 Ordering data. The contract or purchase order wil
34、l specify the following: a. Complete PIN (see 1.2). b. Requirements for delivery, one copy of the conformance inspection data that parts have passed conformance inspection, with each shipment of parts by the manufacturer. c. Packaging requirements. (e.g., Electrostatic discharge (ESD) sensitivity) (
35、see 5.1). d. Whether the manufacturer performs the group B inspection or provides a certificate of compliance (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 manufacture. Tin whiskers may occur
36、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 shown to inhib
37、it the growth of tin whiskers. For additional information on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin).

38、 SIZE A CODE IDENT NO. 037Z3 DWG NO. 02008 REV B PAGE 6 6.4 Electrostatic charge. Under several combinations of conditions, these resistors can be electrically damaged, by electrostatic charges, and drift from specified value. Users should consider this phenomena when ordering or shipping resistors.
39、 Direct shipment to the Government is controlled by MIL-DTL-39032 which specifies a preventive packaging procedure. * 6.5 Pulse applications. Designers are CAUTIONED on using the above resistors in high power pulse applications. Since they have not been qualified nor tested for such applications, da
40、mage and premature failure are possible. These resistors only see a one time pulse (Short-time overload) as part of the group B inspection of MIL-PRF-55342. * 6.6 User of record.
