Marking is not required on the resistor; however, each unit package shall be marked with the PIN assigned herein (see 1.2), vendor CAGE code, and date and lot codes. 3.5 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally preferable materials

22、should be used to the maximum extent possible provided that the material meets or exceeds the operational and maintenance requirements and promotes economically advantageous life cycle costs. 3.6 Manufacturer eligibility. To be eligible for listing as an approved source of supply, a manufacturer sha

23、ll be listed on the MIL-PRF-55342 Qualified Products List for at least one part, or perform the group A and group B inspections specified herein on a sample agreed upon by the manufacturer and DLA Land and Maritime-VAT. 3.6.1 Certificate of compliance. A certificate of compliance shall be required f

24、rom manufacturers requesting to be an approved source of supply. 3.7 Workmanship. Resistors shall be uniform in quality and free from any defects that will affect life, serviceability, or appearance. 4. VERIFICATION 4.1 Product assurance program.

PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requi

28、rements shall be 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 packaging requirements. Packaging requirements are maintained by th

29、e Inventory Control Points packaging activities within the Military Service or Defense Agency, 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

30、 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 for use in thick or thin film circuits where microcircuitry is intended. Chip resistors can al

31、so be used in surface mount applications. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-DLA LAND AND MARITIME COLUMBUS, OHIO SIZE A CODE IDENT NO. 037Z3 DWG NO. 12014 REV PAGE 6 6.2 Ordering data. The contract or purchase order should specify the f

32、ollowing: 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. d. Whether the manufacturer performs the group B inspection or pro

33、vides a certificate of compliance (see 4.3.2). 6.3 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. Direct s

34、hipment to the Government is controlled by MIL-DTL-39032 that specifies a preventive packaging procedure. 6.4 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 anytime from a day

35、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 inhibit the growth of ti

36、n whiskers. For additional information on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). 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 su

37、ch applications, damage 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. Coordination of this document for future revisions is coordinated only with the approved source of suppl
