24、e tin. The use of pure tin, as an underplate or final finish, is prohibited both internally and externally. Tin content of resistor components and solder shall not exceed 97 percent, by mass. Tin shall be alloyed with a minimum of 3 percent lead, by mass (see 6.4). 3.6 Recycled, recovered, or enviro
25、nmentally preferable materials. Recycled, recovered, or environmentally preferable materials should be used to the maximum extent possible provided that the materials meet or exceed the operational and maintenance requirements, and promote economically advantageous life cycle costs. * 3.7 Manufactur
26、er eligibility. To be eligible for listing as an approved source of supply, a manufacturer shall be listed on the MIL-PRF-83401 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

Inspection of product for delivery shall consist of group A (M level part) and group B inspections of MIL-PRF-83401. 4.2.2 Certification. The acquiring a
30、ctivity, at its discretion, may accept a certificate of compliance with group B requirements in lieu of performing group B tests (see 6.2c). 4.2.3 Power conditioning. The power conditioning shall be performed at rated power. 4.3 Schematic J tests. For the tests on schematic J, the dc resistance meas
31、urements, resistance temperature characteristics measurement, and short time overload power application shall be made between each terminal and the application common terminal without compensation for the shunt circuits. The pin to pin dc resistance measurement shall be used directly to determine th
32、e acceptability to section 3 requirements. 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 to be performed by DoD or in-house contractor personnel, these personnel need to contact
33、 the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging activities within the Military Service or Defense Agency, or within the military services system commands. Packaging data retrieval is available fr
34、om 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 or explanatory nature which may be helpful, but is not mandatory.) 6.1 Intended use. Resis
35、tor networks are intended to be used in electronic circuit where miniaturization is required. 6.2 Ordering data. The contract or purchase order should specify the following: a. Complete PIN (see 1.2). b. Requirements for delivery: One copy of the conformance inspection data or a certificate of compl
36、iance that parts have passed 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 (see 4.2.2). d. Requirements for packaging and packing. * 6.3 Electrostatic
37、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 shipment to the Government is controlled by MIL-DTL-39032 that spe
38、cifies 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 to years after manufacture and can develop under typical operat
39、ing 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 tin whiskers. For additional information on this matter, refer to
