34、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 activities within the Military Service or Defense Agency, or within the military services syst
35、em 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 or explanatory nature which may be he
36、lpful, but is not mandatory.) 6.1 Intended use. Resistors conforming to this drawing are intended for use when military specifications do not exist and qualified military devices that will perform the required function are not available for the OEM application.

37、uction or networking permitted without license from IHS-,-,-DEFENSE ELECTRONIC SUPPLY CENTER DAYTON, OHIO SIZE A CODE IDENT NO. 14933 DWG NO. 88014 REV E PAGE 7 6.2 Ordering data. The contract or purchase order should specify the following: a. Complete PIN (see 1.2). b. Requirements for delivery: On
38、e 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. Whether the manufacturer performs the group B tests or provides certification of compliance with group B requirements (see 4.2.1.
39、2.1). d. Requirements for packaging and packing. 6.3 Precautionary note. Due to the low profile of these parts and the length dimension required for the 12 pins, the parts are more fragile than regular parts and must be inserted into the boards with caution. * 6.4 Electrostatic charge. Under several
40、 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 which specifies a preventive
41、packaging procedure. * 6.5 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 operating conditions, on p
42、roducts 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 ASTM-B545 (Standard
43、 Specification for Electrodeposited Coatings of Tin). * 6.6 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, damage and premature failure are possible. * 6.7 User of record.
