The picturization of the resistor above is a given representative of the envelope of the item. Slight deviations from the outline shown, which are contained within the envelope, and do no
39、t alter the functional aspects of the device are acceptable. 4. As a minimum the coating shall cover the total element of the resistor. FIGURE 2. Chip resistor array. Continued. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or
40、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 the Inventory Control Points packaging activity wit
41、hin the Military Department 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 the responsible packaging activity. 6. NOTES (T
42、his section contains information of a general or explanatory nature that may be helpful, but is not mandatory.) 6.1 Intended use. Chip resistor arrays are intended for use in thick or thin film circuits where microcircuitry is intended. Chip resistor arrays can also be used in surface mount applicat
43、ions. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-DRAFT DEFENSE SUPPLY CENTER, COLUMBUS COLUMBUS, OHIO SIZE A CODE IDENT NO. 037Z3 DWG NO. 99005 REV C PAGE 7 6.2 Ordering data. The contract or purchase order should specify the following: a. Compl
44、ete PIN (see 1.2). b. Requirements for delivery of one copy of the conformance inspection data or certification of compliance that parts have passed conformance inspection with each shipment of parts by the manufacturer. c. Requirements for packaging and packing. d. Whether the manufacturer performs
45、 the group B inspection or provides a certificate of compliance (see 4.2.2). 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 anytime from a day to years after manufacture an
46、d 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 tin whiskers. For additional in
47、formation on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). 6.3.1 Configuration A or B. Configuration A and B are inactive for new design due to the manufactures going to a pure tin termination to meet Restriction of Hazardous Substances (RoHS) directi
48、ves. 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. Direct shipment to the Government is controlled by MIL-DTL-39032 which specifies a preventive packaging procedure. 6.5 User of record.
