Resistors shall be examined to verify that the materials, design, construction, physical dimensions, marking, and workmanship are in accordance with the applicable requirements 3.2, 3.3, 3.9, and 3.12. 4.5 Inductive reactance. When tested at 1 MHz and 30 MHz, the inductance reactance shall not exceed 10 nH for nominal resistance values less than 10 ohms, or 8 nH for resistance values greater than 10 ohms and less than or equal to 50 ohms. Measurements shall be made using a Hewlett-Packard model 4191A impedance analyzer and either Hewlett-Packard spring clip test fixture model 16092A or binding post test fixture model 16093A, or equivalent devices. Measurements with model 6092A fixture shall be taken with the resistor positioned between spring clips which are adjusted for 0.5 inch spacing. When using the model 16092A fixture, the resistor lead that is beyond the area of electrical contact on the signal (right side of the fixture) shall be bent 90 degrees vertically from the ground plane to reduce shunt capacitance. Measurements with the 16093A fixture shall be taken with the resistor positioned in a straight axial lead configuration between the (fixed position) binding posts so that the binding posts contact the resistor leads at the end of the body (nearly zero lead length). 4.6 Inspection of packaging. Inspection of packaging shall be in accordance with MIL-PRF-39017. 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 the responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Point's packaging activity within the Military Department or Defense Agency, or within the military service’s system commands. Packaging data retrieval is available from the managing Military Department's or Defense Agency's 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 that may be helpful, but is not mandatory.) 6.1 Intended use. The film resistors described herein are intended to be used in electronic circuits where semiprecision characteristic, low inductive reactance and small sizes are 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 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 the group B tests or provides certification of compliance with group B requirements (see 4.4.1.2.1). * 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 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 tin whiskers. For additional information on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin). * 6.4 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. These resistors only see a one time pulse (Short-time overload) as part of the group B inspection of MIL-PRF-39017. DEFENSE SUPPLY CENTER, COLUMBUS COLUMBUS, OHIO SIZE CODE IDENT NO. DWG NO.
