Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 3. REQUIREMENTS 3.1 General. The requirements for acquiring the product described herein shall consist
11、 of this document and MIL-R-10509. 3.2 Interface and physical dimensions. Resistors shall meet the interface and physical dimensions specified on figure 1. 3.3 Power rating. The power rating shall be 0.1 watt. For characteristic D, the power rating shall be 0.125 watt. 3.4 Voltage rating. The maximu
12、m continuous working voltage shall not exceed 200 volts. 3.5 Resistance. Minimum and maximum resistance values shall be as follows in table I. TABLE I. Minimum and maximum resistance.

13、e 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). 4. VERIFICATION 4.1 Sampling and inspection. Sam
14、pling and inspection shall be in accordance with MIL-R-10509. 4.2 Terminal strength. Direct load shall be applied gradually until the load reaches 2 pounds. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When
15、 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 within the Military Serv
16、ice 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.

21、resistors specified herein are not for use in design after 9 May 1972. They are authorized for use in design contracts effective prior to or on 9 May 1972. Existing equipment shall be supported by substitute resistors in MIL-PRF-55182/1 of the same resistance value, resistance tolerance, and charact
22、eristic performance of this specification regardless of failure rate designation. Resistors specified in MIL-PRF-55182/1 are preferred for design and regardless of failure rate designation can be used as substitutes for inactivated resistors of the same resistance value, tolerance, and characteristi
23、c performance of this specification. Characteristics C, E, and G were previously inactivated for design by revision F of this specification, dated 22 November 1968.

The use of alloys with tin content greater than 97 percent, by mass, may exhibit tin whisker grow
25、th 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.
26、Alloys of 3 percent lead, by mass, have shown to inhibit the growth of tin whiskers. For additional information on this matter, refer to (Standard Specification for Electrodeposited Coatings of Tin). 6.5 Pulse applications. Designers are CAUTIONED on using these resistors in pulse applications. Thes
27、e resistors are subject to damage and premature failures when they see excessive pulsing 6.6 Changes from previous issue. The margins of this specification are marked with vertical lines to indicate where changes from the previous issue were made. This was done as a convenience only and the Governme
