    1、AMSC N/A FSC 5905 INCH-POUND A-A-55517B 17 February 2010 SUPERSEDING A-A-55517A 12 December 2002 COMMERCIAL ITEM DESCRIPTION RESISTORS, FIXED, CARBON FILM, GENERAL REQUIREMENTS FOR The General Services Administration has authorized the use of this Commercial Item Description (CID) for all federal ag

    2、encies. 1. SCOPE. This CID covers the general requirements for a carbon film resistor. These resistor offer long term stability and may be considered as a substitute for carbon composition resistors. Requirements for specific resistors are covered in the individual CID specification sheets. For tech

    3、nical assistance when utilizing parts for parameters not specifically detailed (such as surge or high frequency applications) contact manufacturers listed on applicable CID specification sheets The resistors covered by this CID are intended for commercial/industrial application. * 2. CLASSIFICATION/

    4、PART OR IDENTIFICATION NUMBER (PIN). This CID uses a classification system which is included in the PIN as shown in the following examples (see 7.1). AA55517 01 * * CID number Applicable CID sheet (two digits) Resistance value (see 3.3 and 3.4) Resistance tolerance (see 3.5) 3. SALIENT CHARACTERISTI

    5、CS. * 3.1 Interface and physical dimensions. Resistors supplied to this CID shall be as specified on the applicable CID specification sheet. * 3.2 CID specification sheet. The family of carbon, film, resistors shall be in accordance with the requirements specified herein and the applicable CID speci

    6、fication sheet. Unless otherwise noted herein or in the event of a conflict between this general CID and the applicable CID specification sheet, the latter shall govern. 3.3 Resistance. The nominal resistance value expressed in ohms is identified by a three digit number; the first two digits represe

    7、nt significant figures and the last digit specifies the number of zeros to follow. When resistance values less than 10 ohms are required, the letter “R” is substituted for one of the significant digits to represent the decimal point. When the letter “R” is used, significant digits follow. Comments,

    8、suggestions, or questions on this document should be addressed to Defense Supply Center Columbus, ATTN: DSCC-VAT, Post Office Box 3990, Columbus, OH 43218-3990, or emailed to Resistordla.mil.

Minimum and maximum resistance values shall be as specified (see 3.1). 3.5 Resistance tolerance. The resistan

    10、ce tolerance is identified by a single letter in accordance with table I. TABLE I. Resistance tolerance. Symbol Resistance tolerance Percent () G J (Standard) K 2 5 10 3.6 Operating ambient temperature. The operating ambient temperature shall be as specified on the applicable CID specification sheet

    11、. 3.7 Marking. Resistors shall be legibly and permanently color coded with the manufacturers standard color coding. * 3.8 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally preferable materials should be used to the maximum extent possible provided

    12、that the material meets or exceeds the operational and maintenance requirements, and promotes economically advantageous life cycle costs. * 3.9 Workmanship. Resistor shall be processed in such a manner as to be uniform in quality and shall be free from other defects that will affect life, serviceabi

    13、lity, or appearance. 4. REGULATORY REQUIREMENTS. The offeror/contractor is encouraged to use recovered materials to the maximum extent practicable, in accordance with 23.403 of the Federal Acquisition Regulation (FAR). 5. PRODUCT CONFORMANCE PROVISIONS. 5.1 Product conformance. The products provided

    14、 shall meet the salient characteristics of this CID, conform to the producers own drawings, specifications, standards, and quality assurance practices, and be the same product offered for sale in the commercial market. The Government reserves the right to require proof of such conformance. 6. PACKAG

    15、ING. Preservation, packing, and marking shall be as specified in the contract or order. 7. NOTES 7.1 PIN. The PIN should be used for Government purposes to buy commercial products to this CID. See section 2 for PIN format example. 7.2 Environmentally preferable material. Environmentally preferable m

    16、aterials should be used to the maximum extent possible to meet the requirements of this specification. As of the dating of this document, the U.S. Environmental Protection Agency (EPA) is focusing efforts on reducing 31 priority chemicals. The list of chemicals and additional information is availabl

    17、e on their website at http:/www.epa.gov/osw/hazard/wastemin/priority.htm. Included in the EPA list of 31 priority chemicals are cadmium, lead, and mercury. Use of these materials should be minimized or eliminated unless needed to meet the requirements specified herein (see Section 3).” Provided by I
