[INCH-POUND] A-A-55534/4A 23 December 2002 SUPERSEDING A-A-55534/4 19 February 1997 COMMERCIAL ITEM DESCRIPTION RESISTORS, FIXED, WIRE WOUND OR METAL ELEMENT, (POWER TYPE) STYLE VLV5 The General Services Administration has authorized the use of this commercial item description (CID) for all federal agencies. 1. SCOPE. This CID covers the general requirements for style VLV5 wire wound or metal element, power type, fixed resistors. The resistors covered by this CID are intended for commercial/industrial applications. 2. CLASSIFICATION. This CID uses a classification system which is included in the Part Identification Number (PIN). The PIN shall be AA55534/04- (plus a coded number) as shown in the following example. F | | Resistance tolerance (see 3.3) NOTE: This PIN has been derived in accordance with A-A-55534. AA55534/04 | | CID number - R010 | | Resistance value (see 3.2) B | | Termination finish (see 3.4) 3. SALIENT CHARACTERISTICS 3.1 Design and construction. The resistors supplied to this CID shall be as specified herein (see figure 1). 3.2 Resistance value. The resistance value shall be 0.005 ohm to 0.9 ohm. 3.3 Resistance tolerance. This style resistor is available in resistance tolerances F, H, and J (±1 percent, ±3 percent, and ±5 percent respectively). 3.4 Termination finish. The termination finish shall be identified by a single letter, B for tin/lead (Sn/Pb) (3 percent lead minimum) or T (Sn) for (100 percent tin). 3.5 Power rating. The power rating shall be 5.0 watt at +25°C. The power rating shall be linearly derated to zero at 275°C. Beneficial comments, recommendations, additions, deletions, clarifications, etc., and any data which may improve this document should be sent to: Defense Supply Center, Columbus, ATTN: DSCC-VAT, Post Office Box 3990, Columbus, OH 43216-5000, or telephone (614) 692-0553, or facsimile (FAX) (614) 692-6939.

Resistors, fixed, wire wound, or metal element (style VLV5). 3.6 Temperature coefficient. The temperature coefficient of resistance shall not exceed ±350 ppm/°C for resistance values 0.01 ohm and above or ±650 ppm/°C for reistance values below 0.01 ohm from -55°C to +275°C. 3.7 Marking. Resistors supplied to this CID shall be marked with the manufacturers standard commercial PIN. Marking of individual small devices (e.g. chips) is not required but is permitted; however, each unit pack supplied to this CID shall be marked with the manufacturer's standard commercial PIN. 4. PRODUCT CONFORMANCE PROVISIONS. Product conformance provisions shall be as specified in A-A-55534. 5. PACKAGING. Packaging shall be as specified in A-A-55534. 6. NOTES 6.1 PIN. The PIN should be used for Government purposes to buy commercial products to this CID. See section 2 for PIN format. 6.2 CAGE code. For ordering purposes, inventory control, and submission of these instruments to DSCC under the Military Parts Control Advisory Group (MPCAG) evaluation program, CAGE code 58536 should be used. 2 A-A-55534/4 6.3 Source of documents.
