[INCH-POUND] A-A-55534/9A 23 December 2002 SUPERSEDING A-A-55534/9 19 February 1997 COMMERCIAL ITEM DESCRIPTION RESISTORS, FIXED, WIREWOUND OR METAL ELEMENT, CHIP, (POWER TYPE) STYLE VLV2 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 VLV2 wirewound or metal element, chip, power type fixed, surface mount 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 AA55534/09- (plus a code 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. AA55534/09 | | CID number - R010 | | Resistance value (see 3.2) B | | Termination finish (see 3.4) 3. SALIENT CHARACTERISTICS. 3.1 Interface and physical dimensions. The resistors supplied to this CID shall meet the interface and physical dimensions as specified herein (see figure 1). 3.2 Resistance value. The resistance value shall be 0.005 ohm to 1.0 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) (100 percent tin). o 3.5 Power rating. The power rating shall be 2.0 watt at + 70 C. The power rating shall linearly derate to o zero at + 275 C (see 6.5).
