A-A-55088 Resistors, Flameproof, FusibleThis \(CID\) covers the general requirements for flameproof, fusible resistors. These resistors act as a wire-wound resistor and a fuse, and are used in applications where precise control of fusing point and time lags are necessary. These resistors eliminate fire hazard and circuit board damage due to overheated components. Resistors covered by this CID are intended for commercial/industrial applications and are not used in military systems needing stringent environmental and electrical requirements.

COMMERCIAL ITEM DESCRIPTION

RESISTORS, FLAMEPROOF, FUSIBLE

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 flameproof, fusible resistors. These resistors

act as a wire-wound resistor and a fuse, and are used in applications where precise control of fusing point

and time lags are necessary. These resistors eliminate fire hazard and circuit board damage due to

overheated components. Resistors covered by this CID are intended for commercial/industrial

applications and are not used in military systems needing stringent environmental and electrical

requirements.

2. CLASSIFICATION 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).

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 range shall be 0.2 ohm minimum to 200 ohms maximum. Specific

resistance values are specified in table I by dash number.

3.3 Resistance tolerance. Resistors are available in resistance tolerances (K) �10 percent, (J) �5

percent, and (G) �2 percent.

3.4 Operating temperature. The operating temperature range shall be -55�C to +150�C.

3.5 Temperature coefficient. The temperature coefficient shall be �150 ppm for less than 1 ohm, and

�50 ppm for 1 ohm and above.
