This example is for a Power Axial Wirewound, 2-watt, 1000Ω resistor.
Sample Part No.
CCW 2 1001 J LF BLK
IRC Type
CCW - Power Axial Wirewound
Power rating
(see specs table)
Resistance Value (EIA 4-digit code)
(≥100Ω - First 3 significant digits plus 4th digit multiplier)
Example: 100Ω = 1000; 1000Ω = 1001
(>100Ω - "R" is used to designate decimal)
Example: 10Ω = 10R0; 1Ω = 1R00; 0.25Ω = R250
Tolerance (EIA format)
G = ±2%
J = ±5%
K = ±10%
RoHS - Compliance
LF = RoHS compliant construction
Packaging
BLK = bulk packaging
