Ordering Data
Specify type, resistance, tolerance, RoHS-Compliance and packaging.
This example is for a Metal Film Resistor, 1-watt, 1000Ω resistor.
Sample Part No.
CMF - 1 1001 F LF TR
IRC Type
CMF - Metal Film Resistor
Power Rating
(See specs table)
Resistance Value (EIA 4-digit code)
(≥100Ω - First 3 significant digits plus 4th digit multiplier)
Example: 100 ohms = 1000, 1000 ohms = 1001
(>100Ω - "R" is used to designate decimal)
Example: 10Ω = 10R0, 1Ω = 1R00, 51Ω = 51R0
Tolerance
F = ±1%; G = ±2%; J = ±5%
RoHS- compliance
LF = RoHS compliant construction
Packaging
TR = tape and reel only
