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
