(See specs table)
Resistance Value (EIA 4-digit code)
(≥100Ω - First 3 significant digits plus 4th digit multiplier)
Example: 100Ω = 1000, 1000Ω = 1001; 150KΩ = 1503
(>100Ω - "R" is used to designate decimal)
Example: 10Ω = 51R0, 1Ω = 1R00, 0.25Ω = R250
Tolerance (EIA format)
G = ±2%; J = ±5%; K = ±10%
RoHS- compliance
LF = RoHS compliant construction
Packaging
TR = tape and reel only
