Resistor Code
3 Digit Resistor Code – Refer to the EIA Code noted above
Tolerance
J = ±5% (Standard) 3-digit code
G = ±2% 3-digit code (741-745 only)
F = ±1% 4-digit code (741-745 only)
X for zero ohm jumper
4 Digit Resistor Code (used only for 1% tolerance) – The first
three digits are significant and fourth digit is multiplier; “R”
indicates decimal on values less than 100 ohms.
Examples:
10R0 = 10 ohms
49R9 = 49.9 ohms
1000 = 100 ohms
1001 = 1,000 ohms
1002 = 10,000 ohms
