Resistor Code
SIL (Single In-Line) network:• The 4 and 7 are significant digits and the 3 is the decade, giving 47 x 1000 or 47 K• The letter after the numbers is the tolerance. The different representations are:
M=±20%, K=±10%, J=±5%, G=±2%, F=±1%. • Detail Spec: http://www.vishay.com/docs/31509/csc.pdf
SMD (Surface Mount Device):• The 1 and 0 are significant digits and the 3 is the decade, giving 10 x 1000 or 10 K

Direct Value:• Resistors with larger physical size are often printed the value directly on their body

Standard Resistor Values
Electronic Industries Association (EIA) standard E24:
Standard E24 specifies resistors based on 5% tolerance (often resistor of this category has 2% tolerance now a days due to advancement of manufacturing techniques)
100 110 120 130 150 160 180 200
220 240 270 300 330 360 390 430
470 510 560 620 680 750 820 910
Standard Resistor values =
× 10M Ohms
(Where M can be any integer, positive or negative)
