Again, we check the resistor color code chart for red, violet and yellow, and the first, second and third bands give the significant digits of 2,7 and 4 respectively. The fourth band is black, giving a multiplier value of 10 0. Hence, we will get a resistance value of 274 × 10 0 = 274Ω resistor conversions (see Resistor Conversion Chart).

Standard Resistor Tables (Based on EIA Preferred Values) Where electronics engineers discover the latest tools. Hardware design made eas SMD resistor sizes. The shape and size of surface mount resistors are standardized, most manufacturers use the JEDEC standards. The size of SMD resistors is indicated by a numerical code, such as 0603. This code contains the width and height of the package. So in the example of 0603 Imperial code, this indicates a length of 0.060 and a width. The Resistor Color Code Calculator identifies the value and tolerance of a color coded resistor given its bands colors. Supports resistors with 3, 4, 5 and 6 bands These resistors have two bands for the resistance value, one multiplier and one tolerance band. In the example on the left these bands are green, blue, red and gold. By using the color code chart, one finds that green stands for 5 and blue for 6. The value is thus 56·100 =5600 Ω. The golden band means that the resistor has a tolerance of 5% ** Use the Resistor Color Code Chart (below) to understand how to use the color code system**.

Color banded axial lead resistors with 4 or 5 bands are supported There are two main types of resistors: Standard resistors have four color bands. Three of the bands tell you the nominal value, which means the value the resistor was designed to have.The fourth band tells you the tolerance of the resistor, which indicates how far off the nominal value the actual resistance could be. (The manufacturing process isn't perfect, so most resistors are a little off.
