When selecting a resistor, choose a value as close as possible to the required resistance. Standard resistor values are available in a logarithmic series known as the E-series, such as E12, E24, or E96. It's usually easier to find resistors with values from the E12 or E24 series, which are more common and readily available. Power Rating an SMD resistor with a marking of 0, 00, 000 or 0000 is a jumper (a zero-ohm link). a chip resistor marked with the standard 3 digit code and a short bar below the marking denotes a precision (1% or less) resistor with a value taken from the E24 series (these values are usually reserved for 5% resistors). For example: 122 = 1.2kΩ 1%. Some The following is a long list of all E24 series resistors - from 0.1 ohm to 10 M ohms - with the shorthand notation, tolerance range and color code. The 4th band is always gold (5% tolerance) for the E24 series. A 5th band may be present, indicating the reliability or the temperature coefficient. Standard values of nominal resistance are taken from the E24 series for resistors with a tolerance of ±5%, and E24+E96 series for resistors with a tolerance of ±1%. The values of the E24 / E96 series are in accordance with "IEC publication 60063" 3-Digits Marking (1% : 0603) Resistor finder. Finds a combination of two series or parallel connected resistors for a custom value. Returns a list of the best values found. Example 1: Must calculate the combination of 1% resistors to produce a resistance of 66 kilo-ohms. You may use one of the following SI prefix after a value: p=pico, n=nano, u=micro, m=milli, k=kilo, M So, for a 560 ohm, 5% resistor the color stripes will be green, blue, brown and gold. Green and blue are the first significant digits (56); brown is the multiplier (10 1 = 10) and gold is the tolerance (5%). 56 x 10 = 560Ω. If the 3rd band would be red instead of brown, the multiplier would be (10 2 = 100) instead of 10 and the resistor value rKxR.
