Details of the colour code system can be found here in the technical data section. If you have a resistor with a gold or silver band on one end, you have a 5% or 10% tolerance resistor. range values. Most resistors have 4 bands: The first band gives the first digit. The tolerances defined in ISO 286-1 are applicable to size range from 0 mm to 3150 mm but there are exceptional cases defined in the standard which depend on tolerance selection. In this system, the marking exists out of three digits: 2 numbers to indicate the resistor value and 1 letter for the multiplier. How to identify a 5 band resistor? The resistor will visually show your band color choices and display the value of the resistor above. This tool is used to calculate power, current, voltage or resistance. Clicking Calculate R1 and R2 will find the optimum pair of resistors from the selected range of preferred values, for a given V in and V out. 4R7K = 4.7 Ω +- 10% You can select the colors of the corresponding bands by clicking on them in the table. This is a simple online calculator for color band resistor marking, inductor color band marking, ceramic or tantalum capacitor 3 digit marking and SMD resistor 3-digit, 4-digit, 10%, 5%, 2% and EIA-96 (E96) 1% tolerance code marking. Use this website to convert resistor color codes into resistor ohm value and tolerance. Different codes are used for wire leads on devices such as transformers or in building wiring. This calculator will select the closest standard resistor value, from 1% 5% or 10% standard EIA values, calculates the error, and prints out a table of the standard values for the given tolerance. and max. Four Band Resistor Color Code Calculator. This calculator is designed to display a typical carbon film resistor. For example, for the three band resistor color codes shown (brown, black and red), the resistance value according to the table would be:.. 0 x (100) = 1000Ω. How do you calculate resistor color code? Resistor Colour Code Calculator. Online calculator for tolerances. Resistor Calculator. The site will find the best pair of standard-value resistors from the tolerance class that you selected. Resistor Color Code Calculator decodes value and tolerance of 4 and 5 band resistors. For example, a resistor has the following coloured markings; Yellow Violet Red = 4 7 2 = 4 7 x 102 = 4700Ω or 4k7 Ohm. Resistor having only single black band is called as zero-ohm resistor. The color code for tolerance is as follows: brown - 1% . This calculator will help you identify the value, tolerance and temperature coefficient of a color coded resistor by simply selecting the bands colors. - Resistors never start with a metallic band on the left. It will also calculate the minimum and maximum values based on the tolerance ratio. To convert from value to colours: Select the resistor type (4 or 5 bands) using the radio buttons. The resistor color code calculator makes it easy to identify and select resistance and tolerance values for 4, 5, and 6 band through hole resistors. Hover above the tolerance for min. You may click on any of the drop down box values and the color band display will change to the appropriate bands. In other words, the resistor tolerance is the amount by which the resistance of a resistor may vary from its stated value. Resistor Series. Tolerance is indicated as. This video will teach you how to find the acceptable range of resistance for a resistor. Resistor Color Code calculator - calculate corresponding value of a given resistor color marking.
