This calculator will help you identify the value, tolerance and temperature coefficient of a color coded resistor by simply selecting the bands colors. It will also calculate the minimum and maximum values based on the tolerance ratio.

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.

This resistor calculator converts the ohm value and tolerance based on resistor color codes and determines the resistances of resistors in parallel or series.

Free online resistor color code calculator. Easily decode 4, 5, and 6 band resistors. Get instant resistance values, tolerance, and temperature coefficients.

Our Resistor Color Code Calculator is a handy tool for reading carbon-composition resistors, whether it's a 4 band, 5 band, or 6 band type. To use this tool, simply click on a particular color and number and watch how the actual bands on the resistor illustration change.

2025年1月11日 · Find out the resistance value with this resistor color code calculator! Just choose the resistor type, select the colors, and the tool will display the resistance, tolerance, and range on the spot.

The calculator above will display the value, the tolerance and performs a simple check to verify if the calculated resistance matches one of the EIA standard values. Select the first 3 or 4 bands for 20%, 10% or 5% resistors and all 5 bands for precision (2% or less), 5-band resistors.

Our free resistor color code calculator makes it even simpler. This versatile tool not only allows users to determine the value of a resistor based on the color code but also find the color codes for a 4 and 5 band resistor.

Find the value and tolerance of a 4 band, 5 band, or 6 band resistor with our Resistor Color Code calculator or download our color code PDF for reference!

The resistor color code calculator will determine the resistance value in ohms of a resistor based on the color code of the resistor.
