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.

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.

2016年7月4日 · The resistor color code (color bands) on your resistor tells you what value the resistor has. There are usually 4 or 5 bands. Use our simple resistor color code calculator tool below to easily find the value of any resistor.

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.

Resistors with 6 bands are basically 5-band resistors with an additional ring indicating the reliability or the temperature coefficient. The resistor has only 3 bands. You don't have to enter the 4th band, as 20% resistors don't have a tolerance ring. They will be calculated using the 4 band rule (digit, digit, multiplier).

2025年1月11日 · Just choose how many bands your resistor has – 4, 5, or 6, select the colors, and in the blink of an eye, you'll get the resistance with tolerance, range, and temperature coefficient value (if you've chosen 6 band resistor color code).

The Resistor Color Code Calculator will calculate the resistance value in Ohms (Ω) for 4-band and 5-band resistors based on the color code on the resistor. Choose resistor color code to calculate resistance value. Note: Tolerance values in % of full resistance range. Resistance values can be calculated from a 4-band resistor color code as follows:

2024年8月13日 · The electrical color code resistor chart below displays the color bands for 3-band, 4-band, 5-band, and 6-band resistors. A 5-band resistor is more precise than a 4-band resistor due to its third significant digit. Additionally, a 6-band resistor includes a 6th band, which represents the temperature coefficient.

The number of bands present in a resistor varies from three to six. The first two bands indicate the resistance value and the third band serves as a multiplier. In this piece of article, let us discuss how to read resistor colour codes, look at an example and learn a mnemonic to remember the number sequence. Uses of Resistor

With these color bands, we can identify the resistive value and its percentage tolerance of a resistor. For large power resistors, the resistor body is big enough to print the resistance value, tolerance, and wattage rating on them.
