Hence, they are replaced with grey and yellow color bands. The gold and silver bands are prone to misconceptions of true colors in a resistor. It is used as an interconnection between two joints. This resistor comes with a single black band used to connect the traces on a Printed Circuit Board (PCB). Typically, a 4-band resistor comes with a reliability band. This band is not found in commercial electronics. To meet the military specification resistors often manufactured with reliability band. Now place the first two bands as the numeric value and third band as a multiplier (10 5). For example, to calculate 1.2MΩ, the resistor shows Brown Red Green colors (read from left side to right).
#3 band resistor color code calculator how to
To understand how to read the resistor color code for 3 /4/5/6 band resistors you can use this color chart.įrom the above chart, each color band on the resistor represents a number. Resistor Color Code Chart – 3 band 4 band 5 band and 6 band The variation of resistance is constant to temperature. The higher ppm value indicates that a resistor can withstand the higher or lower temperature. The 6-band resistor has a special property of temperature coefficient of resistance represented in ppm/Kelvin. In addition to this the 4 band, 5 band, and 6 band resistors have tolerance value ranging from ☐.10 to ☑0. The multiplier value is multiplied with the significant digit number (one, two, or three digits) to get the desired resistance value. For 5 band and 6 band resistors, the first 3 digits indicate significant numbers. This number can be used as the first significant digit and second significant digit for 3 band and 4 band. To know, how to find color code, each color indicates a number starting from 0 to 9. The color code chart shows the 3 bands, 4 band, 5 band, and 6 band resistor strips. Whereas, the 4 band, 5 band, and 6 band resistors have an extra band known as tolerance. The three bands can be selected to know the resistor value. The 3-band resistor has three colors with multiplier and no tolerance. The Carbon composition resistors have 3 to 6 resistor color bands.
For example, a 4.7K ohm resistor is shown as 4K7.
It uses letter 'R' for ohms, 'K' for Kilo ohms, and 'M' for Megaohms.
#3 band resistor color code calculator update
You may change a value by again clicking on the band values from any of the three bands but be sure to click on Calculate Values after each selection to update the correct information of resistor value and color band text representation.Resistors use the BS1852 (British standard) coding standard for value representation. This calculator does not consider the 4th Band, tolerance, since it would not change the calculation. After selecting a value from all three bands, click on Calculate Values and the resistor's value is calculated and will appear as well as a text representation of the three bands. Immediately to the left of the Calculate Values button below the three bands, there are three boxes that upon selection of a color from the bands, an identifying number and color will correspond in appearance. To use the calculator, select a value from the vertical group of Color Band 1, from Color Band 2 and from Color Band 3. This table names (as well as shows) the colors and the values.
For those in the electronics business that are color blind (as I am), working with resistors and color coded capacitors can be difficult. For operational and other information, and for those unable to use the calculator because of browser limitations, there is a table below the calculator and additional information below the table. This converter requires the use of Javascript enabled and capable browsers.
