100k ohm resistor color code with 3 4 5 and 6 bands

100k Ohm carbon film resistor is a popular resistor in electrical circuits. It can be available with three, four, five or six bands. These bands have different colors which are known as the color code. To know the resistance value of the resistor, we should know how to read the color code. The resistor color code for different colors is available in the post Resistor color code chart. In this post, I am going to explain how to read 100k ohm resistor color code with 3, 4, 5 and 6 bands.

A three-band 100k resistor has the first two digits 1 and 0 and the multiplier is 104. Then the color code for 3 bands 100k ohm resistor is 104M with the bands of colors Brown, Black and YellowM refers to 20% tolerance i.e. no fourth band.

So, the color coding of 100k ohm resistor with 3 bands is Brown, Black and Yellow (104M).

4 Bands 100k resistor color coding

If the tolerance is 5% then there will be the fourth band of golden color which is coded as J. First three bands will remain the same as that of three-band 100k resistor. Then the color code of 100k resistor with 4 bands will be 104J. The colors of the bands are Brown, Black, Yellow and Golden.

A five band 100k resistor has the first three digits as 1, 0 and 0 respectively and the multiplier is 1000. If the tolerance of 10% then there will be a fifth band of color Silver. Then, the color code for 100k ohm resistor with 5 bands is 1003K with colors of bands as Brown, Black, Black, Orange and Silver.

If the temperature coefficient of the resistor is 0.5 then there will be a sixth band of color Green which is coded as 5. Other bands will remain the same as that of five-band 100k ohm resistor. So, the color code of 6 band 100k resistor will be 1003K5 with bands of colors Brown, Black, Black, Orange, Silver and Green.
