100k resistor is quite common in the world of electronics. Rated 100,000 Ω, this is a type of resistor whose resistance value will be of great importance on any serious electronic application, especially if you expect the circuit to handle some significant level of power.

Regardless of the levels of your expertise in the matters of electronics, it is always important to have full information about resistors and color codes. Not only will this information help you make the right selection but also assist in the proper implementation of the circuit

In this article, our focus will be on the 100k resistor color code. You will understand the different color bands that are used on this resistor and what they stand for. You will also get to know the difference between different color bands of 100k ohm resistor codes.

What is a 100k ohm resistor?

A 100K  ohm resistor is a passive electronic component whose resistance value is 100,000 Ω. It will offer 100 ohms of resistance to any circuit that is connected to it.

100K  ohms is always considered among the pinnacle or topmost threshold of resistance in most electric circuits. This implies that it is mainly used in high-power applications thanks to its high resistance value.

Despite offering high resistance, it is still a compact passive electronic device. It is small and can easily fit into small devices and integrated circuits. The size also makes it more practical to be used in a wide range of applications, both low-power and high-power applications.

100k ohm resistors are commonly used as bleeder resistors. This means that they are connected in parallel with high-voltage power supply units, which are used for discharging electric charge stored in the capacitor whenever the power source has been turned off.

 This explains why you are likely to find this resistor alongside a capacitor.  The main function of a resistor in such an application is to play a protective role. They protect the circuit from the excess current that is discharged from the capacitor.

Of course, there are many other applications of 100K ohm resistors in many different applications. Once you design your circuit, you will be in a perfect position to decide the resistance value of your resistor. If it is 100k ohms, you will define its purpose in the circuit.

100K resistor color code

The first thing that you will notice once you see a 100k resistor is the different color bands on its surface.

The arrangement of these bands on a resistor is based on the industry-standard color codes. Each color band represents a particular feature or value about the resistor.

However, you should not pay attention to the overall body color of the resistor as it does not hold a significant value.

Most 100k  ohm resistors in the market have different numbers of bands. Some have three bands, others four while others have up to five bands. Regardless of the numbers, you should have a deep understanding of what each color band stands for.

In a 4-band resistor, the first three bands give the resistor's nominal value. The fourth or last band gives information about the tolerance value of the resistor.

In case it is a 5-band resistor, the first gives the resistance's nominal value while the fifth color band signifies the tolerance value of the resistor.

Some 100k resistors have up to six color bands. The extra band in such a resistor signifies the temperature coefficient value of the resistor. This is all about the sensitivity of the resistor in response to different temperature variations.

How to read  100k resistor color code

So, how do I read and interpret the color codes on resistors? Since there are different types of 100k ohm resistors based on the number of color bands, will need a different approach to read the color codes. Here  is a complete guide for reading 100,000 Ω resistors color codes:

4 band 100k ohm resistor

· The first band is brown in color and represents the resistance value of the resistor. Its value is 1.

· The second color band is black and also stands for the resistance value. It adds 0 to the first value, meaning that the first and second bands will give you a value of 10.

· The third band is yellow and stands for the multiplier

· The fourth band is colored gold and stands for the tolerance levels.

You can use the same reading tactic for the 5-band and 6-band resistors only that there could be some slight difference on the last color bands of each resistor.

For the 5-band resistor, the first three bands represent the value of resistance while the fourth band represents the multiplier. The fifth band is for tolerance.

In case you are using a 6-band 100k ohms resistor, the sixth band represents the coefficient temperature of the resistor and it has no specific color.

Final thoughts

Equipped with the right information about 100k ohm resistor color codes, I am sure that you are in a perfect place to make the right decision when it comes to buying and using these resistors.

When it comes to buying, you can use the color code to analyze the actual resistance value of your resistor. The same applies when it comes to implementing the resistor into your electric circuit. You will design the circuit that will make proper use of your 100,000 Ω resistor.

Beyond the numbers, you should also pay attention to the quality of resistors that you want to buy.  The right quality will be reliable and deliver the desired performance. For example, it will have a narrow tolerance level.
