Resistors come with different rated resistances, and 470 ohms is one of the ratings. After doing a deep analysis of your circuit design, chances are you might have decided that 470 Ohms is the perfect fit for the job. If this is the case, you should go further to get all the relevant information about this resistor. One of the most important information is the color code.

The colors on your resistor are more than just for creating visual appeal and enhancement.  They are used for representing key specifications that determine the performance of the resistor.  You can use the color bands to find the exact resistance value of the resistor.

In this article, we are going to discuss what you should know about the color codes for the  470 ohm resistors. You will understand what each color band of the resistor represents and how to use each band to calculate the exact value of the resistor, among other key parameters of the resistor.

Overview of 470-ohm resistors

Before we even look at the color codes, let's have a brief understanding of what a 470 ohms resistor is. Well, this is a type of resistor that is designed to give 470 ohms of resistance when used in an electric circuit. It has two terminals on both ends for easy connection to the rest of the circuit

470 Ohms resistor is relevant in electronic applications that require the exact resistance to run and operate efficiently. Using its defined resistance value, it will limit or regulate the flow of electric current in a circuit. This way, devices and components that are connected to the circuit will be fully protected from the excess current.

Other than limiting current, this resistor is also used for adjusting the levels of signals in a circuit. If the incoming signals are extremely high, it will lower them to a value that can be handled by the devices. This feature is important especially when you want to get quality and regulated signals from a device.

470 Ohm resistor color code

 A typical 470 Ohm resistor has different color bands on its surface. However, the bands are not the same in all the resistors. The variance depends on the tolerance of the resistor and in some cases the thermal sensitivity of the specific 470 Ohm resistor.

When it comes to color code analysis, we have to consider two main options; 4-band 470 Ohm resistor and 5-band 470 Ohm resistor. There is a slight difference in the color codes of these two resistor options.

For a 4-band 470 Ohm resistor, the color bands are arranged as follows:

· Yellow has a value of 5

· Violet has a value of 0

· Brown  has a value of 10 and represents the multiplier

· Gold is the tolerance value and  is ±5%

When you do the calculations, the total resistance value will sum up to around 470 Ohms.  The tolerance value is expected to have an impact on the final figures that you will get from the resistor.

If you are using a 6-band 470 Ohm resistor, the extra band will represent the temperature coefficient value of the resistor.  It defines how the resistor reacts to the temperature changes.

Once you know the exact value of each color band, you will be able to calculate the exact resistance of your resistor.  If you are not sure about the value of each color band, you can still calculate the resistance value by using different color code calculators online.

Uses of 470 Ohm resistor

Are you contemplating using 470 Ohm resistors but not sure whether they are suitable for your application? Here are some of the most common uses of 470 Ohm resistors in the world of electronics:

· Current regulation: This is the primary role of most resistors. They are designed to regulate the amount of electric current that goes through the circuit. This is usually done by placing the resistor between the current source and the component that you want to protect.

· Volage division: Here, 470 Ohm resistors are used for dividing the total input voltage into different classes or divisions. This application comes in handy when you have different devices in a circuit and each has a specific operating voltage.

· Signal conditioning: Analog circuits use resistors to control the quality of signals that are coming out of the circuit.

· Impedance matching:  470 Ohm resistors are used in radio frequency (RF) circuits to perform the impedance matching of the radio frequencies.  This is done through current regulation which in turn affects the frequency signals.

Buying 470 Ohm resistors

Equipped with the right information about color codes and even uses, the next step entails buying 470 Ohm resistors.
