Among the most versatile resistors in the electronic components market are the  500 ohms resistors Just as the name suggests, these resistors are designed and manufactured to offer electric resistance of 500 ohms. Perhaps this is among the key reasons behind its popularity as it's compatible with most modern applications.

500  Ohm resistors come in a variety of shapes, physical sizes, and even color codes.  In this guide,  we are going to learn all the essentials of 500 Ohm resistors. We will discuss what you should know about the 500 Ohm resistor color codes and the impact that they have when it comes to integrating the resistors into electric circuits. You will also learn a couple of other things to look at when buying 500-ohm resistors.

What is a 500 ohm resistor?

 A 500 ohm resistor is just like any other type of resistor. It has two terminals and is designed to provide electrical resistance to a circuit. The two terminals are directly connected to a circuit, meaning that the resistor will also be part and parcel of the circuit.

The key difference with other resistors is this one offers   500 ohms of electric resistance. With this value, it means that the resistor will cause a significant voltage drop across the circuit.

How do I know that the resistor has 500 ohms of resistance?  There are many ways of finding this information and one of the methods is by using color codes. This is usually an ideal method especially when the exact resistance value is not printed on the surface of the resistor.

Key features of 500 ohm resistors

 Before we look at the 500 ohm resistor color codes, Let’s highlight the key features of this resistor. By knowing the features, you will determine the suitability and practicality of the resistor in your application.

· Resistance: The resistor has a rated resistance of 500 ohms. This means that it will offer 500 ohms of resistance to any circuit in which it will be integrated. This resistance is responsible for regulating the flow of electric current in a circuit.

· Tolerance: Tolerance refers to the accuracy of a 500 ohm resistor when in operation.  The value tends to vary from one resistor to another depending on the manufacturer.  It is usually defined in terms of percentage and may vary from +-1% to +-10%. You can also use the color code to know the exact tolerance of your 500 ohms resistor.

· Power rating: This refers to the power that is dissipated from the resistor when it is in operation.  In most cases, power is dissipated in the form of heat. In most cases, power ratings tend to vary from one  500 ohm resistor to another. The lower the rating the better.

· Temperature coefficient: This refers to the relationship between temperature changes and resistance value. It is usually calibrated in terms of parts per million per degree Celsius.

· Reliability: Most 500 ohm resistors in the market have high levels of reliability. They are designed to offer the required resistance without failing. However, you should still be extra keen when it comes to analyzing the reliability of resistors as it may vary from one brand.

· Stability: When it comes to resistors, stability refers to the ability of a resistor to retain its resistance constantly despite the variation of the external changes. The best 500 ohm resistors in the market are highly stable. But again, you should be keen on where you buy.

· Color codes: 500 ohm resistors come in different color codes. The most notable ones are black, green, brown, and gold. As we will look in the next section, each color code stands for something.

500 om resistor color codes

As we have mentioned, color code is one of the key features of 500 ohm resistors. These codes are  mainly used for representing the resistance values of the resistors.

A 4-band 500-ohm resistor will have the following color codes:

· Green (5)

· Brown (1)

· Black (0)

· Gold (+-5)

In case it is a 5 band 500 ohm resistor,  the color codes will be as follows:

· Green (5)

· Black (0)

· Black (0)

· Brown (1)

·  Brown (+-1)

The above two examples are for the four-band and five-band resistors. However, you may come across resistors that have six bands. They are also known as precision resistors and have six color bands. That extra sixth band represents the temperature coefficient of the resistor.

Applications of 500 ohm resistors

Here are some of the most common uses of 500 ohm resistors:

· Current regulation/limiting: This is the most common application of resistors. They limit or regulate high electric current from reaching specific sections and components of electric circuits. In such applications, resistors play a protective role.

· Voltage division: This is quite common in series circuits whereby resistors are used for  breaking down circuits into different voltages depending on the components and loads.

· Biasing: 500-ohm resistors bias voltages that are used for devices such as operational amplifiers and transistors.

· Signal conditioning: This is quite common in analog circuits where resistors are used  by filters,  and oscillators to generate desired electric signals.

Conclusion

Having the right information about the 500 ohm resistor color codes is essential for your project.  The information will help you make necessary estimations and calculations about voltage regulation on the electric circuit.

 This information is also crucial when it comes to the purchasing of the resistors. Not only will you know the exact resistance of your resistors but also you will have prior information on how to read the codes.
