Things You Need to Know About Power Resistors Before Buying Some
One of the things that you need to know about power resistors is that they are used for a variety of electronics applications. If some electronics applications require low power resistors, you also have those that need high power resistors. For low power resistors, less than a watt is needed. On the other hand, with high power resistors, you will be needing one watt or more. Needing high power resistors is associated with the use of amplifiers, power supplies, heaters, dynamic brakes, and power conversion. Here you will read the basics of power resistors and more.
Now, what is the meaning of power resistors? The first thing that you need to know about power resistors is that they come with two terminals as an electrical component. These terminals produce both voltage and electrical current. What passes through the current is what you call as the resistor. Voltage is the power that is required for the current to flow through the circuit that is given. On the other hand, the one that is responsible in controlling the current flow is resistance that can be measured in Ohms. Power resistors help to control the flow of current. Current flow must be controlled to ensure that your electrical component or part will be able to function properly.
Now, when it comes to these power resistors, you can choose from different types of them. A carbon resistor, for instance, is one example of a resistor that has leads attached to a bar or rod of carbon material. And yet, carbon resistors are not able to produce very minimal resistance tolerances as well as be able to dissolve a lot of power. One way for you to find out what type of power resistor will work best for the kind of electronics application that you have in mind is to speak with an expert in power resistors like a representative of a power resistors company. When after assessing your needs a carbon resistor will do, you can save a good amount of your money.
You might want to consider getting power resistors, though, that are made of metal films or oxides if you are looking for something that will offer you better tolerances. For this type of resistor, the most common is the wirewound resistor that is capable of dissipating larger power levels compared with other power resistors. In addition, you can expect better and easier temperature control capabilities with these wirewound resistors. When you are required to deliver precision with your electronic device, then a wirewound resistor is the best power resistor for you. You will not be surprised anymore why this particular power resistor is the one that is being employed in the application of the latest circuits.
Whichever power resistor you choose, just see to it that you take note of the required top voltage rating, power rating, tolerance, and resistance of the power resistor of your choice.
