How to Choose the Best Type of Power Resistor
Various types of electrical applications need high power resistors. Some electronics need low power resistors while some need high power resistors. Low power resistors can be operated as long as it has a watt. One watt or more is what is needed for you to operate high power resistors. Power supplies, power conversions, dynamic brakes, amplifiers and heaters are just some applications that utilizes high power resistors. Some things that you need to take note of before purchasing a power resistor.
How do you define a power resistor? As soon as you hear the term power resistor, it will immediately lead you to connect it as an electrical factor that is made out of two terminals. The electric current that these two terminals are able to produce is equal to the voltage that it generates. A resistor is what you call the current that passes through these terminals. Voltage is what you call the power which enables the current to flow into the circuits that are given. The one that will be measured in Ohms is called resistance, which controls the flow of the current. These power resistors are able to aid in controlling the flow of current. In order for you electronic device to function properly, you should have a regulated flow of current.
Since power resistors have a lot of types, you will not have to worry about a wide variety of options to choose from. Take for example, there are cases wherein a carbon resistor is utilized by putting together the lead to a rod or a bar of carbon material. Nonetheless, carbon resistors are not one to relay on in dissolving more power and it is also unable to produce a lot of resistance tolerance. A representative of a power resistors company or an expert in power resistors is one who should be able to help you find the right type of power resistor that would best fit your electronic application. You can save a good amount of money if you can utilize a carbon resistor to meet your needs.
Although it might be best for you to consider a power resistor since they are made of metal films or oxides that can be able to offer you better tolerance. Wirewound resistor is the most common for this type of resistor which is comparable to other power resistors since it is capable of dissipating larger power levels. To add to this, since these wirewound resistors are available, it is easy to control temperature better. A wirewound resistor is the best power resistor that you could acquire if you are required to deliver precision with your electronic device. With this said, you don’t have to ask why the latest circuits are made out of wirewound resistors.
