Power resistors are among the most useful parts in any electrical model these days because they are the ones that control the power in order to protect the models from burning. If you are creating a board, for instance, you might need to limit the amount of power that can be supplied to your overall model by using a high power resistor most especially if the current is too high. Yet most of the people these days don’t know what are the things that they need to consider when looking for the perfect power resistor that they can ever get according to what is needed with the project that they are working with. It can be risky to get the wrong type of power resistor according to the specific use that you will need it for therefore, you really have to be careful when choosing. In order to help you determine what is the perfect power resistor to get for your specific needs, this article will provide you with a simple guide in choosing.
One of the most popular types of power resistor these days is the current sense resistor or what is commonly known as the current shunt resistor or just the shunt resistor. This type of resistor is so popular because it is widely used for the expanding of the current measurement range which is why it has gained its name. It is also considered as the current sense resistor because it can also be used for detecting circuit current which is why the word “sense” can also be used to refer it. You can use this type of power resistor for smartphones and all other portable devices because its features provide for the best functionality in such purpose. Larger versions of this type of power resistor can also be used in assembling automotive because they can really be useful for such purpose.
If you are looking for another type of power resistor, there is also this type called the wirewound resistor. In order to provide the best resistance for your specific use, this type of resistor uses a high resistivity wire that is then wrapped in a reliable coil covering. The thing about this type of power resistor is that it also has different components depending on the type of purpose that you intend it to use for. The different types of power resistors include the precision wirewound, the power wirewound, the potentiometer wirewound and many others. There is also this custom wirewound resistor that you can adjust according to the purpose that you wish to use it for.
