What You Need To Know About Wirewound Resistors
Today, there are multiple electronic instrumentations and applications that demand power resistors. Some of these instrumentations demand precision resistors and these are categorized under wirewound resistors. Therefore, through this article, you will garner some fundamental facts about wirewound resistors and why a wirewound resistor company capitalizes on precision when manufacturing them.
To begin with, there is need for you to understand what wire wound resistors are. Generally, this is a type of a passive component through which wounded wires or rather metal wires are used to restrict power or electric current to a given level. When making the wire wound resistors, metal wires are zigzagged around a metal core. Generally, the metal wires are the electric current resistance and the core is always the non-conductive material. Basically, there are two main materials used for the metal wires and these are manganin and Nichrome. The treason why a power resistor company will use either of these two materials is due to their compatibleness with high temperatures. In other words, they tend to operate tremendously availing irrefutable resistance even in high temperatures. When it comes to the core, a plastic, fiberglass or a ceramic material is used as these are the best non-conductive materials. You'll want to be familiar with wirewound resistors.
There is need for the wounded or rather the zigzagged wire to be covered with an insulating material. The insulating material will always help dispense outside heat whenever the resistor is mounted on the application or the electronic equipment. In most cases, the insulating material is vitreous enamel and it performs tremendously when it comes to blocking the outside heat. Where the external heat is prevented, the resistor tends to embrace a higher stability. As a result, the resistor is able to perform appropriately in high temperatures as there is no external heat penetrating to the wirewound resistors. Do check out great high power resistors sources.
There are two types of wirewound resistors and these are precision wirewound resistors and power wirewound resistors. Basically, precision wirewound resistors are the resistors ideal for low temperatures and they are also ideal where accuracy is not negotiable. The power wirewound resistors are ideal for high temperatures and they are also known or referred to as the non-inductive wire wound resistors.
There are multiple and tremendous benefits of using wire wound resistors. The first benefit is the low cost for these resistors and this is something that many people look for; affordability. The resistors are overly accurate and their high level of precision matters great a deal and enhances the functionality of the electronic applications necessitating these resistors. Finally, wire wound resistors have high stability and wide resistance range and this is a plus.
