What is a conductive resistor?
The wire resistor is an electronic component that provides a predetermined amount of resistance to electric flow in the circuit. The structure of the wire resistance is usually a specific length of the resistance metal wire that is wound around a form of a type. The ability to control the exact amount of resistance wire used in the device during the production process allows it to be made with a very accurate amount of resistance. The wire resistor will find common use not only as an accurate resistor, but also in applications that require the component to be able to resist and function properly in a high -temperature environment.
A common resistor is usually constructed from a carbon film or composite material that provides resistance to the electrical voltage in a given range, referred to as the tolerance of the device. While a normal resistor may have a tolerance of five to 20 percent of its value, the wire resistor is a much more accurate device. Using a resistive metal wire made of nickel and chrome alloy called nothingThe thunder, range of tolerance of a typical wire resister is usually one percent or less evaluated. For special applications, it can be made with tolerances of up to 1/100 one percent.
The production of a typical guide resistor includes the winding of a resistance wire around the mold commonly made of ceramic, glass fiber or plastic, which is usually in the shape of a tube or solid cylinder. The metal cap with a metal lead connected to the solder finished device on the circuit board is then placed over each end of the wire shape and each end of the resistance wire is burned to one of the caps. The body of the device is then covered with a non -conductive color, enamel or plastic.
wire resistors are useful in high temperature applications because their functional components are made of sewer. In this case, the wires of the resistors are welded to the end cap or metal rings that serve the same purpose. ClashIt is then covered with non -conductive material resistant to temperature and closed in an aluminum or ceramic body.
Since the resistance wire in the wire resistors is in the shape of coils around their molds, they can create a phenomenon called inductance, which is generating an electromagnetic field that resists voltage. Although these fields do not affect the wire resistors themselves, other devices in the electrical circuit may disrupt. Special low noise resisters are produced to face inductive effect. These resistors have either a resistance wire wound in several directions, in special samples or around flat molds, which significantly reduces the electromagnetic fields that the device is able to create.
