Resistors are commonly found elements in electrical networks and circuits. These components are used to control electric current flow within electrical parts and circuit boards. One of the most common types of resistors is known as the wirewound resistor. Wirewound resistors are produced by winding metal wire around a plastic, fiberglass or ceramic core. Typically, this metal wire is comprised of nichromea nickel-chromium wire.
Optimized circuit designs often include wirewound resistors where precision is important. Wirewound resistors have tight resistance tolerances and are typically very stable. Since these resistor types can maintain their precision over time, they are extremely popular in electrical components. They are comprised of very stable materials and are very reliable and rugged. Modern circuits typically use wirewound resistors for this reason.
