What are Wirewound Resistors?
A wirewound resistor is an electrical passive device that limits or restricts current flow in a circuit. Wirewound resistors are constructed using a conductive wire. The conductive wire is then wound around a non-conductive core. The conductive wire can be made of varying alloys and thickness to control the resistance value. Wirewound resistors are typically used in high power and industrial applications such as circuit breakers and fuses.
Wirewound Construction
Savol produces over 20 different series in wirewound construction. which can be chosen based on mounting, application, and resistance range. Different types of wirewound resistors include Precision, Axial, Tubular, Surfacemount, and Adjustable, which all have good stability and resistance range, and are produced in many wattage sizes. The higher wattage wire wound resistors are used in High Current/Braking applications.

Wirewound Fixed Resistor

In the beginning of electronic and electrical circuits history, resistor means Wirewound resistors, there were no other alternative as today.
Wirewound resistors are one of the first practical resistors used since from the beginning. Wirewound resistors have longer life compared to other types.

A wire wound resistor is an electrical passive component that limits current. The resistive element exists out of an insulated metallic wire that is winded around a core of non-conductive material. The wire material has a high resistivity, and is usually made of an alloy such as Nickel-chromium (Nichrome) or a copper-nickel-manganese alloy called Manganin. Common core materials include ceramic, plastic and glass. Wire wound resistors are the oldest type of resistors that are still manufactured today. They can be produced very accurate, and have excellent properties for low resistance values and high power ratings.

1.Precision: The important characteristics of Wirewound resistors is its precision. They can have very tight resistance tolerances say 0.005% is commonly achieved.
2.Stability: Next is its stability, they are stable (15-50ppm/yr) maintaining their precision over time because they are made with stable materials

3.TCR (Temperature Coefficient of Resistance) is low (<10ppm/°C) and can be controlled by selecting special wire alloys. (Usually, you need the lowest TCR, but a higher TCR has special interest in some applications.

Features:

1.Superior heat resistance.

2.Superior pulse resistance.

3.High reliability.

4.Can offer noninductive type.

5.Low temperature coefficient, low noise.
