Wirewound resistors refer to electrical passive components that are designed to limit the flow of electricity in a circuit. These types of resistors have a conductive wire made of metal alloys that remain wound around a non-conductive core. The conductive wire of a wirewound resistor is typically made of silver alloys, copper alloys, nickel chromium alloys, iron chromium alloys, or iron chromium aluminium alloys.
Types of wirewound resistors
Wirewound resistors are primarily available in two types. These are:
Power wirewound resistors
These types of wirewound resistors are non-inductive and operate at higher temperatures. Naturally, they are most suitable for high-power applications.
Precision wirewound resistors
These types of wirewound resistors are designed for operation at low temperatures but offer high accuracy. They are most suited for use as a precision resistor in different instrumentations.
Wirewound resistors have extensive uses, particularly in applications that require high power. As such, they are most commonly used in:
