What makes a wirewound resistor a wire wound resistor?
The wirewound resistors are formed by twisting the resistance wire around the insulating frame. Resistance wire is generally made with a certain resistivity of nickel chromium, manganese and other alloys made of copper.
Can a wire wound resistor be used as a heat sink?
Wirewound resistors come in a variety of packages and many are particularly suited for power resistor applications – some are contained within ceramic packages, while others are available within metallic packages that can be bolted to a metallic chassis or other forms of heat sink.
What kind of wire is used to make a resistor?
The resistor is constructed from resistance wire that is wound around a central core or former, that is usually made of ceramic. Basic construction concept of a wire wound resistor. Once wound, end caps are pressed onto the core and the resistance wire is welded to them to make proper contact.
Why do you need tight tolerance wire wound resistors?
If tight tolerance wire wound resistors are required, then the resistance wire chosen can have a lower resistance making the wire longer, and enabling its length to be cut more accurately as a proportion of the total length. If necessary the resistance can be trimmed on an individual basis.
