It is particularly suitable for precision circuits in the automotive industry. Additionally, the resistor can be used in areas where low noise and high stability are preferred.

Working Principle

A through hole resistor is a resistance device that consists of two conductive materials that are isolated from each other. In the RWR89S3R09DRS70, the two materials are copper-nickel coating and a carbon type element. The resistor works by reducing the flow of electrons that travel from one material to another. The electrons are slowed down by the resistance produced by the two materials, thus reducing the current.

The amount of resistance produced by the two materials depends on the thickness of the copper-nickel coating and the material of the carbon type element used. The RWR89S3R09DRS70 through hole resistor features a 0.10ohm resistance value which provides excellent accuracy and stability. This allows for precise control of current in various applications.
