Working Principle

The basic working principle of a through hole Resistor is simple and straightforward. It works by utilizing electrical resistance to reduce the current that flows through it. Resistance is measured in ohms, and is directly proportional to the voltage applied across a component\'s terminals. As the insulation component is exposed to incoming electrical current, the electric resistance between terminals increases as the voltage level increases.

A through hole resistor is composed of an insulating material which typically consists of metal oxide (notably ceramic, mica, porcelain or other metallic composition). Metal oxide materials are typically used because of their high electrical conductivity and relative temperature stability. The type and mixture of metal oxides used to construct the insulation component will have a direct effect on the overall electrical characteristics of the resistor.

The RWR78S3R40FRB12 Through Hole Resistor is designed to provide stable performance in areas such as high temperature / humidity conditions, as well as efficient power transfer. The additional metal oxide insulators help to create reliable connections between the contact points, providing reliable heat dissipation, and insulation against voltage breakdown.
