Working Principle

The working principle of the 40F20R is based on the Ohm’s Law. This law states that the voltage across a resistor is equal to the current times the resistance. In the 40F20R, this law is utilized by the resistive element, which is composed of a metallic conductor, a substrate material, and an insulating layer. The conductor element is made of a metallic material, such as copper, which provides electrical conductivity. The substrate material is usually a rigid material, such as glass-filled plastic or ceramic, which provides mechanical stability to the component. The insulating layer, usually composed of a silicone-based material, protects the conductor element and provides electrical isolation.

When a current is applied to the 40F20R, the conductor element in the resistive element heats up, causing a change in resistance. This change in resistance affects the current flow, allowing the component to sense the electrical parameters. This sensing process allows the 40F20R to be used in a variety of control applications. In particular, the 40F20R are used in safety applications to provide protection from voltage levels that could cause damage to the electrical components.
