Non-linear Resistors

Non-linear resistors, also known as varistors or voltage-dependent resistors, are electronic components that exhibit a nonlinear resistance characteristic with respect to the applied voltage. They are primarily used for voltage clamping, surge protection, and transient suppression in electronic circuits.

The resistance of a varistor decreases with an increase in voltage, allowing it to provide a low resistance path for transient currents that exceed a specified threshold. When the voltage level drops below the threshold, the resistance increases, returning the varistor to its high impedance state. This property makes them useful for protecting sensitive electronic components from voltage surges and spikes.

Varistors are available in two types: metal oxide varistors (MOVs) and silicon carbide varistors (SiCVs). MOVs are the most common type, and they can handle a wider range of voltages than SiCVs. SiCVs, on the other hand, can handle higher temperatures and are more suitable for high power applications.

Non-linear resistors are widely used in power supplies, surge protectors, electronic ballasts, motor control circuits, and telecommunication systems. They are available in various package types, including through-hole, surface mount, and radial leaded packages.
