Varistor 4 Electrical4u Varistors are used as control or compensation elements in circuits either to provide optimal operating conditions or to protect against excessive transient voltages. when used as protection devices, they shunt the current created by the excessive voltage away from sensitive components when triggered. Varistors are semiconductor devices designed primarily to protect electronic circuits from voltage spikes and transients. the most widely used type is the metal oxide varistor (mov), typically composed of zinc oxide (zno) grains separated by grain boundaries that create semiconductor junctions (nahm, 2020).
Varistor Wholesalers Varistor High Quality Unlike the fuse or circuit breaker which offers over current protection, the varistor provides over voltage protection by means of voltage clamping in a similar way to the zener diode. What is a varistor? a varistor is a varying resistor whose resistance depends on the applied voltage. the name has been coined by linguistic blend of words; “varying” and “resistor”. they are also known by the name vdr [voltage dependent resistor] and have non ohmic characteristics. therefore, they come under non linear type of resistors. A varistor is an electronic component designed to protect electrical circuits from excessive voltage surges or transients. it is a nonlinear resistor whose electrical resistance varies significantly with changes in voltage. Varistors are critical components of a pcb. the name “varistor” comes from combining two names: voltage and resistor. voltage resistor = varistor. a varistor is mainly a safety tool for a pcb. it doesn’t contribute to the pcb’s function as other components do; instead, it protects it.

Definition: a varistor is a 2 terminal semiconductor device that protects the electrical and electronic devices from overvoltage transients. its resistance is dependent on the applied input voltage. the word varistor is formed by the combining vari able and resi stor. There are many kinds of varistors on the market suitable for various applications, making choosing the right one to protect a given circuit challenging. what are varistors? a varistor is a blend of the words “varying resistor” because its resistance varies as the voltage applied to it changes.
