TVS – Varistors, MOVs

Varistors and MOVs (Metal Oxide Varistors) are two types of voltage dependent resistors or VDRs. To understand the MOV-10D471K and its application field and working principle it is important to have an understanding of both VDRs. A Varistor is a voltage dependent resistor device used to protect electronic circuits from high levels of voltage or applied transients such as lighting strikes or electrical surges. A Varistor works by exhibiting a sudden increase in electrical resistance when subjected to an increasing voltage. This change in electrical resistance is what protects circuits and components from the damaging effects of sudden, sharp increases in voltage. Generally the higher the peak voltage rating of the Varistor, the greater its level of protection. MOVs are voltage dependent resistors similar to Varistors, however they are specifically designed to provide protection against electrical transients. MOVs are commonly used in electrical circuits to provide protection from voltage surges. They are a safer alternative to standard fuses as, unlike fuses, they operate automatically and do not require resetting or replacing.The MOV-10D471K is a type of MOV designed specifically to provide circuit protection from voltage transients. The MOV-10D471K is designed to be used in electrical circuits with operating voltages of up to 10V. The MOV-10D471K is designed to be used to protect circuits from voltage transients with speeds of up to 250V/μs. Additionally, the MOV-10D471K has a peak voltage rating of 10,000V and a breakdown voltage of 4,150V.The MOV-10D471K’s main application is in the protection of devices which are susceptible to damage from voltage transients. It can be used in a wide range of applications including consumer electronics, automotive electronics, and industrial applications. The MOV-10D471K is also suited to computer networks, telecommunications systems, and high voltage electronic systems. The MOV-10D471K utilizes a voltage dependent mechanism based on the metal oxide material. The voltage dependent mechanism works by exhibiting a sudden increase in resistance as the applied voltage increases. In the case of the MOV-10D471K, the sudden increase in resistance occurs when the voltage reaches the 4,150V breakdown voltage. At this point, the MOV-10D471K’s resistance dramatically increases, effectively preventing any further current flow through the circuit. This sudden increase in resistance is what protects the circuit, and its components, from voltage transients and other surges.In conclusion, the MOV-10D471K is a metal oxide varistor specifically designed for the protection of circuits from voltage transients. Its main application is in the protection of vulnerable devices which are susceptible to voltage surges. The MOV-10D471K works by exhibiting a sudden increase in resistance when the applied voltage reaches the 4,150V breakdown voltage, effectively preventing any further current flow through the circuit.
