Introduction to MOV-10D201K

MOV-10D201K is a multi-arrayed, series 10mV-1V, 200mA diverting varistor (MOV) specifically designed to protect vital circuits in electronic gadgets from transients and overvoltage. This MOV series provides protection against both surge and ESD by its reliable overcurrent reaction capability and its ultra-high surge current handling capacity. It offers robust device structure with high temperature, low profile, and high power dissipation with superior protection of electronic circuits in harsh environments.

Application Field of MOV-10D201K

The MOV-10D201K is designed for use in high frequency power switching circuits, telecom systems, consumer electronics, automotive electronics, medical electronics, and other secondary alternating current load applications. It can also be used in high-frequency inverters, home theater systems, and other power devices.

Given its excellent over-voltage protection capabilities, the MOV-10D201K can be used in any application where surge protection is required, such as routers and modems, equipment with networked components, automotive video/audio systems, digital signage, vending machines, and industrial controllers.

Working Principle of MOV-10D201K

An MOV-10D201K is composed of several metal-oxide layers which are put in parallel around a central electrode. Each layer is connected to an input terminal. The MOV-10D201K works when a voltage higher than the rated clamping voltage is applied to the MOV. Once this threshold is exceeded, a large current begins to flow through the MOV, thus diverting the overvoltage away from the protected circuit. At the same time, the current flow through the MOV also creates a voltage back-effect, known as the clamping voltage, which limits the amount of voltage that is allowed to pass through the protected circuit. This clamping voltage is generally much lower than the voltage at which the MOV was triggered.

In addition, the MOV-10D201K also has the capability of self-healing. Its unique properties also allow it to restore its original resistance value after a large surge event, thereby allowing it to be subsequently used again to protect a circuit from the same transient or overvoltage event.

Conclusion

The MOV-10D201K is a durable and reliable Varistor designed for use in high frequency power switching systems and other electronic applications. Its high temperature and power dissipation capacity make it ideal for environments that experience frequent overvoltage issues. It offers excellent overvoltage protection capabilities and has the capability of self-healing, which makes it an ideal choice for surge protection applications.
