MOV-20D391K, also referred to as Metal Oxide Varistor, is a key component in electrical and electronic devices. It is used to protect components from overvoltage and overcurrent. It should be noted, however, that while MOV-20D391K offers good protection, it is not suitable for high power applications.

MOV-20D391K is a type of Varistor, which is a device used to protect against overvoltage and overcurrent. It consists of a large plate metal oxide material surrounded by a copper connection plate, and a second plate made up of a semiconductor material.

When MOV-20D391K device is subjected to an overvoltage or overcurrent, the metal oxide material breaks down and quickly dissipates the electrical energy, reducing the overvoltage or overcurrent. This protects the device from being damaged.

MOV-20D391K has wide applications in the electronics industry. It can be used in power supplies, overvoltage protection circuits, motor drives, electronic circuits, and many other applications.

The working principle of MOV-20D391K is simple. When an overvoltage or overcurrent is applied, the metal oxide material breaks down and dissipates the energy, protecting the device from being damaged.

When the overvoltage or overcurrent falls below a certain threshold, the metal oxide material will recover back to its normal state, allowing the device to continue working.

MOV-20D391K is a convenient and cost-effective solution for overvoltage and overcurrent protection. It is easy to install and provides reliable protection to the components. In addition, it provides a stable voltage level over long periods of time.
