TVS (Transient Voltage Suppressors) Varistors and MOVs (Metal Oxide Varistors) are two types of electrical protection devices. They are designed to protect electrical circuits and their components from electrical overvoltage conditions, which can cause damage and reduce the performance of electronic equipment. The ROV07-821K is an example of a TVS/MOV device.

The ROV07-821K is an aluminum oxide metal oxide varistor. It has a high current rating of 25A and a low voltage rating of 125V. It is designed to protect sensitive electronic components from overvoltage transients such as electrical spikes caused by lightning, motor starts, power fluctuations, and other sources. It is a low leakage device, meaning it is designed to not pass any current until the voltage rises to a certain level.

The ROV07-821K is suitable for a variety of applications, including power supplies, lighting, switching, and motor control applications. It is particularly useful in applications that require surge protection, including industrial applications. It is also suitable for consumer applications, such as household appliances and personal computers. It can be used as an individual device or part of a larger surge protection system.

The ROV07-821K works by dissipating energy caused by overvoltage. When the voltage reaches a certain threshold, the ROV07-821K device will start to pass current. This current will create a path to the ground, allowing the overvoltage to be dissipated safely. The ROV07-821K is designed to respond quickly and reliably, allowing it to absorb and dissipate energy within a few microseconds. Once the overvoltage is gone, the device will reset itself and be ready for use again.

The ROV07-821K is highly reliable and is designed to have a long life in even the most extreme environmental conditions. It is rated for temperatures from -55 to +125 degrees C and is designed to handle high peak current pulses of up to 25A. It is also resistant to a variety of chemicals and solvents. Additionally, the device has a high surge energy rating, making it capable of withstanding multiple surges without fail.

In summary, the ROV07-821K is a metal oxide varistor suitable for a wide range of applications requiring surge protection. It has a high current rating of 25A, a low voltage rating of 125V, and is capable of handling peak current pulses of up to 25A. It is also durable, withstanding temperatures from -55 to +125 degrees C and being resistant to a variety of chemicals and solvents. Finally, it has a high surge energy rating, making it capable of withstanding multiple surges without fail. This makes it an ideal choice for applications requiring surge protection.
