TVS - Varistors, MOVs

TVS stands for Transient Voltage Suppressor. It is a type of device used to protect sensitive electronic components from voltage spikes. It is a device that absorbs the electrical surge, dissipates it or switches it to ground. TVS devices include Varistors, MOVs (Metal Oxide Varistors) and other related devices.

The ROV07H470K-2 is a metal-oxide varistor (MOV) designed for use as a surge-protection component. It is designed to protect against overvoltage transients caused by load switching, lightning strikes, and nearby power line crossings, and is primarily used in AC line protection applications. The device consists of zinc oxide cells encapsulated in a flame resistant UL 94V-0 plastic case. It has a low voltage limit of 10V and a high voltage limit of 475V.

Working Principle of ROV07H470K-2

When a voltage surge occurs, the MOV will absorb the surge energy or switch the surge current to ground. As the voltage rises, the MOV’s internal field strength increases, which causes it to decrease its resistance, allowing a larger current to flow through it. This will absorb the surge energy or switch the surge current to ground. Once the voltage has returned to its normal level, the resistance of the MOV increases again, and it will no longer allow large currents to pass through it.

Applications of ROV07H470K-2

The ROV07H470K-2 can be used in a variety of applications such as AC mains, telecommunications, networking, automotive electronics, consumer electronics, medical equipment, process control, power supplies, and more. It can be used in applications that require protection from high-energy overvoltage transients such as load switching, lightning strikes, and power line crossings. It also offers fast response times and excellent repetitive surge protection in a wide variety of conditions.

The ROV07H470K-2 is designed for use in circuits that are connected directly to the AC power line. It can be used in applications where direct connection to the AC power line is required, such as air conditioners, refrigerators, water heaters, fans, and so on. It is also suitable for applications where there are voltages between 11V and 475V AC. It is suitable in a variety of different environments, including both commercial and industrial settings.
