The ROV20H471K-2 is a surface mounted Varistor commonly used in electronic products to protect them from electrical overstress. It is used in many electronic products such as computers, mobile phones, cameras, MP3 players, and more. The purpose of the ROV20H471K-2 is to provide over-voltage protection while still allowing voltage fluctuation within the desired range.

Varistors are a type of voltage-dependent electrical component that protect electronic components from voltage spikes and other types of electrical overvoltage. They work by limiting the current to a predetermined safe level and dissipating the voltage by making a conducting path for the current. When the voltage exceeds a certain threshold, the varistor will short circuit, allowing the current to pass through and dissipating the excess voltage.

The ROV20H471K-2 is a multi-layer varistor (MLV) with a higher maximum clamping voltage than most other varistors. It has a voltage breakdown at 28V AC/DC and the voltage range is 2 to 28V DC. The breakdown voltage of this ROV20H471K-2 is 11.6V when the ambient temperature is 0-40℃. The series resistance is applicable to 6.35V or more and the Max. leakage current is during the range of 0.5mA to 1.5mA.

The ROV20H471K-2 is designed to protect against transient voltage and is suitable for use in many applications such as automotive, computers, communications, and industrial electronics, etc. In all these applications, an ROV20H471K-2 protects against damage caused by excessive voltage and current.

The working principle of the ROV20H471K-2 is based on the “charge transfer effect”. This effect is a particular property of varistors. When a voltage spike occurs, charge accumulates on the device’s surface, creating a high electric field. This electric field causes the varistor to become electrically conductive, allowing the current to flow through the device and dissipate the excess voltage.

The ROV20H471K-2 provides quick response time and lower leakage current, making it ideal for automotive and industrial application. Its design makes it resistant to temperature and humidity, so it is suitable for use in adverse environmental conditions, such as high temperatures and humidity. The ROV20H471K-2 also features high surge capability and high endurance ratings which make it a perfect selection for use in many industrial and automotive applications.

The ROV20H471K-2 is a versatile device which can be used in many applications. It is a great option for protecting electronic components from electrical overvoltage damage or to prevent system malfunctioning due to high voltage transients. This device is also used to reduce EMI/EMC issues, which is essential for any electrical system.
