TVS - Varistors, MOVs are active components used to protect circuits from high-voltage transients. The ROV10H511K is a surface mount varistor that provides reliable overvoltage protection against lightning surges and transient spikes generated by industrial machinery, motors and other power supplies. This device offers very low capacitance and is well suited for high-speed signal line protection applications.

The ROV10H511K is a voltage dependent resistor (VDR) which provides high-voltage protection on both AC and DC systems. It consists of two metal-oxide layers separated by a thin layer of Pb-free solder alloy. The device is designed to clamp the voltage when a preset over-voltage threshold is reached. The device is triggered when the applied voltage reaches the peak response voltage, which is generally around 10 percent higher than the rated voltage.

The ROV10H511K is ideal for applications that require a low capacitance voltage protection device. The low ESR value of this device allows it to be used in high frequency applications, up to 500 KHz. It can be used in combination with a parallel capacitor for high signal line attenuation.

The device also has a high surge handling capability and can safely handle up to 8000V peaks of voltage. This makes it ideal for a broad range of applications including consumer electronics, computer systems, telecommunications, industrial machinery, motor controllers and air conditioners.

When looking for a voltage protection device, the ROV10H511K is a great option for embedded systems that require high reliability and low capacitance. The low ESR value of this device allows it to be installed in small space, providing a reliable solution in a wide range of applications.

The working principle of the ROV10H511K is quite simple. When the voltage applied to the circuit exceeds a certain level, the device absorbs the excess current and blocks the voltage, preventing any damage to the circuit. This process continues until the applied voltage decreases below the threshold value. The device also provides thermal protection and is designed to withstand up to +85°C temperatures.

The ROV10H511K is widely used in a variety of applications due to its low capacitance, high surge handling capability, and reliable over-voltage protection. This device offers a reliable solution in consumer electronics, industrial machinery, motor controllers, and air conditioners. It is also highly recommended for use in high-speed signal line protection applications due to its low ESR value.
