Varistor devices are used extensively in electronics and many other industries. They are employed to protect circuits from overvoltage, excessive currents, and other spikes or surges in power. The ROV14-621K-S-2, part of the ROV series of varistors, is designed to provide both overvoltage protection and EMI/RFI filtering. It is particularly effective in high voltage power supplies and battery management systems.

The unique design of the ROV14-621K-S-2 allows it to provide protection under both AC and DC conditions. The device can handle voltages up to 600V, making it suitable for a wide variety of applications in both consumer and industrial applications. Its compact size and low profile make the device suitable for use in tight spaces or in areas difficult to access. The varistor is also designed to have low leakage current and low capacitance, allowing for high immunity performance.

The ROV14-621K-S-2 is constructed with lead and zinc oxide layers that produce a nonlinear voltage-current characteristic. This allows the device to absorb large voltage spikes and dissipate the energy to the surrounding environment in the form of heat. At the same time, the device is able to block high-frequency interference and reduce particle disturbances.

The device also features an offset voltage adjustment capability. This is achieved by using a connecting resistor across the terminals, which increases the rated voltage value. This feature helps in controlling the protection threshold and the clamping voltage, depending on the application requirements. The device can be configured to provide both transient overvoltage and EMI filtering protection.

The ROV14-621K-S-2 is an ideal solution for a wide range of applications in both commercial and industrial markets. It is perfect for use in industries such as automotive, lighting, solar, communications, medical, and industrial applications. By providing both overvoltage protection and EMI/RFI filtering, the device helps to ensure reliable and safe operation of electronic products
