A varistor or variable resistor is an electronic component that has a resistance that is dependent on the applied voltage. This resistance is usually nonlinear, which means that it varies with the amount of voltage applied. Varistors are used in many applications, such as electrical protection, filtering, electrostatic discharge protection, and signal conditioning. The ROV14H470K-S-2 is an example of a varistor.-

The ROV14H470K-S-2 Varistor is an axial leaded disc type varistor with an operating voltage of 14V. It has a high pulse strength of 180A, a rated power of 4.5 Watts, and an insulation resistance of 1000MΩ. The device is made up of metal oxide varistors with a lead-free tin/silver/copper fusing coating. The varistor has a radial lead with a split back design.

The ROV14H470K-S-2 Varistor has a high surge current and a low clamping voltage. It is designed to provide a secure connection between an I/O port and the PCB. It is designed to protect against EMI/RFI and ESD interference. It is also designed to reduce noise and other high-frequency signals.

The working principle of the ROV14H470K-S-2 Varistor is based on the current imbalance between the two terminals. When a voltage is applied to the two terminals, the current through the varistor is increased. This increase in current causes an imbalance between the voltage applied and the voltage across the device. As the current increases, the voltage across the device decreases. When the current reaches the rated breakdown voltage, the device begins to conduct current, providing a low impedance path from one terminal to the other.

The ROV14H470K-S-2 Varistor has a wide range of applications, such as ESD protection of I/O ports, surge suppression, voltage clamping, and noise attenuation. It is used in LCD TVs, computer monitors, set-top boxes, and other consumer electronics. It can also be used in automotive, industrial, and HVAC applications. The varistor can be used to protect against EMI, RFI, and ESD interference, as well as reduce noise and other high-frequency signals.

The ROV14H470K-S-2 Varistor is a reliable and cost-effective solution for protecting against EMI, RFI, and ESD interference. It is easy to install and requires minimal maintenance. The varistor offers a high surge capacity and low clamping voltage, making it an ideal choice for applications where protection from high-frequency interference is desired. Additionally, it can be used for EMI/RFI suppression, surge suppression, and voltage clamping.
