TVS - Varistors, MOVs are commonly used components in electronic equipment. Their primary purpose is to limit transient voltages that can be generated by external sources. The ROV14-121K-S-2 varistor is a common type of varistor used in modern electronics. This component combines a high voltage, low leakage and fast response time into a small package that helps protect the circuit from overvoltage transients.

The ROV14-121K-S-2 is a near-ideal varistor with a working voltage rated between 10 and 150volts and an operating current of 1mA to 10A. The device has a low voltage leakage current, of less than 1u A, to ensure a high level of protection. Its fast response time, which is below 1 us, ensures that the device can react to a transient in a matter of microseconds, making sure that the circuit is not damaged.

The ROV14-121K-S-2 is mainly used for transient voltage protection applications in AC-DC and DC-DC power supplies, computer Motherboard, printers, and other digital electronics. The device can also be used for ESD protection, surge protection, overvoltage protection, and other applications. The device is designed to limit the current in a circuit during a transient event, protecting other components from damage due to excessive current.

The working principle of the ROV14-121K-S-2 is relatively simple. The device’s body serves as a connection between two zinc-oxide plates. When an over-voltage enters the device, the zinc-oxide plates expand due to the increased voltage, and the resistance of the plates decreases. This decrease in resistance causes a surge of current to flow through the plates, which dissipates the excess energy and protects the device from damage.

The ROV14-121K-S-2 is an efficient and reliable way to provide surge protection in circuits. The device’s fast response time and low leakage current make it an ideal choice for transient protection applications. The device is also inexpensive, making it a popular choice for cost-conscious electronic designers.
