ROV20H911K-S

The ROV20H911K-S is a two-terminal varistor designed to provide an overvoltage protection. When the clamped voltage on the ROV20H911K-S is below its breakdown voltage (VBO) a potential is stored on the varistor. In case of overvoltage, the voltage on the varistor will exceed the breakdown voltage and an immediate and non-destructive limitation of the voltage level will occur, while a current will surge through the varistor to ground. The device is designed to deliver reliable and cost-effective protection against overvoltage transients in a wide variety of applications.

The ROV20H911K-S is an ideal candidate for overvoltage protection in power supplies and control systems, as well as in systems where protection from power line transients is needed. It provides superior performance and protection against overvoltage transients up to a maximum breakdown voltage of 9V. Additionally, the device is designed with the highest rated voltage, allowing for greater flexibility in selecting the proper protection device.

The two-terminal varistor of ROV20H911K-S works by quickly shunting away surplus voltage, and providing an inevitable voltage loss which results in the protection of the connected equipment. The device includes a protective diode that helps reduce the effects of inductiveloads. It has a peak current capability of 40A and an energy dissipation of 4J. The device is designed for a wide temperature range of -40°C to +85°C and a maximum operating frequency of 500kHz.

In conclusion, the ROV20H911K-S provides reliable and cost-effective protection from overvoltage transients in a wide range of applications. It is designed with a wide operating temperature range and its peak current capability is 40A along with an energy dissipation of 4J. The device works by quickly shunting away surplus voltage and providing an inevitable voltage loss which results in protection of the connected equipment. The ROV20H911K-S is designed with the highest rated voltage which allows for greater flexibility in selecting the proper protection device.
