ROV14-431K-2

Transient voltage suppressors, like the ROV14-431K-2, are widely used in electrical and electronic devices, to protect against transient voltage and current events. They are a form of voltage-limiting device, which prevent damage to the components in a circuit, due to overvoltage. The ROV14-431K-2 is an example of a varistor, also known as a voltage-dependent resistor (VDR).

Varistors are divided into two types, Unidirectional and Bidirectional. Unidirectional varistors allow current to pass in one direction only, while Bidirectional varistors allow current to pass in both directions. The ROV14-431K-2 is a Bidirectional varistor.

The ROV14-431K-2 has an operating voltage of 14V, with a peak surge current of 431kA. It is designed to protect against electrical/electronic components from overvoltage caused by electrical transients. It can be used in a variety of applications, including power supplies, motors, power meters, and instrumentation.

The working principle of a varistor is relatively simple. The device is composed of a metal oxide material, such as zinc oxide, ceramic, or polymer, which has been manufactured into a disc-like shape. The material acts as a resistance element, and the resistance of the device is determined by the applied voltage. As the voltage increases, the resistance decreases, and the device will provide a low impedance path for the transient energy.

When a transient voltage occurs, the ROV14-431K-2 will immediately conduct the energy away, providing protection for the components in the circuit. The device reaches its breakdown voltage, and theavalanche voltage clamping action of the device will absorb the energy from the transient. The device is designed to absorb and dissipate most of the transient energy, without damaging the circuit components.

The ROV14-431K-2 can be used in a variety of applications, or integrated into any electrical or electronic device, due to its small size and low cost. It is a great option for protecting electrical and electronic components against electrical transients, and is specifically designed to provide protection against electrical surges with peak current ratings up to 431kA.
