Overvoltage protection is essential in many types of high-power circuits and systems. The ROV07-121K-2 is a particularly reliable overvoltage protection component, providing professional and comprehensive protection against overvoltage. It is widely used in telecommunication systems, electronic products, equipment automation systems, particularly in power supply systems, computer interface systems, and automotive circuits.

The ROV07-121K-2 is a voltage-dependent resistor, also known as a Varistor. Varistors are designed to allow current to flow in one direction up until a certain voltage is applied. At this voltage, known as the breakover or clamping voltage, the Varistor will introduce a large surge of current into the circuit and effectively “short out” any overvoltage that may be present.

The ROV07-121K-2 utilizes two different technologies for optimal overvoltage protection. The first is a ZnO Stack Varistor, which allows the metal oxide stack inside the ROV07-121K-2 to absorb large amounts of energy when activated. The second is a MOV (metal oxide varistor) which clamps the voltage. The MOV is designed to bring down the voltage to below the rated clamping voltage.

This dual protection system combined with the use of a metal oxide film gives the ROV07-121K-2 excellent lightning protection capability, making it an ideal choice for circuits and systems that are exposed to high levels of transient voltage. In addition, the ROV07-121K-2 also features an improved Clamping Ripple Current that helps to reduce the transient voltage spike generated by the device when activated.

In conclusion, the ROV07-121K-2 is a reliable and efficient overvoltage protection device. Its advanced protection technologies and improved clamp ripple current provide robust protection and ensure smooth operation of circuits and systems exposed to overvoltage.
