ROV07-751K

ROV07-751K varistors are known for their ability to control voltage shock and surges. These devices are capable of providing reliable protection to electronic circuits and systems from high-voltage damage. This ROV07-751K varistor is designed for use in TVS (transient voltage suppression) applications, such as used in MOVs (metal oxide varistors).

Application fields

The ROV07-751K varistor has a maximum clamping voltage of 575V, a peak pulse current rating of 4.5KA (8/20μS), and an operating temperature range from -40°C to 85°C. This combination of features makes the ROV07-751K an ideal choice for general purpose transient voltage suppression applications. It is a high-performance device that can be used in a variety of portable electronic devices, such as phones, cameras, and computers. Additionally, it can be used in automotive systems, household appliances, and industrial machinery.

The ROV07-751K is also suitable for use in surge protective devices (SPDs) and other sensitive signal line protection applications. It can be used to provide protection against transients, such as those caused by automotive starting, motor switching, AC line switching, and lightning.

The ROV07-751K’s thermal stability design allows it to work reliably under higher load currents and environmental temperatures. This varistor has a high storage temperature range, making it suitable for use in harsh environments and with high power transient events.

Working principle

The ROV07-751K varistor works by controlling the flow of current during high-voltage transients. When an overvoltage condition exists, the metal-oxide layers in the varistor provide a low-resistance path for a surge of current to pass through. This surge of current is limited by the varistor’s maximum clamping voltage. The varistor then dissipates this surge of current, protecting sensitive components from damage.

The ROV07-751K\'s thermal stability design also contributes to its ability to protect circuits from high-voltage transients. This varistor\'s metal-oxide layers are designed to remain stable at temperatures up to 85°C, preventing the device from becoming electrically noisy or breaking down under extreme temperature conditions.

In summary, the ROV07-751K is an excellent choice for transient voltage suppression applications. This varistor is designed to provide reliable protection against high-voltage transients and surges, while also offering a high level of thermal stability. Its wide application field and high performance makes the ROV07-751K an excellent choice for general purpose TVS, MOVs, and SPD applications.
