TVS - Varistors and MOVs are among the most common forms of transient voltage suppressors (TVS) on the market. Varistors are specifically designed to protect equipment from transient voltages, while MOVs provide both over-voltage and over-current protection. ROV07-471K-2 is an MOV varistor from TDK Corporation that is suitable for a variety of application fields.

ROV07-471K-2 is designed to protect automotive and consumer electronics and sensitive telecom equipment from over-voltages and over-currents. It is able to suppress voltage up to 441V peak with a maximum of 32J energy per pulse and can be used in frequencies ranging from 0Hz to 400kHz. The device is terminated with two solderable contacts and is constructed in a molded plastic package that is UL94V-0 rated.

The working principle of ROV07-471K-2 is simple and effective. It utilizes its varistor characteristics to dissipate most, if not all, of the transient energy. The device contains two metal-oxide varistors (MOV) made with sintered zinc-oxide powder. When voltage is applied, the varistors conduct, providing a low resistance path and diverting the flow of electricity. The MOV then dissipates the energy by allowing a large current to flow at a much lower voltage, converting the energy to heat. The heat is then dissipated through the device\'s epoxy body.

Additionally, ROV07-471K-2 is very easy to install and offers superior performance compared to traditional MOV devices. It is designed with an improved thermal derating trend that provides greater reliability and insulation protection, in addition to having a highly repeatable offline breakdown characteristic. For design engineers, this device provides a reliable and economical solution that is ready to use and compliant with a variety of standards.

In conclusion, ROV07-471K-2 from TDK Corporation is an effective MOV varistor that offers reliable protection from transient voltages and over-voltage/over-current protection. Its improved thermal derating trend allows for superior performance compared to traditional MOV devices. The device is cost-effective, easy to install and compliant with a variety of standards. With this product, design engineers can be sure to protect their sensitive equipment from dangerous over-voltage and over-current conditions.
