ROV05H390K-S-2 Application Field & Working Principle

Thermal-protected Varistor (TVS) is a special form of a variable resistor with a large range of resistances. It has a wide variety of uses, ranging from protecting electronics from voltage spikes and surges, to suppressing interference. The ROV05H390K-S-2 is a TVS (Thermal-protected Varistor) designed for electronic protection and surge protection. It is widely used in the electronic industry for its excellent performance.

ROV05H390K-S-2 is a Varistor (Metal Oxide Varistor) that is designed to protect electronic circuits from voltage spikes, surges, and electrical transients. This Varistor is a voltage-dependent, nonlinear resistor that changes its resistance at different voltages. Its resistance decreases at higher voltages and increases at lower voltages, thus providing protection against high surge currents passing through the circuit. It is also able to limit the overvoltage transient voltage that it is exposed to.

The ROV05H390K-S-2 Varistor provides increased circuit protection for devices operating between -55°C and +125°C. This Varistor is designed to be used in applications such as power supplies, motors, and automotive circuits where protection from temporary voltage surges is necessary. It provides a low clamp voltage which makes it suitable for loads which are sensitive to high overvoltage. It has a nonlinear resistance-voltage characteristic (NTC) and a high surge current rating of 10 kA (10/1000 μs).

The ROV05H390K-S-2 Varistor is useful in automotive protection applications, as it is able to limit voltage transients that arise due to sudden changes in electrical loads. It is also able to regulate voltage levels that arise due to load shedding and motor protection. It is able to suppress voltages in the range of -20V to +20V, thus providing additional protection against electrical transients. The Varistor is designed to provide protection against overvoltage and overcurrent.

The ROV05H390K-S-2 Varistor is an easy-to-use device that requires no external components. It is available in various sizes and configurations to accommodate different applications. The Varistor can be soldered onto the leads of the device being protected. It is also possible to mount the Varistor directly onto the device, thus providing the most efficient protection.

The working principle of the ROV05H390K-S-2 Varistor is simple. It is a voltage-dependent, nonlinear resistor that changes its resistance at different voltages. The Varistor has an intrinsic temperature compensation feature which ensures that the Varistor\'s resistance values are precisely calibrated over a wide temperature range. When it is exposed to an overvoltage, the Varistor\'s resistance increases, creating a voltage-clamping effect that limits the overvoltage. This in turn protects the device from high surge currents passing through the circuit.

The ROV05H390K-S-2 Varistor is a useful device that provides superior protection against overvoltage and overcurrent in a wide variety of applications. It has a simple design and does not require any external components. It is available in a wide range of sizes and configurations to accommodate different application requirements.
