ROV14-390K-S-2

ROV14-390K-S-2 is a type of metal oxide varistor (MOV) that serves as surge protector against various overvoltage transients and power disturbances. It also acts as an electrical noise absorber for high-frequency data and signal paths. As an MOV, ROV14-390K-S-2 is equipped with a movable metal oxide element, which is used to absorb and dissipate surge energy when an overvoltage spike occurs. This element is connected to both ends of the MOV, forming a moveable junction that is not adjustable by an external circuit. The primary application of the ROV14-390K-S-2 is as an overvoltage transients suppressor in electronic systems and power circuits, providing a reliable level of overvoltage protection for components, sub-systems, and systems.

The ROV14-390K-S-2 uses Ceramic Varistors (CVO) as its electrical noise absorption element. The CVO has a capacitive element (C) and a resistor element (R-O) arranged in series. The capacitive element absorbs small electrical noise signals while the resistor element dissipates larger transient surge energy. When coupled with an ESD protection diode, the ROV14-390K-S-2 provides both ESD and EMI protection. The enable-disable function of the ROV14-390K-S-2 allows for a reset of the circuit in case of overvoltage.

In addition to its application as an overvoltage transient protector, the ROV14-390K-S-2 can be used in a wide range of electronic applications. It is suitable for circuit protection in various types of communication and control systems, as well as in power supply designs. It can also be used in general electronic system noise mitigation and protection against overvoltage transients. Its enable/disable feature makes it an ideal choice for systems that require protection against accidental power outages.

The working principle of the ROV14-390K-S-2 is fairly simple. When an overvoltage transient occurs, the movable metal oxide element inside the device creates a voltage division in the circuit. This voltage division causes some of the transient energy to be dissipated by the element. The dissipated energy is absorbed by the resistor element (R-O)in the CVO and released as smaller voltage transients. These smaller voltage transients allow the device to protect against higher levels of ESD than what would otherwise be possible without the ROV14-390K-S-2.

The popularity of the ROV14-390K-S-2 comes from its ability to provide reliable overvoltage protection to a wide range of applications. Its enable/disable function allows for a reset of the circuit in case of overvoltage, while its CVO absorption coating maintains emission levels even in the presence of high-frequency transients. In addition, the ROV14-390K-S-2 provides ESD protection in combination with an ESD protection diode, making it an ideal choice for a wide range of applications.

Overall, the ROV14-390K-S-2 provides a reliable level of protection against overvoltage transients, creating a safe and secure operating environment for electronic systems and power circuits. Its enable/disable feature makes it a great choice for resetting a circuit in case of voltage disruption as well. The combination of the metal oxide element and CVO absorption coating makes the ROV14-390K-S-2 an ideal choice for applications requiring both ESD and EMI protection. The ROV14-390K-S-2 is a great solution for providing reliable protection against overvoltage transients and power disturbances.
