TVS - Varistors, MOVs (Transient Voltage Suppressors, Metal Oxide Varistors) are important protector components used to suppress voltage spikes. ROV05H330K-2 is one such component, usually employed in the fields of electronic engineering and electrical engineering.

ROV05H330K-2 is a MOV with an ESD capability of 15,000 – 20,000 volts, based on its Varistor Voltage (V0-1mA). It is a 333V AC (Working Voltage) 350V (VTM) device. It offers online mechanical and electrical protection and also protects against transients, ESD and EFT. It is rated up to 25kHz, making it a good choice for today’s high-speed digital circuitry.

ROV05H330K-2 is mainly used to protect computer systems, serial communication ports and other digital systems. It is also employed in sensitive electronic components that need to be protected from overvoltage. It is suitable for use with PoE (Power Over Ethernet) applications, digital TV, FTTX (Fiber to the Home) & FTTH (Fiber to the Home). It also provides additional protection in comparison to MOVs, due to its ESD capability.

The working principle of ROV05H330K-2 is quite simple. It absorbs or blocks the excessive electric current coming through the circuit, thereby protecting the equipment or system. Its inherent nonlinear resistance develops a "clamp voltage" which, when exceeded, will form a protective barrier. This limits the voltage entering the equipment to an acceptable level, thus avoiding damage. It also provides additional protection by dissipating the excess energy generated by the ESD (Electro-Static Discharge) event. It is therefore better suited to protect your equipment from ESDs and transient voltages.

In Summary, the ROV05H330K-2 is an effective device for providing electrical and mechanical protection, while also protecting against transient events, ESD and EFT. It is particularly suitable for protecting computer systems, communication ports and other digital systems, as well as sensitive electronic components from overvoltage. Its simple working principle makes it an excellent choice for efficient suppression of transients, and its ESD capability offers additional protection from ESD events.
