TVS - Varistors, MOVs (Transient Voltage Suppressors, Metal Oxide Varistors), are recognized as one of the most reliable surge protection solutions against over-voltage. ROV14H102K-2 is one of the most popular TVS - Varistors, MOVs in the electronics market.

The ROV14H102K-2 is mainly composed of two parts, a metal oxide varistor (MOV) and a filter capacitor. The MOV is a silicon free device with a ceramic outer body that helps protect against over-voltage by quickly dissipating the energy of the transient voltage waveform. It consists of a metal plate and two electrodes. These two electrodes create a strong bridge at one side of a plate, and a weak bridge at the other side. Using this configuration, when exposed to high voltages, the transient is conducted towards the weak bridge, allowing the voltage to disperse quickly.

The filter capacitor is connected in parallel to the MOV, and its purpose is to reduce or absorb the high voltages generated by the surge and help reduce the peak current. This additional protection helps protect against high voltage spikes and ensures that the end device is not damaged.

The ROV14H102K-2 is mainly used in power supplies, AC/DC converters, and power management systems. It is designed to protect against voltage transients up to 16 KV and can handle maximum currents up to 8 A. It also has a very low capacitance and very low leakage current.

The working principle behind ROV14H102K-2 is quite simple. When the voltage surge passes through the MOV, the weak bridge will be activated and the high voltage will quickly be dissipated. This causes the voltage across the MOV to drop to a safe level, protecting the end device from damage. The filter capacitor will then absorb the remaining current, reducing the peak current. This protects the internal components of the system as well as the MOV itself.

The ROV14H102K-2 is a reliable and effective surge protection solution that can help protect against a wide range of voltage transients. It is designed to handle a wide range of currents and voltages, making it an ideal choice for power supplies, AC/DC converters, and power management systems. Its low capacitance and low leakage current makes it a perfect choice for applications that require high levels of protection.
