TVS - Varistors, MOVs are passive elements consisting of a semiconductor layer with two electrodes, which regulate current and voltage in a wide variety of electronic applications.

MOV-10D781KTR is a specific type of TVS - Varistors, MOVs. It is a surface mounted bidirectional LCD Surge protector that provides over-voltage, over-current and transient protection for various types of LCD displays. This device includes both ESD and surge protection and is designed to protect LCD displays against IEC61000-4-2 surge pulses.

MOV-10D781KTR is widely used in AC/DC adaptors, LCD TVs, monitors, electric saws, energy saving lights and other electronic devices. It also finds application in industrial equipments such as power supply, lighting equipment, motors, electric equipments, and digital equipments.

The application and working principle of MOV-10D781KTR is based on Metal-Oxide Varistor (MOV) technology.

MOVs are semiconductor devices that can limit current and protect circuits from over-voltage and high-voltage surges. They provide excellent steady and transient over-voltage protection, and their function will not change at rated load levels or with frequency changes in the circuit.

When no voltage is applied to the MOV-10D781KTR, the surface of the MOV does not have a large potential voltage difference, so the current between the two electrodes is very small. As the voltage increases, it increases the conduction of current between the two electrodes, and the resistance value decreases, thereby reducing the voltage applied to the MOV. Therefore, the MOV-10D781KTR can protect the circuit from over-voltage.

MOV-10D781KTR is designed to protect an LCD display from over-voltage surges, ESD transients, and EFT transients, and its protection level is IEC61000-4-2, level 4, +4kV contact / +8kV air.

MOV-10D781KTR is a Surface Mount Device (SMD) component and can be easily mounted onto a Printed Circuit Board (PCB) for LCD panel mounting. It is compatible with lead free soldering and AOI (Automated Optical Inspection) processes.

In summary, MOV-10D781KTR is a type of TVS-Varistors, MOVs, which is widely used in electronic applications such as ACDC adaptors, LCD TVs, monitors, energy saving lights and other electronic devices; its application and working principle is based on the Metal-Oxide Varistor (MOV) technology, and it is highly effective in protecting LCD displays from over-voltage and high-voltage surges.
