Varistors, or voltage dependent resistors (VDRs), are often used as a surge protection device (SPD) in AC power supplies. The V120MLA1210H is a specialized type of VDR designed to provide superior protection against electromagnetic disturbances, spikes and surges.

The V120MLA1210H uses metal-oxide film to provide a low-impedance path for voltage spikes and surges. This film is composed of Zinc Oxide particles, which have the property of becoming resistive as the voltage across them increases. The varistor responds to higher voltages by increasing its resistance, thus limiting the amount of current that can flow through it, and preventing it from being damaged by a sudden surge or spike of voltage or current.

The V120MLA1210H is suitable for use as a transient voltage suppressor (TVS) in a wide variety of applications, such as telecom and networking systems, computer systems, power supplies, industrial, consumer and automotive electronics, and other systems requiring protection against EMI/RFI. It is also ideal for use in over-voltage protection circuits, for suppressing voltage spikes in solar power, photovoltaic and off-grid systems.

The V120MLA1210H is designed to be easy to install and maintain. It features solderable terminals and is rated for operation at temperatures ranging from -25 to +125 degrees Celsius, as well as 25g shock and 6g vibration. It also offers low ESR and high capacitance for improved noise suppression.

The working principle of the V120MLA1210H is fairly simple. When a voltage that exceeds the breakdown voltage of the device is applied, the current is diverted through the metal oxide layer and the device begins to act like a resistor, limiting the current that can flow through it. This prevents further damage to the device from excessive voltage and current. The response of the device is determined by the size of the metal oxide layer, and the Zinc Oxide particles used in the production of the V120MLA1210H have the property of becoming resistive under increased voltage.

In conclusion, the V120MLA1210H is a versatile, reliable and effective surge protection device that can be used to protect sensitive electronics from overvoltage, surges and spikes. It is easy to install, offers low ESR and high capacitance for improved noise suppression and is designed to withstand temperatures ranging from -25 to +125°C. It is suitable for a wide range of applications, and can be used to protect telecom and networking, PC, power supplies, industrial, consumer and automotive electronics, as well as utility systems.
