Varistors, sometimes referred to as voltage-dependent resistors (VDRs), are components that are designed to protect against sudden increases in voltage. They act as a “clamp” in that they prevent voltage levels from exceeding the expected range. The application of varistors, also known as Metal-Oxide Varistors (MOVs), is becoming increasingly popular in the rapidly growing market of electronic devices. The VC2220K102R035 is one such MOV with its own unique characteristics and functions and is particularly suitable for use in power conversion systems.

The VC2220K102R035 is specifically designed to be used as surge absorbers in AC power supplies, power converters, and UPS. It is made up of two high-performance, low-leakage movs connected in series. Between the movs is a ceramic plate with a layer of varistor material and between the varistor and the plate is a fusible resistor. The VDRs are designed to be integrated into the circuit and can withstand voltages up to 250 VAC, which is well beyond the normal AC range. The VC2220K102R035 has a working temperature range from -40°C to +85°C, an insulation voltage of 10KV, and a dielectric strength of 1500VAC.

The VC2220K102R035 is designed to protect electronic circuits from overvoltages caused by lightning, power supply failure, switching surges, and other sources. The MOV has two terminals, F1 and F2, which are connected together to create a single circuit. When an overvoltage occurs, the MOV acts as a short circuit and redirects the excess voltage and current away from the protected circuit. Once the voltage returns to normal levels, the VDR automatically reopens the circuit and the device resumes normal functioning.

The VC2220K102R035 is also designed to respond quickly to voltage changes. This is achieved by the varistor material, which is a special electro-ceramic material that changes its resistivity when exposed to a voltage change. This change in resistivity causes the voltage across the MOV to change, which in turn causes the current across the MOV to increase or decrease depending on the direction of the voltage. This helps to minimize the damage to the protected circuit, as the MOV acts as a sort of \'dynamic resistor\'.

The VC2220K102R035 is an essential piece of protective equipment for many power conversion and power protection systems, as it is designed to respond quickly and effectively to voltage changes, protecting the connected components from damage. Its use is growing rapidly as more devices become increasingly interconnected and exposed to an ever-growing range of potentially damaging factors.
