VAR-18107077M3P-XK

Varistors, MOVs, are widely used in various electronics and electrical applications. The VAR-18107077M3P-XK series variable resistors are an important part of these applications and have been designed to meet the needs of modern electronics. They are made of a special ceramic body that contains two distinct layers, a bottom layer and a top layer. The bottom layer is made up of a dielectric material that provides electrical insulation. The top layer is made up of a conductive material that provides electrical conductivity. When a voltage is applied across the two layers, the electrical conductivity of the material is modified causing a change in the electrical resistance of the device.

VAR-18107077M3P-XK series varistors are widely used in various applications such as overvoltage protection, surge protection, lightning protection, AC switch shocks, DC motor drive stabilization, and high-voltage switchgear. To protect sensitive circuitry, the varistors are designed to have high electrical resistance during normal operation. When Voltage Transient is applied, it then reduces its resistance and dissipates the transient energy. The VAR-18107077M3P-XK series is engineered for both high-voltage and low-voltage applications, and is able to dissipate up to 10 Joules of energy.

The working principle of the VAR-18107077M3P-XK series variable resistors is based on the materials used in their construction. As the voltage is applied across the two layers of material, the dielectric material undergoes a variable resistance effect. This is caused by the variation in the resistance of the materials due to the change in the voltage. When the applied voltage reaches the breakdown voltage of the device, it begins to dissipate the current. The dissipated energy is then directed to the protective circuits in the device, keeping the sensitive circuitry safe from transient voltages.

VAR-18107077M3P-XK series varistors are used in a wide variety of electronic and electrical applications. They are especially useful for overvoltage protection, surge protection, and ESD protection, as these devices offer a reliable and economical solution to protecting against transient voltages. In addition, they are ideal for lightning protection, as they are able to dissipate high Joules of energy. The devices also find use in DC motor drives and other high-voltage switchgear, such as high-voltage switches.

In summary, VAR-18107077M3P-XK series variable resistors are designed to offer reliable and economical protection from transient voltages. They are made of special ceramic material that includes two distinct layers, a dielectric material and conductive material. As the voltage is applied across the device, the resistance of the material changes, allowing the device to absorb and dissipate the current. This keeps sensitive electronics and electrical circuits safe from damage. They are ideal for lightning protection, overvoltage protection, surge protection, AC switch shocks, and DC motor drive stabilization.
