Working principle of VE1812K301R115

The VE1812K301R115 utilizes a unique combination of materials that provides excellent protection from electrical overstresses. In the schematic shown below, the voltage is applied to the MOV’s (Metal Oxide Varistor’s) two terminals. When the voltage is below the MOV’s rated clamping voltage, it will not conduct current. Once the voltage reaches the MOV’s rated clamping voltage, current begins to flow through the device.

The VE1812K301R115 contains a ceramic body with a sintered metal-oxide layer inside. When the voltage applied across the MOV exceeds the specified breakdown voltage, the ceramic layer begins to conduct and the current is limited. The current is limited to a safe level that will avoid damage to the protected circuit.

The VE1812K301R115 is designed to protect standard AC power lines and signal lines. It will clamp surges and overvoltages and reduce common-mode noise, while its radial leads provide easy mounting options that enable it to be used in a wide variety of applications.

Conclusion

The VE1812K301R115 is a metal oxide varistor (MOV) that is specifically designed for transient voltage suppression applications. It is used in several fields, including industrial control, telecommunications, power systems, household applications, and entertainment. The VE1812K301R115 utilizes a combination of materials in its structure to protect circuits from electrical overstresses. When the voltage exceeds the specified breakdown voltage, current begins to flow through the device and is limited to a safe level that will not damage the protected circuit.
