VE07P00211K Circuit Protection

VE07P00211K is a kind of metal oxide varistors (MOVs) used in circuit protection applications. Varistors are a type of voltage protective device (VPD) which stops surges such as those caused by lightning strikes or other power issues. MOVs are widely used in telecommunications, cable television, automotive, military and medical equipment.

In general, a varistor works by reducing the energy of the spike, preventing it from reaching the electronics connected to it. A VE07P00211K varistor is a non-linear variable resistor that limits overvoltage transients. They are typically designed to work within a specified voltage range, and have different electrical characteristics depending on the voltage range. Specifically, the VE07P00211K varistor has Clamping voltage 18V – 48V, and peak current of 370A.

The working principle of the VE07P00211K varistor is based on the phenomena of non-linearity when enough voltage is applied to a varistor. When the applied voltage across the varistor reaches the varistor’s clamping voltage, it suddenly changes its resistance from a very high state to a lower one. As a result, a large amount of current is then allowed to pass through the varistor. This current then reduces the voltage beyond the varistor\'s clamping voltage and thus prevents damaging surges of current through the system.

The VE07P00211K varistor is commonly used in systems where there is a danger of high voltage transients, such as in lightning protection systems. These varistors can also be used in communication or automotive electronics, or any circuit that needs to be protected from momentary high voltage spikes. VE07P00211K varistors are versatile, reliable and easy to install. They offer a degree of safety to electronic systems that few other components can match.
