VDRS10P420BSE

A varistor, also known as a Voltage Dependent Resistor (VDR), is used in a wide variety of applications. The most common use is for protection from electrical surges and overvoltage, and many industrial, automotive, aerospace, medical and military applications utilize VDRs for this purpose. The VDRs have become increasingly popular as a means of interference protection and line conditioning.

The VDRs offer protection from destructive voltages without relying on fuses or other downtime-causing solutions. The VDRs are designed to respond rapidly to transient overvoltages, limiting the effects of the surge and grounding out the excessive current.

The VDRs are classified according to their working voltage, peak rated power and other parameters. One of the more common VDRs is the VDRS10P420BSE, a high voltage VDR that is commonly used in telecommunications, automotive, power electronics, and other applications.

The VDRS10P420BSE is a bidirectional, multipurpose 400-volt Bidirectional VDR that provides surge protection for a wide variety of equipment. It is designed to provide fast response time to transient overvoltages, protecting sensitive equipment from damage caused by surges and spikes in a circuit. It also limits damaging inrush currents that can be damaging to sensitive components and circuitry.

The VDRS10P420BSE is designed to be used in series with the load in order to ensure effective voltage clamping. It works on the principle of voltage-varying resistance that varies depending upon the applied voltage. The resistance of the device is minimized when the applied voltage is below the threshold voltage and is increased as the applied voltage increases. As the applied voltage reaches the peak operating voltage of the VDRS10P420BSE, the resistance of the device increases rapidly, providing rapid overvoltage protection and current limiting.

The use of the VDRS10P420BSE for overvoltage protection is one of its main benefits. Its low capacitance and wide operating voltage range are also attractive features. The device is also designed to reduce the response time to overvoltage, allowing it to function quickly and efficiently to protect the components and circuitry it is used with. The device also has a high peak pulse power rating, allowing it to withstand higher surge conditions.

The VDRS10P420BSE is a bidirectional 400-Volt Bidirectional Varistor that provides excellent surge protection for a variety of applications. Its fast response time and wide operating voltage range make it an attractive choice for a wide range of protection applications. Its low capacitance and high peak pulse power rating make it a reliable and cost-effective solution for protecting sensitive equipment from surges and spikes in an electrical circuit.
