B72660M0131K072 Circuit Protection

A varistor is a voltage-dependent, nonlinear electronic component which limits excessive voltages that may develop on an electrical power grid. The B72660M0131K072 is an example of a varistor and can be classified as belonging to the TVS - Varistors, MOVs family.

By design, when an excessively high voltage exceeds a specified threshold, the B72660M0131K072 will quickly reduce this voltage down to a safe level, making it a crucial electronic component for electrical and automotive industries demanding robust power conditioning and protection.

The B72660M0131K072 is mainly used for overvoltage protection and to limit the voltage of alternating currents (AC) and direct currents (DC) on residential, industrial, and commercial markets. Its main applications include surge suppression on household appliances such as TVs, monitors, computers, and copiers.

The B72660M0131K072 has a varistor voltage rating of 7.2V and can withstand maximum varistor surge voltage up to 500. Additionally, its Power Dissipation Rating (PDR) is 130W. In comparison to other varistor models, the B72660M0131K072 offers a high power dissipation rating and can handle higher surge voltages.

In order to understand how the B72660M0131K072 works, one needs to understand the concept of resistance. Resistance is a measure of the difficulty one faces when attempting to send an electrical current through a material. Different materials exhibit different resistances. For example, copper has a very low resistance compared to iron and other materials.

The B72660M0131K072 contains a special ceramic material which exhibits an extremely high resistance to electric current.This high resistance will resist the flow of electricity and cause an increase in voltage across the device. When the voltage reaches a certain level -- the varistor voltage -- the crystal material starts to become conductive, allowing electricity to flow through it, and resulting in a sharp decrease in voltage.

In summary, the B72660M0131K072 is an example of a varistor belonging to the TVS - Varistors, MOVs family and is mainly used for overvoltage protection and to limit the voltage of AC and DC on residential, industrial, and commercial markets. Its main applications include surge suppression on household appliances such as TVs, monitors, computers, and copiers. It has an Varistor Voltage Rating of 7.2V and can withstand maximum varistors surge voltage up to 500, and it can handle higher surge voltages thanks to its high power dissipation rating of 130W.
