Varistors, also known as voltage-dependent resistors (VDRs), are one of the most important components in power supplies and other electronic devices. They are used to protect circuits from overvoltage-induced failure related to lightning strikes, power surges, and other external transient-voltage events. The AMCV-2220H-5R5-T is a type of varistor that provides excellent protection against a wide range of voltage and power surges. This article will discuss the application fields of the AMCV-2220H-5R5-T and its working principle.The AMCV-2220H-5R5-T is a part of a popular series of varistors made by Amphenol Advanced Sensors. This type of varistor is classified as “Metal-Oxide Varistor,” meaning it is a three-terminal electro-component that utilizes a metal-oxide layer to control the flow of current. It has a surge current rating of 5A and an operating voltage of 15V. This type of varistor is most commonly used in applications requiring protection from electrical noise, overvoltage transients, and ESD events. It can also be used in pulse protection for automotive electronics, electric motors, drives, and solar systems.The working principle of the AMCV-2220H-5R5-T can be understood by looking at how it behaves when subjected to an electrical overstress (EOS). When a transient overvoltage that is greater than the varistor\'s rated voltage is applied to the device, the metal-oxide layer begins to conduct current. This process results in the varistor\'s impedance rapidly decreasing as the voltage increases, allowing for efficient protection of the circuit from overvoltage. The working principle of this varistor is similar to that of other MOVs.When using the AMCV-2220H-5R5-T, it is important to keep in mind that the device should be mounted securely with a suitable mount. The device should also be subjected to a sufficient number of conditioning cycles, which will allow for the varistor to reach its optimal performance. Finally, it is essential to make sure that the EOS rating of the device is at least two times greater than its expected operating voltage.In summary, the AMCV-2220H-5R5-T is a type of metal-oxide varistor that provides excellent protection against a wide range of voltages and power surges. It is most commonly used in applications that require protection from electrical noise, overvoltage transients, ESD events, and pulses. The working principle of this type of varistor involves the metal-oxide layer conducting current when a transient overvoltage that is greater than its rated voltage is applied. It is important to ensure that the device is mounted securely and subjected to sufficient conditioning cycles.
