V660LT80CPX2855

A varistor, also known as a voltage-dependent resistor (VDR), is an electronic component with the ability to modify the voltage that is applied across its terminals in order to regulate the flow of current. Varistors are found in many types of electronic equipment, including radios, televisions, and computers. The V660LT80CPX2855 is a surface-mount varistor manufactured by Fenghua Electronics Company. This series of varistors has a broad range of applications, from overvoltage protection and energy absorption to harmonic filtering and medical equipment.

The V660LT80CPX2855 varistor is a low capacitance device which can offer excellent protection from transients and overvoltage. It has an operating voltage range of 6~900V, a power dissipation of 8.0J, and a non-linear capacitance of 0.0029pF. Its rated current is 140mA with a maximum peak pulse current of 600A.

The principle of operation of the V660LT80CPX2855 varistor is based on its non-linear capacitance. During normal operation, the voltage across the terminals of the varistor remains constant, but when an overvoltage is applied, the capacitance decreases, reducing the flow of current. This mechanism allows for the device to protect circuits from transients and surges. In addition, the device can also be used to reduce the impact of harmonics and maintain the desired voltage for sensitive components.

The V660LT80CPX2855 varistor can be used in a wide range of applications, including overvoltage protection, filtering, and surge absorption. It can be used in the telecommunications industry for providing protection against lightning strikes and keep transient and noise levels low. It can also be used in audio and video systems as a component of transient voltage suppression (TVS) circuitry which helps to reduce distortion and minimize interference. Medical equipment, such as dialysis machines, can also use this device for overvoltage protection by providing a stable operating voltage.

In conclusion, the V660LT80CPX2855 varistor is a versatile device offering numerous applications, ranging from energy absorption to harmonic filtering. It can provide reliable protection in a variety of electronic circuits and devices, and can be used in a wide range of industries, from telecommunications to medical equipment. Its mechanical characteristics and low capacitance make it suitable for surface mounting, allowing it to be used in a wide range of applications.
