TVS - Varistors, MOVs are key components used in the electrical and electronic comfort industry. They are used in several applications for low voltage protection, overvoltage protection, and surge protection. The V2AF118C400Y1FDP is a popular TVS - Varistor, MOV designed for use in applications like Computer Motherboards, Data Communications, and Audio/Video Systems. It offers excellent EMI/RFI protection across the bandwidth from 0-4GHz, with a peak acute withstand voltage of 500V.

The key features of the V2AF118C400Y1FDP include low capacitance (0.05pF), low internal resistance (1 ohm ), and a fast response time (less than 2ns). It also provides superior surge-protection capability, with the ability to absorb up to 1250A of current. The V2AF118C400Y1FDP is designed for use in a wide variety of applications, including industrial, medical, electronics, and automotive systems.

Varistors, also known as Metal-Oxide Varistors (MOVs), are components that can detect and absorb excessive electrical energy that is generated during overvoltage or surge events. They are made from a metal oxide material that has a high dielectric constant – this means that when voltage is applied, it causes the material to become highly conductive. In effect, the metal oxide material acts like a resistor, allowing the pressure of the voltage to dissipate to the ground.

When an overvoltage or surge occurs, the varistor can absorb the energy by changing its resistance. The resistance of the varistor changes as the voltage reaches the peak and the current begins to dissipate. At lower voltages, the resistance of the varistor is high and it acts as an open circuit. As the voltage rises, the resistance begins to decrease and the current can begin to flow. This means that it can absorb the surge current and protect the components in the system from damage.

MOVs have a low clamping voltage, making them ideal for protection against low-voltage surges. This type of surge protection is often used in sensitive electronic components, such as computer motherboards, data communication systems, and audio/video systems. When using the V2AF118C400Y1FDP, it is important to ensure that the rated current surge capability is sufficient for the application. This is because MOVs cannot absorb an unlimited amount of current, and will eventually fail to protect the system if the current goes beyond its rated capability.

The V2AF118C400Y1FDP provides excellent protection in a wide variety of applications, as it can quickly absorb the energy generated by a surge. Its low capacitance and internal resistance also make it ideal for use in EMI/RFI immunity applications. The fast response time ensures that the surge current can be absorbed quickly, minimising the risk of damage to sensitive components. The V2AF118C400Y1FDP is an excellent choice for efficient surge protection in a wide variety of applications, and is a reliable and economical solution for protecting electronic devices from high-voltage surges.
