Common mode chokes, also known as common mode inductors, are used to eliminate or reduce electromagnetic interference (EMI) from high-frequency signals traveling along a power line. The TF2514VU-101Y5R0-01 is an example of a common mode choke. In this article, we will discuss the application field of common mode chokes, and other information about the TF2514VU-101Y5R0-01 choke, including its working principle.

What Are Common Mode Chokes Used For?

Common mode chokes are used to reduce EMI from electrical power lines. They work by creating a high-frequency impedance across the power lines which blocks the EMI from passing through. Common mode chokes are used in a variety of industrial applications, with a few key applications being: power supplies, surge protectors, UPS systems, motor controllers, and data transmission systems.

Common mode chokes can also be used in home or office electrical wiring to reduce EMI from radio broadcasts and other sources. In addition, they are often used in telephone systems to reduce interference on the line. Common mode chokes are also used in automotive electronics, such as ECUs in engine control units.

TF2514VU-101Y5R0-01 Common Mode Choke Specifications

The TF2514VU-101Y5R0-01 is a common mode choke designed for use in power lines and telephone systems. It has a rated filter bandwidth of 19 kHz to 800 MHz, making it well suited for use in a wide range of electronics applications. It also has an 0.9 ohm DCR for improved impedance characteristics. The maximum current rating is 1.2 amps and the maximum voltage rating is 400V. It has an operating temperature range of -40 degrees Celsius to 85 degrees Celsius.

Working Principle of TF2514VU-101Y5R0-01 Common Mode Choke

The TF2514VU-101Y5R0-01 common mode choke is a series-resonant circuit consisting of an inductor and a capacitor. The inductor and capacitor create a resonance, which creates a high-frequency impedance across the power lines. This impedance blocks EMI from passing through the power line. The capacitor also acts as an RF filter, which helps to reduce the intensity of the EMI before it is blocked.

In addition, the TF2514VU-101Y5R0-01 has an internal EMI filter which further reduces the intensity of the EMI before it reaches the choke. This helps to improve the performance of the choke, as the lower the intensity of the EMI, the less impedance is required to block it.

Conclusion

Common mode chokes, such as the TF2514VU-101Y5R0-01, are used to reduce or eliminate EMI from power lines and telephone systems. They work by creating a resonance, which creates a high-frequency impedance across the power lines, blocking the EMI. In addition, the TF2514VU-101Y5R0-01 has an internal EMI filter which further reduces the intensity of the EMI before it reaches the choke.
