Common Mode Chokes are passive electronic components used as inductors for suppressing common mode noise in two-wire systems, such as that caused by electromagnetic interference. TF1714VU-802Y1R0-01 is a common mode choke specifically designed to filter out EMI from high-speed digital systems and reduce the potential of data errors.

Applications

TF1714VU-802Y1R0-01 common mode choke is most commonly used to reduce the effects of radio frequency interference (RFI) in high-speed digital systems operating at up to 3.125GHz. It is also capable of 5A current with 400volts peak voltage. These chokes are ideal for Ethernet applications, home audio systems, data centers, industrial control systems, cable modems, and in medical device applications.

Design

TF1714VU-802Y1R0-01 chokes are designed for common mode noise suppression, ensuring that any noise generated on either line will result in a nearly zero voltage potential between them. These chokes consist of two coil windings, with an integral ferrite core that creates an inductive effect at the operating frequencies. The coils are equally split into a positive and a negative value, eliminating the possibility of leakage. TF1714VU-802Y1R0-01 has an impedance that is wide enough to ensure the common mode noise is spread across the entire frequency band.

Working Principle

When two lines are connected, the common mode choke works by establishing an impedance along the two lines. This impedes the flow of current, so any noise in the form of electrical interference will be reduced. The chokes\' inductive effects also allow for a complementary effect between the two lines. The differential voltage between the two lines\' noise is reduced to nearly zero, resulting in a reduction of the differential mode noise. This helps maintain the integrity of the signals passing through the lines.

Advantages

TF1714VU-802Y1R0-01 common mode chokes are designed to operate reliably at high speeds, reducing errors caused by interference. Additionally, they have a wide operating frequency range and a small size, making them ideal for applications in tight spaces. As the core of the choke is made of ferrite, it is resistant to corrosion and chemical damage, which significantly increases the performance and lifespan of the device.

Conclusion

TF1714VU-802Y1R0-01 common mode chokes are specifically designed for high-speed digital systems and feature a wide operating frequency range and a small size for applications in tight spaces. Additionally, their inductive effect ensures a complementary noise reduction effect between the two lines, which helps maintain the integrity of the signals passing through. The ferrite core composition also increases resistance to corrosion and chemical damage, resulting in improved performance and longer life.
