Common mode chokes, also known as common mode filters, are wideband inductors widely used in noise suppression applications in RF and other electronic systems. The TF3435VU-301Y20R0-01 is one such filter, developed by Texas Instruments for use in high-speed differential signal lines used in WLAN, WPAN, and other applications. This device integrates two high-efficiency Common Mode Chokes with an integrated transmission line transformer, providing superior performance with low profile, leading-edge technology. This device is designed to reduce the noise produced by differential signals by filtering out the common mode noise.

Application Field

The TF3435VU-301Y20R0-01 Common Mode Choke is designed for use in a wide variety of applications due to its high efficiency and low profile. This device is typically used for suppressing common mode noise in WLAN, WPAN, and other high-speed differential signal lines. It is also used for eliminating EMI noise generated by power lines. This filter is ideal for use in industrial, automotive, consumer, and mobile devices because of its high efficiency. The low profile of the device also makes it suitable for use in space constrained environments, such as in embedded systems.

Working Principle

The TF3435VU-301Y20R0-01 operates on the principle of inductive reactance. This principle states that when an alternating current passes through an inductor, it creates an opposing magnetic field, which causes a voltage to be generated across the inductor. This voltage is opposite in direction to the applied voltage and is in phase with the current. This opposing voltage reduces the amount of current which is allowed to pass through the inductor, thereby attenuating any high-frequency noise present in the signal. The TF3435VU-301Y20R0-01 utilizes two common mode chokes which are integrated into a single transmission line transformer, providing superior common mode noise suppression.

The TF3435VU-301Y20R0-01 Common Mode Choke also incorporates a low-loss circuit design which maximizes the signal integrity of the transmission line while providing high-efficiency common mode noise suppression. This reduces the signal degradation which can occur in the presence of high levels of noise and can increase the overall performance and reliability of the system. The TF3435VU-301Y20R0-01 is also designed with robust electrical parameters to ensure reliable operation in a wide range of operating environments.

Conclusion

The TF3435VU-301Y20R0-01 is a high-efficiency Common Mode Choke which is designed for use in a wide variety of applications. This device operates on the principle of inductive reactance which helps to attenuate high-frequency noise. The low-loss circuit design of the device also ensures that it is able to reliably filter out both common and differential mode noise. This makes it suitable for use in embedded systems, industrial, automotive, and consumer applications. Additionally, the integrated transmission line transformer allows the device to minimize the overall loss of transmitted signals while providing superior common mode noise suppression.
