Common Mode Chokes - TF1714VU-202Y2R0-01 application field and working principle

Common Mode Chokes (CMC) are electrical components used in circuits to block or limit the amount of common mode current flowing through the circuit. This helps in ensuring that the system remains secure from any adverse affects of the common mode current. This article discusses the features and application of one such type of CMC, namely the TF1714VU-202Y2R0-01.The TF1714VU-202Y2R0-01 is designed to provide high quality filtering performance for high frequency and line-level power applications. The choke contains a unique ferrite core and core-less structure which offers excellent common mode noise rejection characteristics. It is designed to provide very low insertion loss across the rated frequency range. The choke is rated for a maximum working voltage of 600 Volts peak-to-peak and a minipulation temperature range of -55°C to +125°C.The TF1714VU-202Y2R0-01 is well-suited for applications in the audio, video and RF industry. It helps in filtering out signal interference from AC, DC, as well as common mode currents. This helps in reducing the overall noise levels in the system and improving system performance. The choke also helps in eliminating any ground loops in the circuit, thus preventing any damage to sensitive components in the circuit.The TF1714VU-202Y2R0-01 is also designed for low power loss applications, such as in line filtering of RF and audio spectrum. It provides very low insertion loss across the rated frequency range, thus helping in transmission of signals. The choke also provides good transient suppression characteristics, which helps in reducing the rate of voltage rise when subjected to high voltage surges.The working principle of the TF1714VU-202Y2R0-01 CMC is based on the principle of mutual inductance. The choke consists of two inductors which are placed in series with each other. The inductors are wound with a core made from specially formulated ferrite material which provides high impedance to both common mode and differential mode noise and signals. The CMC works by creating an electromagnetic field between its two inductors. This field interacts with both common mode and differential mode noise and signals and creates an opposite phase current flow. This opposed current flow reduces the power and current of the common mode current, thus limiting its effect on the system.In summary, the TF1714VU-202Y2R0-01 is an effective Common Mode Choke designed for a wide range of high frequency and line-level power applications. It offers excellent noise rejection performance and helps in eliminating any ground loops in the circuit. The choke also provides very low insertion loss across the rated frequency range. Lastly, its unique configurations and working principle based on the principle of mutual inductance makes it an ideal choice for audio, video and RF applications.
