Common mode chokes (CMCs) are components that help suppress electromagnetic interference (EMI) from communication lines and electronic signals. The TF1815HU-302Y2R0-01 is a common mode choke used in a variety of applications. Understanding the application field and working principles of this component can help engineers assess if it is suitable for their specific project.

Application Field

The TF1815HU-302Y2R0-01 is a high current common mode choke, which is available in four different sizes: 0615, 1815, 3320 and 3932. It has a current carrying capacity ranging from 6A to 75A, and is suitable for applications involving high frequency and high voltage. It is used to suppress noise emitted from high power electronic devices and interfere with communication lines. It can also be used to reduce EMI radiation, which can help to meet some EMI compliance specifications.

TF1815HU-302Y2R0-01 is commonly used in automotive applications, such as power module, DCDC converters, eddy current suppression, motor drive, and HBridge applications. It is also suitable in communication applications, including CANbus, 10/100 Base-T Ethernet, Fibre Channel, RS-485, and other serial lines, as well as in home appliance and consumer electronics circuits. It is available for use in temperatures ranging from -40°C to +110°C.

Working Principle

Common mode chokes work by limiting the amount of common mode noise present on a cable. The TF1815HU-302Y2R0-01 is constructed from a core and two windings. The core is surrounded by the two windings, which act independently to impede the passage of common mode noise. The two windings are wound in opposite directions so that the external magnetic fields of each winding counteract each other. This limits the amount of common mode noise that is able to pass through the choke.

The two windings of the TF1815HU-302Y2R0-01 are also connected in parallel in order to increase the current carrying capacity of the choke. This parallel connection increases the impedance of the choke, thereby reducing the amount of noise that can pass through it. Overall, the choke works to suppress common mode noise, reduce EMI radiation, and create a more reliable connection between communication lines and electronic signals.

Conclusion

The TF1815HU-302Y2R0-01 is a common mode choke that is suitable for a variety of applications, ranging from automotive to communication. It is constructed from a core and two windings and works by limiting the amount of common mode noise present on a cable. By understanding the application field and working principles of this component, engineers can assess if it is suitable for their specific project.
