Common Mode Chokes (CMCs) are components that allow the passage of direct currents (DCs) while blocking alternating currents (ACs), and play an important role in EMI suppression. TF2326VU-102Y6R0-01 CMCs are designed with an iron core loaded with two types of core materials, such as two permalloy tapes, one Ni-Zn ferrite core surrounding it as well as two CMC coils that are wound around the outer core. It is designed specifically to provide maximum suppression against EMI in high speed transmission lines.

Application Fields

The TF2326VU-102Y6R0-01 CMC is mainly used for suppressing EMI noise in high speed serial communication lines, such as USB (universal serial bus), PCIe (Peripheral Component Interconnect Express) and SATA (Serial ATA). It can be used in PC motherboards, automotive gadgets, electronic toys, digital and analog communication systems in addition to power converters.

Working Principles

TF2326VU-102Y6R0-01 CMCs suppress EMI caused by current surges by filtering the troublesome frequencies in the signal and allowing only desired frequencies to pass through. The filtering effects are primarily due to the properties of the two permalloy tapes standing in the middle of the iron core as well as the Ni-Zn ferrite core surrounding it. The CMC only suppresses EMI noise and does not pass through common-mode signals. As a result, it works as a functional part in suppressing noise generated in communication systems.

The CMC is able to filter out high frequency noise currents to suppress EMI noise due to its intricate and premium inner structure. It is characterized by the fact that a cylindrical core is surrounded by a cylindrical electrical winding. The two coils are connected in series in the common-mode direction, and the number of turns of the two coils are generally the same. As the current passes through, the two coils will generate magnetic fields in the same direction. With this structure, the cancelation of electromagnetic forces occur, which allows the device to achieve the suppression effect on EMI noise.

In addition, the CMC also features excellent high frequency characteristics. It has very low insertion loss and ensures very low current leakage. This provides an excellent combination of wide band noise suppression and high frequency characteristics. The CMC is also capable of producing very low inductance, which can fit the basic requirements of modern electronics.

Overall, the TF2326VU-102Y6R0-01 is a reliable CMC designed for suppressing EMI noise in high-speed serial transmission lines. Its intricate and premium inner structure makes it capable of filtering out undesirable high frequency noise currents, and its excellent high frequency characteristics ensure an excellent combination of wide-band noise suppression along with its low inductance.
