Common Mode Chokes and the TCK-121

Common mode chokes are designed to reduce the noise and interference caused by through-hole mounted transmission lines. They serve to eliminate the need for additional shielding and insulation around sensitive components like wires and circuit boards. The TCK-121 is a common mode choke designed to reduce the amount of common mode noise that is produced in signal lines.

What are Common Mode Chokes?

Common mode chokes are filters that are used to reduce common mode noise in signal lines. These filters are comprised of several inductors and capacitors which are connected together in series or in parallel. The resulting combination of components acts as a filter that blocks the flow of electrical noise and interference. The goal of these filters is to decrease the amount of noise caused by through-hole mounted transmission lines.

The TCK-121 Application

The TCK-121 is a common mode choke developed to reduce the amount of noise caused by through-hole mounted transmission lines. The TCK-121 is designed with multiple coils, capacitors, and resistors and works in the range of 1.5 to 3.2 GHz. The filters used to reduce the common mode noise are extremely effective and have been found to reduce the amount of common mode noise by as much as 50 dB. The TCK-121 is well suited for a variety of applications including but not limited to cellular base stations, remote radio heads, cell towers, and medical devices.

The TCK-121 Working Principle

The TCK-121 is designed with multiple coils, capacitors, and resistors to eliminate the noise created by through-hole mounted transmission lines. The coils are designed to reject any common mode noise caused by the transmission lines. The capacitors provide a low-impedance path between the coils and the ground while the resistors help to increase the effectiveness of the choke. By combining these components the preferred design characteristics of the TCK-121 are met.

Conclusion

Common mode chokes such as the TCK-121 are designed to reduce the amount of noise caused by through-hole mounted transmission lines. The TCK-121 is a common mode choke specifically designed to reduce the common mode noise that is produced in signal lines. The filters that are used in the TCK-121 are extremely effective and have been found to reduce the amount of common mode noise by as much as 50 dB. The TCK-121 is well suited for a variety of applications and is designed to have the desired design characteristics for filtering out common mode noise.
