Common Mode Chokes - CM3421Y600R-10 Application Field and Working Principle

Common mode chokes consist of two or more windings and are designed for overvoltage protection, line interface, and electromagnetic immunity functions. CM3421Y600R-10 common mode chokes are specifically designed to provide excellent common mode noise suppression over a wide frequency range. The chip size of this series of common mode choke is only 8.3x 10.2 mm, making it very suitable for high-density mounting.

Application Field

CM3421Y600R-10 common mode choke are typically used in network communication device, where common mode noise suppression is needed, such as network switches, routers, DSL modems, optical network adaptors, and cable modems. In the current market, these devices usually require data rates of up to 10 Gbits/s to meet the need of today\'s high-speed networks. The CM3421Y600R-10 common mode chokes feature impedance values of 6 ohms, 10 ohms, and 15 ohms, and is capable of suppressing common mode noise from 100KHz to 500 MHz. The combination of these features ensure that this series of common mode chokes can meet the need of current high speed networks. Additionally, the use of advanced materials provides excellent surge and overvoltage protection which is especially useful in protecting devices from potential damage caused by surge current or overvoltage.

Working Principle

Common mode chokes are effectively inductors with two windings. They are designed to provide an impedance between the two windings and prevent unwanted radio frequency or AC interference from flowing between the two windings. This is usually done by having each winding the same size to ensure a symmetrical field in the electromagnetic core, thus forcing any RF or AC noise to flow through the choke instead of the two windings. The inductance of the choke causes the noise to be suppressed by raising the impedance of the noise to an unnaturally high level. Additionally, as the frequency increases, the impedance of the choke increases as well, making it even more effective against high frequency noise.

CM3421Y600R-10 common mode chokes are designed with advanced materials to provide superior performance in network communication applications. The high impedance combined with the small footprint makes the CM3421Y600R-10 an ideal choice for suppressing common mode noise in high speed communication networks. The surge protection feature also ensures that the devices connected are protected against potential damage from surge current or overvoltage.
