Common Mode Chokes

Common Mode Chokes (CMC) are electrical components consisting of wire windings that are designed to reduce the amount of electromagnetic interference (EMI) created by electrical devices operating at high frequencies, usually greater than 100MHz. In particular, they are effective in suppressing conducted disturbances on the power and data lines of products operating within the higher frequency ranges.The TCM2010-201-4P-T application field and working principle is outlined below.

Application Field

The TCM2010-201-4P-T Common Mode Choke is used for compliance with CISPR 35 Class A conducted emissions limit standard. The TCM2010-201-4P-T features an applicable frequency range of 100kHz to 1GHz and is suitable for printed circuit board mounting.

Working Principle

The TCM2010-201-4P-T Common Mode choke utilizes two sets of windings on a single core to reduce EMI conducted noise. It is constructed with two line cores that provide a high impedance in double-common-mode to attenuate conducted emissions in the resulting frequencies. The double-common-mode reduces the amount of noise conducted from the source device onto the power lines.The choke has two sets of windings connected in such a way that they generate an inductive reactance. This reactance (or impedance) reduces and/or delays the amount of noise conducted on the power lines. The result is lower and fewer EMI issues due to reduced noise on the lines.The TCM2010-201-4P-T Common Mode Choke is a Class A component that provides effective noise reduction and performance in the 100 kHz to 1 GHz frequency range. It is specially designed for use in low-voltage application and is ideal for applications such as switch mode power supplies, DC/DC converters, motor drives, and similar devices.

Conclusion

The TCM2010-201-4P-T Common Mode Choke is an effective and cost-efficient way to reduce EMI conducted noise in higher frequency applications. This choke provides high levels of attenuation in the 100kHz to 1GHz frequency range and is suitable for use in a variety of applications such as switch mode power supplies, DC/DC converters and motor drives. The use of this choke can help to meet the CISPR 35 Class A conducted emissions limit requirements and make products more compliant with EMI regulations.
