Common Mode Chokes, also known as line filters, are components commonly used in communication systems and power electronics circuits. They create a barrier between the power source and the protected device or circuit and are designed to inhibit high-frequency noise from affecting the protected equipment. 7446620027 is a common mode choke designed to provide excellent electrical noise suppression in both inductive and resistive loads. It provides superior common mode attenuation over wide frequency ranges, is flame-retardant, and designed for superior reliability.

Application Field

7446620027 common mode chokes are commonly used in AC/DC, DC/DC, and instrumentation power supplies, as well as other power circuits. They are especially beneficial in motor and switching circuits, which can be adversely affected by noise caused by high-frequency or power switching circuits. Additionally, they are used in switching modes, communication circuits, and line interference suppression. They are also used in industrial control circuits, automotive applications, and security systems.

Working Principle

The 7446620027 common mode choke consists of a pair of windings inserted close together on a ferromagnetic core. The two windings are electrically isolated from each other but physically connected to one another to provide a low impedance path for common mode currents. Common mode chokes typically have higher inductance than differential mode chokes as well as a lower DC resistance.

The common mode current flows into one winding and out of the other, the inductance of the choke winding allows the common mode currents to flow, while the ferromagnetic core helps to constrain the core within the winding which increases the effective inductance. This will suppress the common mode noise, allowing only the desired signal to pass through. The 7446620027 is designed to provide excellent common mode interference suppression from 10 kHz to 10 MHz.

The 7446620027 common mode choke is an ideal solution for the suppression of differential and common mode noises in low frequency applications and their excellent performance makes them suitable for sensitive power and instrumentation applications.
