Common Mode Chokes

A B82793C0476N265 Common Mode Choke is a type of electronic component which, when applied in electric circuits, allows the alternating current (AC) component to move between the hot wire and the neutral wire within the device, while blocking the direct current (DC) component. In other words, it is used to filter out the high-frequency components of the circuit, leaving only the lower frequency components for higher performance. The choke can reduce the transmission noise by up to about 90%.

Application Field

Common Mode Chokes are useful in many types of applications. They are commonly used to suppress noise and other electromagnetic interference (EMI) from power supplies, motors, transformers, relays, and other circuit elements. They can help to improve the signal-to-noise ratio of an electrical device, as well as increase its stability and efficiency. Common Mode Chokes are also popular in medical, automotive, and aerospace applications, where they are used to prevent unwanted electrical noise.

Working Principle

Common Mode Chokes operate on the principle of inductance. An inductor consists of a coil of wire which creates a magnetic field when a current flows through it. By using this magnetic field, a Common Mode Choke creates an impedance which blocks out direct current while allowing alternating current to pass.

Because Common Mode Chokes have a low impedance to AC signals, they are highly effective at reducing EMI. This is because EMI is caused by high frequency signals which have a high impedance to the choke. By blocking the high frequency signals, the choke allows only the lower frequency signals to pass, resulting in better performance.

Conclusion

Common Mode Chokes are a type of electronic component which allow alternating current (AC) to flow between the hot wire and the neutral wire, while blocking the direct current (DC) component. They are often used to filter out high-frequency noise signals, resulting in improved signal-to-noise ratios, as well as increased stability and efficiency. Common Mode Chokes operate on the principle of inductance, using a coil of wire to create a magnetic field which blocks out the direct current signals. They are popular in many types of applications, including medical, automotive, and aerospace.
