Common Mode Chokes

Common mode chokes, also referred to as common mode inductors, can be utilized to attenuate any common mode currents in a power supply circuit, and are implemented in applications that require high-speed switching responses, such as the RN202-0.3-02-22M. Common mode chokes are used to reduce the amount of noise produced in power supplies.

Application Field

The RN202-0.3-02-22M is a type of common mode choke. Common mode chokes are frequently applied to decouple the power supply from ground, filter out switching noise, reduce radio interference, and reduce crosstalk in sensitive applications such as audio or communications systems. Common mode chokes are most frequently used to filter out high frequency interference while allowing for proper signal transmission.

Working Principle

The RN202-0.3-02-22M works by blocking common mode currents while allowing differential currents through. These common mode chokes act like a gate, blocking interference and noise from entering or leaving the circuit. Common mode chokes are relatively large, high impedance windings that are connected around a ferrite core, the shape of which is optimized to minimize inductance values. The windings are not connected directly together, but rather to a source and a ground separately, resulting in the blocking of common mode currents.

Common mode chokes have a very low insertion loss, allowing them to effectively reduce noise without reducing signal strength. The magnetic flux generated by the inductor channels interference and noise away from the signal, which is then blocked by the common mode choke. The rate at which noise is reduced is determined by the size and shape of the ferrite core, the number of windings, and the type of winding material.

Conclusion

The RN202-0.3-02-22M is an effective common mode choke that can be used to reduce noise in high-speed applications. Common mode chokes comprise of a ferrite core and a winding, and they act as a filter to block common mode currents while allowing differential currents to pass through. The size and shape of the ferrite core, the number of windings, and the type of winding material are critical to its performance, and ultimately dictate the performance of the RN202-0.3-02-22M common mode choke.
