Common Mode Chokes (CMCs) are electric filters used to reduce the amount of EMI (electromagnetic interference) in a circuit. The CM6149R-683, made by Sumitomo Electric Industries, is a common mode choke designed for general purpose EMI filtering applications. It has a low current DC resistance and a high inductance which makes it ideal for reducing both differential mode and common mode noise in a circuit. This article will discuss the applications of the CM6149R-683 and its working principle.

Applications

The CM6149R-683 is a versatile common mode choke which can be used in a wide range of applications. It is especially effective for reducing differential noise and interfering signals that are common in power supplies, motor drives, and communication systems. It can also be used in DC Power, Audio, Telecommunications circuits, and Microcontroller systems. The low current DC resistance of the CM6149R-683 also makes it a good choice for audio and video applications where minimal power loss is desired. Furthermore, it has the ability to reduce common mode noise in low and medium current circuits.

Working Principle

The CM6149R-683 is an inductive component which functions primarily by creating an inductive reactance in a circuit. This type of reactance limits the amount of AC current that can enter or leave the circuit and reduces the amount of EMI. The CM6149R-683 consists of two identical windings which are placed in close proximity to one another. The windings are arranged so that when an AC signal passes through both windings, the two signals are out of phase with each other. This out-of-phase signal creates an inductive reactance which reduces the amplitude of the AC signal and reduces the amount of EMI.

The CM6149R-683 also has a unique design which reduces both differential mode and common mode noise. It has two sets of windings, one for each type of noise. This design allows the CM6149R-683 to reduce both types of noise without having to compromise on the amount of inductive reactance. The fact that it can reduce both types of noise makes it a better choice for applications which require a higher degree of noise suppression.

Conclusion

The CM6149R-683 is a versatile and effective common mode choke which can be used to reduce EMI in a wide range of applications. It is especially suitable for applications that require a high degree of noise suppression, such as power supplies and motor drives. The CM6149R-683 operates by creating an inductive reactance in the circuit, which reduces the amplitude of the AC signal and reduces the amount of EMI. The unique design allows it to reduce both differential mode and common mode noise without sacrificing performance. All in all, the CM6149R-683 is an excellent choice for any application that requires a high degree of noise suppression.
