Common Mode Chokes, or CM chokes, are used in a variety of applications to block or filter electromagnetic interference (EMI) and provide protection in sensitive applications. CM chokes are designed to handle interference at a range of frequencies depending on the application. The CM6149-684 is a miniaturized, wide frequency range common mode choke designed for applications requiring high impedance over a wide range of frequencies. The CM6149-684 is available in an 8-pin DFN package, making it an ideal solution for low-profile and space-constrained applications.

Common mode chokes are passive devices that are used to block or suppress common-mode noise that is generated in electrical circuits. Common-mode noise is the undesired, unwanted noise that is induced onto a signal line and is of equal and opposite polarity on the two signal conductors. This noise can produce errors in the accompanying circuitry and lead to harmonic distortion and other errors.

The CM6149-684 is designed to provide maximum common-mode noise suppression, with up to 70dB of attenuation over a wide range of frequencies. It is rated for up to 250mA of ripple current, and has an operating temperature range of -55°C to +125°C. The device is characterized for impedance from 0.1MHz to 1GHz and is supplied in an 8-pin DFN package.

The working principle of the CM6149-684 is based on its ability to reject common-mode noise over a wide range of frequencies. The device utilizes an array of ferrite beads that act as small inductors, which are arranged in a configuration that provides the maximum potential to reject common-mode noise. The beads are connected in series, with each bead connected to the outer two terminals which are in turn connected to the signal lines. The central two terminals are connected together, and this provides the differential mode return path for the signal.

The CM6149-684 can be used in a variety of applications requiring high common-mode noise suppression. It is ideal for use in industrial, instrumentation, audio, and automotive applications. The device can also be used in communication systems, power supplies, and other consumer electronics where high common-mode suppression is required. The device is also suitable for both high and low voltage applications.

The CM6149-684 is an ideal solution for reducing common-mode noise in a variety of applications. The device utilizes ferrite beads to provide the maximum possible common-mode noise rejection, and is available in a low-profile 8-pin DFN package, making it an ideal choice for space-constrained applications. The device is rated for up to 250mA of ripple current and is capable of providing up to 70dB of attenuation over a wide range of frequencies, making it an ideal choice for applications requiring high common-mode suppression.
