CM9900R-154

Common Mode Chokes, or CMCs, are devices that provide electromagnetic interference (EMI) and noise reduction. They work in a similar manner to filter circuits, but instead of using active components such as amplifiers and transistors, they use passive components such as coils and capacitors to filter out noise and interference. Common Mode Chokes are used in many different industries, but one of the most popular is the CM9900R-154.

The CM9900R-154 is a common mode choke designed to provide common mode EMI/RFI noise reduction in data and power lines for frequencies from 10kHz up to and beyond 50MHz. The CM9900R-154 is particularly well suited for applications where high levels of conducted EMI need to be rejected, as the unit is able to provide 40dB to 50dB of common-to-ground EMI attenuation. It is also capable of handling up to 90 volts, allowing it to be used in a variety of power line applications.

The working principle of the CM9900R-154 is to provide an inductor-capacitor circuit that works as a low-pass filter. It consists of two independently wound coils connected in series. The objective of the CM9900R-154 is to attenuate, or reduce, the levels of common mode noise present on the line. The inductor helps to reduce AM, FM, and pulse-like signals by reflecting back the energy to the source, while the capacitor helps to reduce noise on the power line and in other parts of the circuit.

The CM9900R-154 is designed to be used in a variety of applications. It can be used in power-line applications such as computer systems, telecom equipment, power generators, and uninterruptible power systems. It can also be used in signal-line applications such as in industrial control systems, variable speed drives, audio and video equipment, and medical and lab equipment. Finally, it can also be used in low-voltage DC-biased applications such as on security and building automation systems.

The CM9900R-154 is a great choice for applications requiring a high level of common mode noise attenuation. It is designed to provide an effective noise-reduction solution with a robust design that enables it to handle a range of conditions and be used in a variety of different applications.
