Common Mode Chokes, also known as CM chokes, are used to reduce the noise-inducing capacitive radiation from high-frequency switched signals. They are typically used in power circuits and tight-tolerance programs requiring low Common Mode Current (CMC). In such applications, CM chokes are usually integrated with other components within the power conversion system, such as EMI filters, EMI shields, crystal oscillators, and inductors. CM chokes are suitable for many technologies, ranging from DC/DC converters to process control and microprocessors.

The CM0805A371R-10 is a type of Common Mode Choke from Murata Manufacturing, released in March 2019. This device is part of the Murata slim MLCC package family, and is suitable for use in high integrity, sensitive electronic systems. It is suitable for both DC and AC applications – CMC values can range up to 10 uA, isolation voltages can range up to 1000 VDC, and impedance can range from 0.2 to 10 kΩ.

The CM0805A371R-10 common mode choke works by using an inductor configuration that reduces EMI frequencies by attenuating high frequencies while allowing low frequency signals to pass through. It is designed to reduce the capacitive radiation that is often generated from high-frequency switched signals, thereby improving the system’s overall noise performance. Additionally, the combination of the inductor and the capacitor in the choke reduces noise to a much lower level than can be achieved with a single component solution. As a result, any noise generated by the circuit is less likely to interfere with other signals in the system.

Murata Manufacturing’s CM0805A371R-10 can be used in various applications. It is particularly well-suited for electrical switch apparatus, DC/DC converters, and power supplies. Additionally, the CM0805A371R-10 can be used for power converters, automotive spark plugs and accessories, microprocessor control circuits, and medical devices.

Overall, CM chokes like the CM0805A371R-10 are essential components for modern, high-frequency circuits. They not only reduce the capacitive radiation emitted from high-frequency switched signals, but also improve the system noise performance. Furthermore, They can also be used in a wide variety of applications, from automotive spark plugs to medical devices. Therefore, the CM0805A371R-10 common mode choke is a great option for anyone looking to reduce EMI in their circuit and improve their system’s overall performance.
