Common Mode Chokes are electromagnetic components which are typically enclosed in ferrite or other types of magnetic cores in order to block the transfer of electromagnetic interference from one circuit to another. Common Mode Chokes are a type of electromechanical device that actively filters out high frequency components in a signal, increasing its immunity to EMI. Common Mode Chokes are widely used in various applications including high voltage, high current, power electronics, and communications.

CM1011R-755 is a new type of Common Mode Choke developed by Hirosaki Electronics. It is a transformer-like device that can be used to block the EMI between two circuits. The CM1011R-755 is designed to work with both AC and DC currents. Its high-performance magnetic core makes it ideal for applications where precision impedance matching and high inductance is needed.

The main application field of the CM1011R-755 is in DC-DC converters, where a relatively high voltage input is necessary, as it can handle up to 125V. Additionally, it can provide a very low-noise environment for high frequency switching applications such as power line switching, motor control, and motor speed control. It can also be used for various analog signal conditioning applications, as it can provide a low-pass filter response with high attenuation and good transmission characteristics.

The working principle behind the CM1011R-755 is similar to that of any passive electromagnetic component. The components inside the CM1011R-755 interact with each other in order to block the transfer of electromagnetic interference from one circuit to another. It is made up of two coils, usually surrounded by a ferrite core, that are wound in opposite directions. When DC current is passed through the coil, the core creates a magnetic field generated by the current. This magnetic field then interacts with the other components inside the CM1011R-755, which are either coils or resistors, in order to filter out the EMI.

The CM1011R-755 can also be used as AC line filters, where it is capable of dissipating power losses and providing smooth di/dt control. In this application, the CM1011R-755 is used to limit the high frequency energy and reduce various levels of interference, such as conducted and radiated emission, and line-to-line and line-to-ground voltage.

In addition, the CM1011R-755 can also be used in high voltage isolation applications, such as motor control. In this application, the CM1011R-755 can be used to provide electrical safety between the high voltage and low voltage circuits. It can also be used as noise reduction filters, as it can reduce the amount of high frequency components present in the signal. This can improve the signal-to-noise ratio, making the system more reliable and efficient.

The CM1011R-755 is highly compact in size and can be easily mounted, making it perfect for applications where space is limited. It is also available in a range of different sizes and versions, making it suitable for a variety of applications. Additionally, the CM1011R-755 has a wide operating temperature range, making it suitable for both indoor and outdoor applications.

In summary, the CM1011R-755 is a versatile Common Mode Choke that is capable of providing a broad range of applications. Its magnetic core design makes it an ideal solution for DC-DC converters, AC line filters, high voltage isolation, and noise reduction applications. The CM1011R-755 can also be used in motor control and motor speed control, as it can provide reliable protection against EMI and provide improved signal-to-noise ratio. Its compact size makes it an ideal choice for applications where space is limited, and its wide operating temperature range makes it suitable for both indoor and outdoor installations.
