Additional Details

The AN5521 common mode choke is constructed using high-quality materials to ensure reliable performance and long lifespan. It offers high impedance at high frequencies, effectively suppressing common mode noise. The low DC resistance minimizes power loss, while the high rated current allows for use in high-current applications. These chokes are available in various sizes and configurations to suit different application requirements. Common mode chokes work by attenuating noise that is common to both lines in a balanced circuit, while allowing the desired differential signal to pass through with minimal attenuation. This is achieved by winding the wires of the signal lines around a common core. The AN5521 is typically used in applications where EMI regulations must be met, or where noise suppression is critical to the proper function of the electronic device.
