Common Mode Chokes are a type of electrical device used to protect circuits against electrical interference. They are also used to reduce the level of noise on power lines and in power systems. The DR221-474AE is a common type of Common Mode Choke used for applications in industrial and high-reliability systems.The DR221-474AE is a shielded core Common Mode Choke that is designed to provide maximum noise suppression and protection for circuits that are sensitive to electrical interference. The device features an effective shielding around the coil core that helps to reduce the level of electromagnetic interference (EMI) and Radio Frequency Interference (RFI) coming into contact with it. This helps to reduce the overall levels of noise on the power line, as well as any unintended signals coming through the power line.The DR221-474AE is a ferrite core device, which means that it has a higher impedance than other permanent-magnet types of Common Mode Chokes. This allows for a more effective suppression of noise, as the higher impedance helps to reduce the level of electrical interference. The core of the DR221-474AE is made up of a ferrite material, which helps to dissipate the electricity and reduce the effect of electrical interference.The DR221-474AE is designed to provide a high level of protection from both EMI and RFI interference. The device has two separate channels, with each channel providing between 20 dB and 30 dB of interference impedance. This helps to protect sensitive circuits from any interference or noise entering the circuit. The DR221-474AE is made up of two separate coils that help to reduce the level of noise on the power lines.The DR221-474AE is designed for use in both industrial and high-reliability systems. It is a suitable device for high-end applications, where the power lines need to be highly-protected against interference. The device also has a low cost, making it an ideal choice for industrial and high-reliability systems.The DR221-474AE works by providing an effective level of shielding around the internal wires and circuits. This helps to reduce the level of EMI and RFI that can come into contact with the device. The device can also reduce the level of noise on the power line, as well as any unintended signals coming through the power line. This helps to improve the overall performance and reliability of the system.In conclusion, the DR221-474AE is a versatile and reliable device that provides an effective level of shielding and protection for sensitive circuits. The device is designed to reduce the level of EMI and RFI interference and to reduce the amount of noise on the power lines. The device is an ideal choice for industrial and high-reliability systems, as it provides a low cost and reliable solution for protecting sensitive circuits.
