Common Mode Chokes: B82721A2501N001 Application Field and Working PrincipleCommon mode chokes, sometimes known as broadband chokes, Differential Mode Chokes (DMC), or line filters, are integral components used in many energy, residential, industrial, and resonance-based applications. This kind of component is designed to reduce frequency disturbances that can cause electrical overvoltage, preclude interference with other appliances, and reduce emissions. The use of Common Mode Chokes (CMC) is essential for maintaining the integrity and stability of the system. The specific type of CMC being reviewed is named B82721A2501N001. Like all CMC, it has distinct application fields and functionality.The B82721A2501N001 is part of the EMC F50-series, manufactured by Murata Power Solutions. This type of CMC is designed for the highest degree of efficiency and is rated for currents up to 10A. Its self-inductance was calculated and found to be lower under the same operating conditions than most other common mode chokes, allowing for a higher current and voltage range than most competitors. It is particularly robust against any sudden changes in its environment, as well as any extreme temperatures or humidity. Specifically, the B82721A2501N001 CMC has a rated dielectric strength of 1820 volts, making it a great fit for heavy industrial applications where high voltage, power surges, and transformers must be accounted for.The working principle of a CMC is relatively simple. To start, they are composed of electromagnetic coils wound around a ferrite core. This design creates two separate circuits inside the choke, which prevents the flow of interference current. By blocking high-frequency alternating current, CMCs reduce the amount of EMC interference that can affect neighboring electronics. In the case of the B82721A2501N001, Murata has included additional features, such as low-profile connector designed to provide a perfect match with other power components, and self-bonding wires which help to further reduce ongoing EMC interference.On the technical side, the B82721A2501N001 is a 5-terminal vertical pin IC package, measuring roughly 11.3mm in length and 8.4mm in width. It has a nominal inductance of 52 µH and a maximum DC blocking voltage of 1820 volts. Operating temperature requirements for this CMC are between −40 degrees C and +125 degrees C. In power applications, its recommended for a 24VDC voltage input and is UL recognized as a VDE ENEC approved component. Although more expensive than some other CMC on the market, this model proves to be a great investment and is highly recommended for high-end industrial applications.To summarize, the B82721A2501N001 is a type of Common Mode Choke manufactured by Murata Power Solutions. It\'s designed for maximum efficiency and is intended for applications where high voltage, power surges, and transformers are present. It has a low self-inductance rating, allowing it to handle larger currents and higher voltages than most other CMC on the market. In addition, its 5-terminal vertical pin IC package design features a low-profile connector to accommodate nearby power applications and self-bonding wires to reduce ongoing EMC interference. The B82721A2501N001 CMC is UL recognized and VDE ENEC approved, making it a great choice for heavy industrial applications.
