Common Mode Chokes, of which B82505WA6 is a member, are components used to suppress Common Mode Interference (CMI) within a system. The B82505WA6 is very effective against forms of CMI with frequencies up to 30 MHz, such as EMI, RFI, and ESD. It is also notable for its low DC power loss, meaning it can be used effectively for low-voltage applications.

The main working principle of the B82505WA6 is providing high impedance to electrically interfere signals of differing frequencies, which attempts to maintain the power flow of the electronic transmit line. It is used for the differential mode of power transmission in electromagnetic equipment, with much better than expected results. The B82505WA6 is commonly used for suppressing CMI in data links, power lines, and RF communication systems.

The B82505WA6 is comprised of a ferrite core and two sets of windings. The ferrite core provides a permittivity capable of providing high impedance while allowing signals of various frequencies to pass through. This core also gives the B82505WA6 a high magnetic permeability with an insulation covering to protect the windings. The windings are in turn laid around the ferrite core and are formed by a combination of internal and external isolation of each of the windings. The internal insulation serves to provide electrical separation while the external insulation provides mechanical support and vibration dampening.

To use the B82505WA6 correctly, the choke must have the windings of the two coils connected in the same direction and the coils must both be properly placed onto the ferrite core. Additionally, parameters such as the turns, number of layers, and core diameter should be optimized and tuned for the system in which it is to be applied according to their individual requirements.

The B82505WA6 is a great choice for designers looking for a common mode choke that has great reliability, low DC power loss, and adjustable performance. The B82505WA6’s wide frequency range and easy-to-handle installation make it an economical choice for suppressing EMI, RFI, and ESD in systems needing up to 30 MHz of CMI protection.
