Common Mode Chokes are widely used in electrical systems to suppress the transmission of interference. They can be used in both AC and DC circuits to reduce EMI. B82721A2402N020 is an excellent example of a Common Mode Choke designed to provide a high level of noise suppression, in particular differential-mode current and single-ended noises. It is constructed with two ferrite cores wound bifilarly and offers high attenuation of unwanted noise, up to 50dB, in a range of 1MHz to 300MHz.

The core of a Common Mode Choke, like the B82721A2402N020, provides a toroidal inductor that is wound with two bi-filarly wound windings configured for the maximum common-mode attenuation. The two windings are connected internally. When voltage is applied to the windings, a magnetic field is formed, which helps to inductively oppose the noise caused by interference. Common Mode Chokes are commonly used in alternating current circuits where the component’s inductance reduces the noise in the circuit.

The B82721A2402N020 is designed for use in high voltage direct current as well as in switched mode power supplies. The other great advantage of this Common Mode Choke is that it can also be used to reduce EMI in both balanced and unbalanced circuits. The choke reduces RFI and EMI noise that would otherwise affect the performance of the circuit.

The B82721A2402N020 is designed in such a way that it allows differential-mode currents to pass while blocking the common-mode currents. The differential-mode current is the primary current that directly supplies the load and only passes through one winding of the Common Mode Choke. The common-mode component is the current that flows in the opposite direction (return path) and is blocked by the Common Mode Choke. This helps to reduce common mode interference.

The choke also helps to reduce single-ended interference. Single-ended interference is the electrical noise caused by a single end of a power source. It occurs when one of the power source lines has noise on it, which can affect the entire circuit if not blocked. Common Mode Chokes, like the B82721A2402N020, are ideal for this purpose, as they can block single-ended noise without affecting the load. This is done by creating an inductive link between the two coils, which blocks the single-ended noise from entering the circuit.

The B82721A2402N020 is an excellent example of a Common Mode Choke that provides a reliable and high level of noise suppression for a wide variety of applications. With high attenuation of unwanted noise in the frequency range of 1MHz to 300MHz, it is perfectly suited for applications where EMI requires superior noise suppression. The high impedance and low DC resistance of this product make it ideal for both high and low voltage direct current as well as switched mode power supplies.
