Common mode chokes are increasingly becoming important components in the signal transmission process, particularly in electrical circuits, due to their ability to reduce electromagnetic interference (EMI). The B82745S6123N002 is a high-performance common mode choke designed for applications requiring a low level of EMI. The device’s inductive and capacitive filtering blocks help to suppress both differential and common mode interference from the power line, ensuring high signal quality. Additionally, the B82745S6123N002 offers excellent RF shielding and thermal performance, with a high impedance range of up to 30MHz.

The working principle of a common mode choke begins with signal modulation. When two opposite-facing electromagnets are used to move a ferromagnetic core within a coil of wire, a sinusoidal current induces a voltage across the coil, producing a sinusoidal signal. This signal is then electromagnetically coupled to an output coil, creating a secondary signal. This secondary signal is identical to the input signal, except that the phase is shifted by approximately 90 degrees, signifying a positive voltage on one side and a negative voltage on the other. This phase shift attenuates the common mode currents, thus enhancing the signal-to-noise ratio.

The B82745S6123N002 is designed specifically for use in single-phase AC/DC power supplies. It features a wide range of currents (from 5A to 30A) and can handle high-frequency noise with maximum efficiency. With a built-in air-gap structure, the device offers excellent EMI suppression across a wide range of frequencies as well as high thermal dissipation. This makes the B82745S6123N002 an ideal choice for applications that require reliable EMI filtering.

In addition to its high level of EMI suppression, the B82745S6123N002 also features a high saturation current rating of 63A, a differential inductance of 2mH, and a series resistance of 0.8 Ohms, all of which provide enhanced pressure ratings for high-current applications. This makes it suitable for use in applications requiring high power ratings, including high-speed motor drivers, high-voltage inverters, and voltage regulators.

The B82745S6123N002 also benefits from a number of additional features, including a low leakage inductance of 0.2mH, a high-temperature resistant coating, and a single-channel output with three separate outputs. This combination of features makes the B82745S6123N002 suitable for use in many different applications, including line-to-line protection, motor driver protection, and temperature control.

In summary, the B82745S6123N002 is a high-performance common mode choke designed for applications requiring low levels of EMI. Its wide range of current ratings and high-frequency filtering capabilities make it suitable for a variety of applications, such as line-to-line protection, motor driver protection, Power line conditioning and temperature control. Additionally, its built-in air-gap structure and high thermal dissipation ensure reliable and effective EMI filtering.
