Common Mode Chokes (CMCs) have become increasingly popular in consumer products due to their great potential for eliminating electromagnetic interference (EMI) in radio frequency and high-speed communication systems. CMCs consist of an inductor with two windings (primary and secondary) around core material, which is used to suppress common mode interference (CMIs). The B82615B2352M1 is a common mode choke specifically designed for EMI reduction in Ethernet and radio frequency applications. This parts works by providing a low-resistance path to CMIs and, at the same time, blocking them from interfering with signals passing through the winding.

The B82615B2352M1 has an inductance range from 0.1µH to 0.3µH and an impedance that changes with frequency. It is designated as a “Power Over LAN” (PoL) choke because it has the ability to withstand high currents without excessive losses. It also has high saturation current ratings that enable the device to handle large bursts of energy.

The B82615B2352M1 is generally employed in PoE and PoE+ applications, where two or more power lines share a single cable. It is designed, among other things, to suppress any common mode noise that may interfere with the power transmission. The maximum current rating of the B82615B2352M1 is 2.5A, which is sufficient to handle the power demands of most PoE and PoE+ applications.

The B82615B2352M1 also works well in radio frequency (RF) applications. It operates in the range of 0.02 to 10MHz, which is ideal for suppressing noise in both HF and VHF frequencies. The device also provides a low-resistance path to CMIs, enabling it to effectively block RF noise from interfering with signals.

The working principle of the B82615B2352M1 is based on Faraday’s law of induction. This law states that an inductor will store magnetic energy when current passes through it. The B82615B2352M1 utilizes this property in order to suppress common mode noise. The current in the primary and secondary windings create a “virtual ground” in the core material, which prevents the noise from entering the signal path.

The B82615B2352M1 is an efficient and cost-effective way to reduce EMI in Ethernet and radio frequency applications. It is particularly suited for PoE and PoE+ networks, as it has a high current rating and low saturation current ratings. The device’s Faraday-based working principle also ensures effective suppression of CMIs. Overall, the B82615B2352M1 is an ideal solution for EMI reduction in a wide variety of applications.
