A Closer Look: MagJack® ICM Ethernet Magnetics

Bel MagJack ICMs help land system designers deal with the challenging and unpredictable nature of EMI problems. MagJack Integrated Connector Modules integrate the magnetic components in the ethernet connector. This includes common mode chokes and isolation transformers that are carefully designed to address conducted and radiated common mode and differential mode noise and provide immunity against ESD, EFT, and surge events.

Bel MagJack ICMs are available for voltage mode and current mode architectures and are offered in single and dual row versions with up to 16 ports. The connector modules support transmission speeds up to 10 gigabits per second and POE applications up to 100 watts. Bel also offers extensive in-house engineering experience to assist customers with their design and testing to help meet IEEE 802.3 and EMC requirements.
