Low-profile common mode choke suppresses noise

October 31, 2018  Stephen Law

COILCRAFT 1812CAN Series common mode chokes provide noise suppression on CAN (1 Mbps) or CAN FD (5 Mbps) data lines in automotive and industrial automation applications. CAN Common Mode Chokes are the most commonly-used filter component to attenuate common mode noise at the CAN bus (Controller Area Network) transceiver’s output. Low-profile devices measure 4.95 X 3.18 X 3.0mm and provide inductance values from 11 to 100µH to filter a broad range of common mode noise frequencies with high attenuation. Devices offer up to 60% lower DCR than other CAN bus chokes, resulting in much lower losses on differential signal lines.
