Coilcraft has introduced a new series of common mode chokes to provide noise suppression on CAN (1 Mbps) or CAN FD (5 Mbps) data lines in automotive and industrial automation applications. The 1812CAN Series of 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. The 1812CAN Series can also be used for the FlexRay automotive bus system.
Measuring just 4.95 X 3.18 X 3.0 mm, the low-profile 1812CAN Series is offered with inductance values from 11 to 100 µH to filter a broad range of common mode noise frequencies with high attenuation. It offers up to 60% lower DCR than other CAN bus chokes, resulting in much lower losses on differential signal lines.
The 1812CAN Series chokes are qualified to AEC-Q200 Grade 1 standards (-40° to +125°C ambient), making them suitable for automotive and other harsh-environment applications. They are also RoHS-compliant and have silver-palladium-platinum-glass frit terminations with a maximum reflow temperature of 260°C.
