Coilcraft 1812CAN Series common-mode chokes

Coilcraft’s 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. The series can also be used for the FlexRay automotive bus system.

Measuring 4.95 x 3.18 x 3 mm, the low-profile 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, according to the company, resulting in lower losses on differential signal lines.

The series is qualified to AEC-Q200 Grade 1 standards (-40 to +125°C ambient), making it suitable for automotive and other harsh environment applications. It features RoHS-compliant, silver-palladium-platinum-glass frit terminations and offers a maximum reflow temperature of 260°C.
