New low-profile Common mode chokes from Coilcraft offer noise suppression in CAN or CAN FD applications

common mode chokesCoilcraft’s new 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 1812CAN Series can also be used for the FlexRay automotive bus system.

Key features of the 1812CAN Series

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 claims to offer up to 60% lower DCR than other CAN bus chokes, resulting in much lower losses on differential signal lines.

The 1812CAN 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.

Availability

Parts are available from stock and can be ordered on-line at buy.coilcraft.com or by calling a local Coilcraft sales office.
