TCAN1043A-Q1: Common Mode Choke value for CAN-FD

Lakshmanan Rajarathinam

Hi there,

I am using the TCAN1043A-Q1 in our IVI project, and the CAN FD requirement is to support data rates up to 5 Mbps. We are planning to use a common-mode choke on the CAN lines; however, I am unsure about the appropriate inductance value.

Could you please advise whether 51 µH or 100 µH would be more suitable for reliable operation at 5 Mbps, or suggest a recommended value?

Thank you for your support.
