Part Number: TCAN1043G-Q1

Hi Sir,

My customer is using TCAN1043GDRQ1, could you help to advise the recommended common mode choke part number?

Thank you.

    Hi User,

    Any common mode choke (CMC) with around 51uH at 100kHz and a large impedance at high, non-CAN frequencies (>10MHz) will do fine. Many CMCs also advertise as designed for CAN systems.

    Here is an app note that discusses some factors to considering when choosing a CMC. It includes a table of several devices that may be helpful to you. 

    Regards,
