Kawai
Guru 19785 points

Hi Team,

Our customer will transfer power using STP cable. I believe the schematic would be the one in the attached file.

Could you please help us on the following questions ?

Q1) Could you please tell me the requirements for L3 ?

Q2) We cannot find the datasheet of Coilcraft KA4909-AL, is it possible to provide us the specification of this inductor ?

Best Regards,
Kawai

    Hi Team,

    Could anybody support us on the inductor requirement and the datasheet for CoilCraft KA4909-AL ?

    Our customer is having trouble designing their system. We appreciate it if we could have the information by tomorrow so that customer could meet their design schedule.

    For the inductor requirements, I believe that application note does not mention about KA4909-AL. Is the key specification saturation current and 1kohm at over 100MHz ?

    Please give us your advice.
    Your quick response would be greatly appreciated.

    Best Regards,
    Kawai
