ISOW1412: Ferrite beads on pin1, 9, and 10

Part Number: ISOW1412
Other Parts Discussed in Thread: ISOW7741

Hello team,

Do we have recommended value for ferrite beads on pin1, 9, and 10?

Best regards,


  • Hi Sakai-san,

    Thank you for reaching out.

    You can use the same ferrite beads (BLM15EX331SN1) that are recommended in the datasheet for VISOOUT, please refer to Layout Guidelines section for the part number and other details. You can also refer to the below application note that details the reasons for using these components and specifies how to choose the ferrite beads. The document primarily refers to ISOW7741 but is equally applicable for ISOW1412. Thanks.
