ISOW1044: Ferrite bead reference

Part Number: ISOW1044


Tool/software:

Hello,

In the datasheet you are suggesting the usage of the BLM15EX331SN1 as ferrite beads.

We would prefer to use ferrite beads from Wurth Electronic due to specific project constraints.

The 742792037 seems to be having quite similar characteristics, do you confirm it would be adequate ?

Best regards,

Clément

  • Hi Clement,

    Thank you reaching out.

    This Ferrite Bead becomes capacitive >500MHz, so I would not recommend using this as it can lead to higher emissions in 600MHz-1GHz for which the BLM15EX331SN1 was used for suppressing emissions in 600MHz-1GHz as it exhibits highest inductive behavior in that region as shown below.
