user021864

Part Number: AMC1100

Hi,

My customer is having issue for the AMC1100, it will have issue of 10MHz to 11MHz EMI comes from the device, may I ask how to filter it?

Great thanks for your help.

Please refer to the capture from the schematic, and let me know if there are further information needed.

This is a DC motor with 96V DC input.

Thanks a lot.

Hi Gary,

Can you provide more detail on the noise you've seen? Also, please confirm that the schematic is correct - with the setup as it is shown, it looks like you have ~48V on the AMC1100 input.

Hi user021864,

I would give common mode filtering a try, as discussed in this thread:
