Model PMDX-USB-Choke


picture of PMDX-LineFilter-20D_400.jpg

Ferrite Ring common-mode choke for use with USB cables

The PMDX-USB-Choke helps prevent electrical noise from corrupting USB communications

  • Ferrite ring allows you to loop the USB cable through it several times
  • Acts as a common mode filter to decrease the amount of high edge rate common mode noise traveling along the cable
  • Recommended for use near the host computer's USB port because many computers lack an internal common mode filter
  • PMDX SmartBOB devices have an internal common mode filter, but you can use this one at the device end for devices that do not have a filter
  • Center hole is 3/4 inches in diameter to allow USB plugs to pass through it
  • The ring should be placed as near the USB port or USB device as possible

The PMDX-USB-Choke is priced at $3.00 each.
