DESCRIPTION
The TOKO NT2012 is a wirewound miniature
common mode filter specifically designed to
eliminate common mode noise in USB 2.0,
IEEE1394, LVDS, DVI, and HDMI applications.
A dual winding configuration in a tight form
factor provides exceptional EMI reduction in
space-constrained environments.
