WIREWOUND COMMON MODE FILTER
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.
