Product Overview
The SMW-B Series Wire-wound Common Mode Filter is a powerful component designed to solve EMI problems in high-speed differential signal transmission lines such as USB, IEEE1394, and LVDS. Utilizing a composite co-fired material, it effectively suppresses common mode noise without distorting high-speed signals. With a high coupling constant of 0.99, small size, and low profile, these filters enable higher density packaging. A variety of common mode impedance options are available (67 to 220 ohm) to suit different noise levels and signal frequencies. They are RoHS compliant and ideal for common mode noise suppression in high-speed and high-density digital equipment, including PCs, peripheral equipment, and small digital AV equipment for USB2.0/3.0 applications.
