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, these filters effectively suppress common mode noise without distorting high-speed signals. They offer a high coupling constant of 0.99, a small and low-profile design for high-density packaging, and a range of common mode impedance options from 30 to 2200 ohms to suit various noise levels and signal frequencies. These filters 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 USB 2.0/3.0 applications.
