WE-CNSW High Frequency Common-Mode Line Filters

Würth Elektronik WE-CNSW High-Frequency Common-Mode Line Filters are SMD inductors that offer high common-mode suppression at high frequencies. Available in 0603, 0805, 1205, 1210, and 1812 case sizes, the WE-CNSW filters have a small influence on high-speed signals through winding symmetry and operate within a temperature range of -40°C to +85°C, +105°C, or +125°C. Applications for the Würth Elektronik WE-CNSW High-Frequency Common-Mode Line Filters are USB 2.0, USB 3.0, HDMI, LVDS, high-speed data lines, IEEE 1394 (FireWire), LAN, and common-mode noise sources.
