Wurth WE-CNSW SMD Series Common Mode Chokes
Wurth WE-CNSW common mode filters offer high common mode suppression at high frequency and the winding symmetry provides small influence on high speed signals. Offered with a range of rated currents and impedance values, suitable applications for these common mode filters include USB 2.0, Firewire, LVDS, LAN, high speed data lines and common mode noise sources.
Reflow soldering recommended
Common mode EMI noise suppressed at high frequencies
Common mode EMI noise suppressed at high frequencies

For these non-cancellable (NC), and non-returnable (NR) products, Terms and Conditions apply.
