Coilcraft’s surface-mount common-mode chokes include 16 sizes for power line circuits up to 10A, suppressing noise up to 100MHz with >40dB attenuation in some cases. Consumer electronics and industrial applications are foreseen. “All EMI chokes feature a low-profile, toroidal construction in a surface-mount, magnetically-shielded package with footprints as small as 13 x 13 mm,” said ...
