Laird Common-Mode Choke

Laird chokes exhibit superior impedance performance well into the 100 kHz range and below. The internal construction of these chokes are of the wound toroidal fashion. They use a large number of cable pairs twisted or non-twisted. This configuration reduces RFI and cross talk associated with balanced wires found in most common chokes. With typical peak impedances ranging from 2 kohms to 13 kohms in the frequency ranges of 18 to 80 MHz these parts are perfect for suppressing noisy common mode signal lines.
