Common Mode Filtering Toroid & Balun Cores

Laird Technologies Common Mode Toroid and Balun Cores suppress unintended signals on or being emitted from cables or wires by acting on the magnetic fields surrounding them. If the unintended signals are not addressed, they can interfere with electronics and/or cause a failure to meet government emissions standards or susceptibility regulations. The toroid and balun cores from Laird Technologies have 125, 850, 1700, or 5000 permeability ratings, a wide range of frequency options (low, mid, high, and broad), and various coating options (perylene or epoxy).
