Common Mode Filtering Toroid & Balun Cores

Laird 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 offer permeability ratings of 125, 850, 1700, or 5000, along with a wide range of frequency options (low, mid, high, and broad) and various coating options (perylene or epoxy).
