EMI ferrite disks and plates

Wherever EMI and active antennas disrupt the circuit board after the soldering process, Laird Steward ferrite disks and plates offer a simple, cost-effective solution.

 The ferrite disks and plates can be utilised either as inductively coupled components or, as EMI shields on PCBs. The inductive coupling occurs when the ferrite affects the conducted waveform leaving the active component. The rise time of the waveform is effectively slowed by the ferrite. The overshoot and associated ringing are attenuated.

On PCBs, they can be placed directly on the EMI source, absorbing the radiated emissions at their core. This can help streamline your design and reduce overall material cost with maximum efficiency.
