2) Use a gate ferrite bead
[FBI in Figure 1] to prevent the high-frequency noise from entering the driver and logic circuits.
There's also an adjustable ferrite bead
on the cable whose weight ensures the cable does not protrude out of your cabinet when connected.
The ferrite bead
is the simplest type of the filter: it is characterized by low cost and significant attenuation of short electromagnetic pulses (similar to high-frequency signal) in conductors connected to electronic apparatus.
3) was designed close to CISPR 25 requirements, with exception that inductance was formed by special low frequency ferrite bead
LFB095051 from Laird, mounted on incoming wires.
Adding a ferrite bead
to the fixture wire can raise fixture inductance.
The inductor packaging options are similar: a ferrite bead
around the connector pin, or a ferrite slab which all the pins pass through.

, solder mountable," Murata Manufacturing, News Release, May 10, 2016.
The BLM 15H Ferrite Bead
Series provides EMI suppression into the gigahertz frequency range in an 0402 package size.
Especially for PDAs and notebook computers, Murata offers the BLA2A Series of four-circuit surface-mount ferrite bead
