"A ferrite bead is a passive electric component used to suppress high frequency noise in electronic circuits. It is a specific type of electronic choke. Ferrite beads employ the dissipation of high frequency currents in a ferrite ceramic to build high frequency noise suppression devices. Ferrite beads may also be called blocks, cores, rings, EMI filters, or chokes"

There are at least 3 different types of those on N64 controllers.
- shrink tubed
- TDK branded
- Nintendo branded

Every controller in Germany and probably the rest of Europe has them.
