Through Hole EMI Filter Beads RID

RID Family – High-Performance Through-Hole EMI Filter Beads with Dual Aperture Cores Through-hole ferrite bead EMI filters are essential components for suppressing electromagnetic interference (EMI) in modern electronic systems. The RID family of double-aperture core EMI filter beads is engineered to provide superior noise attenuation across a broad frequency spectrum while maintaining compact form factors ideal for high-density PCB layouts. How It Works: Magnetic Loss Mechanism in Ferrite Bead EMI Filters When current flows through the through-hole EMI filter bead, the ferrite core generates a magnetic field that induces energy dissipation—especially at high-frequency signals. This frequency-dependent impedance characteristic allows these passive components to act like resistors within targeted bands, effectively attenuating unwanted electromagnetic noise without affecting DC or low-frequency signal integrity. Unlike capacitive or inductive filters, ferrite bead EMI solutions offer b…
