Wirewound Ferrite Beads SMB

Ferrtx SMB Series Wire Wound Ferrite Beads are designed for effective high-frequency noise suppression on signal and power lines, with particular suitability for audio signal paths and sensitive electronic circuits.

This page focuses exclusively on the SMB product family, independently separated from the legacy Wirewound Ferrite Bead range to provide clearer selection guidance and application-specific performance.

What Are Wire Wound Ferrite Beads?

Wire Wound Ferrite Beads combine a Ferrite Core with precision copper windings to enhance impedance characteristics across a broad frequency spectrum. Compared with conventional ferrite beads, the wirewound structure provides:

• Higher impedance stability

• Improved current handling

• More controlled inductance behavior

These advantages make wirewound beads especially effective in low-noise and audio-related applications where signal integrity is critical.

SMB Series Ferrite Beads for Audio Applications

The SMB Series ferrite beads for audio are optimized to suppress high-frequency interference without degrading low-frequency audio signals. They are widely used to eliminate:

• Switching noise from power supplies

• RF interference coupled into audio lines

• Digital noise affecting analog audio paths

In mixed-signal designs, SMB beads are often used together with ferrite bead inductor or Power Line Common Mode Choke components as part of a layered EMI Filter strategy.
