Through Hole EMI Filter Beads RWW

Ferrtx Through Hole EMI Filter Beads are designed to provide effective suppression of high-frequency electromagnetic interference in power and signal lines. Using optimized Emi Filter Ferrite materials, these beads offer stable impedance characteristics across a wide frequency range, making them ideal for industrial and electronic equipment requiring robust EMI control.

This page focuses specifically on the RWW series, which has been separated from the legacy product structure to meet targeted application and performance requirements.

EMI Filter Ferrite Beads – How They Work

An EMI filter ferrite bead functions by converting high-frequency noise energy into heat through magnetic losses, while allowing low-frequency signals and DC current to pass with minimal attenuation.

Compared with traditional ferrite bead inductor solutions, through hole ferrite bead filters provide:

• Higher current handling capability

• Improved mechanical stability

• Reliable performance in harsh environments

These characteristics make them suitable for both signal and power line noise suppression.
