742730022

Overview

The Würth Elektronik 742730022 is a four-way multiline EMI suppression ferrite bead belonging to the WE-MLS series. It functions as a high-impedance common-mode inductor utilizing 2x2 windings created through PCB line connections. The component provides an impedance of 208 ohms at 25 MHz and 248 ohms at higher frequencies. Designed for surface-mount applications, it effectively suppresses electromagnetic interference across multiple signal lines within compact electronic assemblies.

Feature Summary

• Four-channel multiline configuration for simultaneous multi-line noise suppression
• High-impedance common-mode inductance characteristics
• Integrated 2x2 winding structure formed via PCB line connection technology

Applications

• Multi-line data interface protection
• Common-mode noise suppression in dense PCB layouts
• EMI filtering for high-speed digital signal lines

Procurement Notes

Verify the specific impedance tolerance and frequency response curve against the official datasheet before integration. Confirm that the PCB land pattern matches the manufacturer's recommended footprint dimensions. Ensure the selected package variant aligns with the assembly process requirements and thermal management constraints of the final design.

Selection Notes

Select this component when designing circuits requiring simultaneous suppression on four parallel lines without occupying excessive board area. The integrated PCB line connection design simplifies routing compared to discrete components. Evaluate the 208 ohm impedance value at 25 MHz to ensure adequate attenuation for the target noise spectrum while maintaining signal integrity for the connected interfaces.
