742750421

Overview

The Würth Elektronik part number 742750421 is a WE-UKW EMI Suppression component classified as a 6-Hole Ferrite Bead. It provides an impedance of 230 Ohms and supports a current rating (IR) of 3 Amperes. This multi-hole design allows for the simultaneous suppression of multiple conductors within a single assembly, offering a compact solution for high-density cable management in electronic systems.

Feature Summary

• Six-hole configuration enables simultaneous suppression of multiple cables or wires
• Designed for effective electromagnetic interference (EMI) attenuation
• Supports a continuous current rating of 3 Amperes

Applications

• Multi-conductor cable harnesses requiring common-mode noise reduction
• High-density data transmission lines
• Power supply input/output filtering in compact enclosures

Procurement Notes

Verify the specific datasheet version to confirm mechanical dimensions and material composition. Ensure the selected variant meets the required current handling and impedance specifications for the target frequency range. Cross-reference with official Wurth Elektronik documentation to validate compliance with relevant environmental standards before integration into the final design.

Selection Notes

Select this component when space constraints prevent the use of individual ferrite beads for each conductor. The six-hole design is optimal for bundling multiple signal or power lines together. Evaluate the total cross-sectional area of the cables to ensure they fit within the apertures without excessive force that could damage the ferrite material or the cable insulation.

Part Context

This component belongs to the WE-UKW series from Würth Elektronik, which specializes in ultra-wideband EMI suppression solutions. The series offers various configurations to address noise issues across a broad frequency spectrum. The 6-Hole variant specifically targets applications where multiple lines require filtering in a confined physical space.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific 6-hole configuration. Alternative solutions may require redesigning the cable layout to accommodate separate ferrite beads or different multi-hole geometries from other manufacturers.
