742700727

Overview

The Würth Elektronik 742700727 is a cylindrical solid ferrite core from the WE-SAFB series, designed for EMI suppression. It features an inner diameter of 4.20 mm and an outer diameter of 9.00 mm, with a length of 15.50 mm. The component utilizes 7W700 material to provide an impedance of 118 Ω at 100 MHz and 60 Ω at 25 MHz. It is classified as a free-hanging cable ferrite suitable for general electronic equipment applications.

Feature Summary

• Solid cylindrical design for direct cable sliding
• High impedance performance using 7W700 material
• Free-hanging installation type

Applications

• EMI suppression in general electronic equipment
• Cable noise filtering
• Signal integrity enhancement

Procurement Notes

Verify the specific impedance requirements against the datasheet curves for 7W700 material at target frequencies. Confirm that the cable diameter fits within the 4.20 mm inner dimension. Ensure compliance with RoHS3 and REACH regulations if required by your project specifications before finalizing procurement.

Selection Notes

Select this part when a compact, solid ferrite bead is needed for cables up to 4.2 mm in diameter. The 7W700 material offers high impedance in the VHF/UHF range. Consider the physical dimensions (9.00 mm OD, 15.50 mm length) for spatial constraints. This component is distinct from split-core types due to its solid construction.

Part Context

This component belongs to the WE-SAFB series, which focuses on small-size EMI suppression beads. The series provides various sizes and materials to address different cable diameters and frequency ranges. The 742700727 specifically addresses needs for moderate cable sizes requiring high attenuation at higher frequencies.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users should consult Würth Elektronik directly for equivalent alternatives or cross-reference based on strict impedance and dimensional matching.
