7427220

Overview

The Würth Elektronik 7427220 is a solid flat ferrite core designed for electromagnetic interference suppression. It belongs to the WE-FLAT series and utilizes 4W620 material composition. The component provides an impedance of 90 Ω at 100 MHz. Its internal dimensions are 28.00 mm width by 1.30 mm height, while external dimensions measure 33.50 mm width by 6.50 mm height. The core length is 20.00 mm. It supports free-hanging installation and complies with RoHS standards.

Feature Summary

• Solid flat design optimized for flat cables
• High impedance performance at 100 MHz
• Free-hanging installation capability

Applications

• Flat cable EMI suppression
• Digital equipment noise reduction
• Cable and wiring filtering

Procurement Notes

Verify the specific part number suffix when ordering, as variations exist within the WE-FLAT family. Confirm that the solid core configuration matches the application requirements rather than hinged or snap-fit alternatives. Check current availability status through authorized distributors to ensure supply continuity for production schedules.

Selection Notes

Select this component when flat cable geometry requires integrated magnetic suppression without additional mounting hardware. The 90 Ω impedance at 100 MHz suits high-frequency noise attenuation. Ensure the internal aperture accommodates the target cable bundle diameter. Consider the physical footprint constraints against available board or chassis space.

Part Context

This part is part of the WE-FLAT product line from Würth Elektronik, specialized for flat cable applications. It complements other EMI components like the 742722 Design Kit, which includes various ferrite cores for development purposes. The solid construction distinguishes it from hinged or snap-on variants in the manufacturer's portfolio.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model.
