7427808

Overview

The Würth Elektronik 7427808 is a solid flat ferrite cable core designed for flexible printed circuit boards. It belongs to the WE-FLAT series and utilizes 4W810 ferrite material. The component provides an impedance of 20 Ohms at 100 MHz. Its internal dimensions are 5 mm in length, 3 mm in width, and 0.7 mm in height. External dimensions measure 7 mm in length, 3 mm in width, and 2.3 mm in height.

Feature Summary

• Solid construction suitable for flexible printed circuit board applications
• Designed specifically for flat ribbon cables
• Utilizes 4W810 ferrite material for EMI suppression

Applications

• Flexible Printed Circuit Boards
• Flat Ribbon Cables
• Digital Equipment Signal Lines

Procurement Notes

Verify the specific manufacturer part number 7427808 against official Wurth Elektronik datasheets to ensure correct impedance and dimensional specifications. Confirm RoHS compliance status through current certification documents before integration into designs requiring restricted substance limitations.

Selection Notes

Select this component when suppressing electromagnetic interference on flat ribbon cables within flexible PCB assemblies. The 20 Ohm impedance at 100 MHz suits general digital signal lines. Ensure physical clearance accommodates the 7 mm external length and 2.3 mm height constraints during layout planning.

Part Context

This component is part of the WE-FLAT series from Würth Elektronik, specialized for flat cable applications. It differs from split cores by being a solid unit, requiring cable insertion prior to assembly. The series targets high-density electronics where space efficiency and reliable EMI performance are critical for signal integrity.

Replacement Considerations

Check Wurth Elektronik documentation for direct substitutes within the WE-FLAT series with matching 20 Ohm impedance and compatible internal dimensions. Verify material composition equivalence if operating frequency ranges differ significantly from standard digital signals.
