7427213

Overview

The Würth Elektronik part number 7427213 is a solid flat ferrite cable core from the WE-FLAT series, designed for common-mode interference suppression on ribbon cables. Constructed from 4 W 620 material, it provides an impedance of 67 Ohms at 25 MHz. The component features internal dimensions of 34.8 mm in length and 1.3 mm in height, with external dimensions of 40 mm width, 12 mm depth, and 6.5 mm height. It supports a maximum of 26 wires within its aperture.

Feature Summary

• Solid construction specifically engineered for easy installation over flat ribbon cables
• Utilizes 4 W 620 ferrite material to attenuate common-mode noise
• Provides defined impedance characteristics for signal integrity enhancement

Applications

• Filtering common-mode interferences on computer data ribbon cables
• EMI suppression on power supply cables
• Noise reduction on circuit board interconnects

Procurement Notes

Verify the specific manufacturer part number 7427213 against official Wurth Elektronik documentation to ensure correct material grade and dimensional tolerances. Confirm RoHS and REACH compliance status through current datasheets. Check for any product change notifications or obsolescence notices prior to finalizing procurement decisions.

Selection Notes

Select this component when filtering flat ribbon cables rather than round wires due to its specific internal cross-section. Ensure the target cable bundle fits within the 1.3 mm internal height constraint. Verify that the 67 Ohm impedance at 25 MHz aligns with the required noise frequency spectrum for the application.

Part Context

This component belongs to the WE-FLAT series of ferrite cores, distinct from snap-ring or split-core types. It is manufactured by Würth Elektronik, a provider of electronic components and systems. The WE-FLAT line focuses on solid cores optimized for flat cable geometries, offering a permanent solution for EMI suppression without the need for locking mechanisms.
