7427211

Overview

The Würth Elektronik part number 7427211 is a WE-FLAT flat ferrite core designed for electromagnetic interference suppression. It features a round configuration with 21 poles and an internal width of 28mm. The component exhibits an impedance of 55 Ohms at 100MHz, utilizing 4W620 material composition. This snap-on type core facilitates rapid installation on cables without requiring disconnection.

Feature Summary

• Snap-on design enables quick installation on existing cable assemblies
• Flat geometry accommodates specific cable bundling requirements
• Integrated pole structure enhances high-frequency noise attenuation

Applications

• General electronic equipment EMI suppression
• Cable noise filtering in industrial systems
• Power line interference reduction

Procurement Notes

Verify the exact physical dimensions and impedance specifications against the official datasheet before integration. Confirm material grade compatibility with operating temperature ranges. Ensure the cable diameter fits within the core aperture to maintain effective magnetic coupling and suppression performance.

Selection Notes

Select this component when a flat-profile ferrite core is required for space-constrained applications. The 21-pole design offers enhanced performance compared to standard single-loop cores. Consider the 55 Ohm impedance at 100MHz for targeted frequency range suppression needs.

Part Context

This part belongs to the WE-FLAT series from Würth Elektronik, specifically engineered for flat or bundled cable applications. It differs from circular snap-on rings by its specialized cross-section, optimizing fit for rectangular or grouped wire harnesses while maintaining high-frequency noise suppression capabilities.

Replacement Considerations
