74272571

Overview

The Würth Elektronik 74272571 is a split flat ferrite core designed for EMI suppression in WE-SFA series applications. It provides an impedance of 170 Ohms at the specified test frequency and accommodates 20 poles. The component features a compact form factor with dimensions of 26.6 mm in length, 1.6 mm in height, and a width suitable for flat ribbon cables. It is constructed from manganese-zinc material and includes a metal spring clip for secure mounting on cables.

Feature Summary

• Split design allows installation onto existing cables without disconnection
• Includes integrated metal spring clip for secure mechanical attachment
• Optimized for suppressing electromagnetic interference in flat ribbon cable configurations

Applications

• EMI suppression for flat ribbon cables
• Signal integrity enhancement in data transmission lines
• Noise reduction in multi-conductor cable assemblies

Procurement Notes

Verify the specific impedance value and pole count against the official datasheet before integration. Confirm that the included spring clip meets the mechanical retention requirements of the target assembly. Ensure compatibility with the flat cable thickness to guarantee proper closure of the split core.

Selection Notes

Select this component when managing high-density flat ribbon cables requiring effective common-mode noise attenuation. The split design facilitates retrofitting into existing harnesses. Verify that the 170 Ohm impedance profile aligns with the noise frequencies present in the application environment.

Part Context

This part belongs to the WE-SFA series of flat ferrite cores from Würth Elektronik. These components are engineered specifically for suppressing electromagnetic interference in flat cable applications. The series offers various impedance levels and pole counts to suit different signal line densities and noise profiles.

Replacement Considerations

Check for direct substitutes within the WE-SFA series that match the 20-pole requirement and similar impedance characteristics. Ensure any replacement maintains the split-core design with an integrated mounting clip for equivalent ease of installation.
