7427256

Overview

The Würth Elektronik 7427256 is a split flat ferrite core designed for electromagnetic interference (EMI) suppression. It belongs to the WE-SFA series and features an impedance of 175 ohms at 100 MHz. The component measures 83.4 mm in length, 2.4 mm in width, and 1.9 mm in height. It accommodates up to 64 conductors within its opening. The unit is RoHS compliant and manufactured in Taiwan.

Feature Summary

• Split design allows installation on existing cables without disconnection
• Provides EMI noise suppression for high-density cable bundles
• Accommodates up to 64 individual conductors simultaneously

Applications

• Suppression of electromagnetic interference in multi-conductor cables
• Noise filtering for data transmission lines
• EMI mitigation in industrial equipment wiring harnesses

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet before integration. Confirm that the target cable bundle fits within the specified conductor capacity and dimensional constraints. Ensure compliance with relevant environmental standards required by the final assembly specifications.

Selection Notes

Select this component when managing dense cable assemblies requiring simultaneous noise reduction. The split architecture facilitates retrofitting onto installed wiring. Evaluate the 175-ohm impedance characteristic against the frequency spectrum of the targeted interference signals to ensure effective attenuation performance.

Part Context

This part is categorized as a ferrite cable core within the WE-SFA product line. It serves as a passive component for signal integrity enhancement. The device functions by absorbing high-frequency noise energy, converting it into negligible heat. It is distinct from solid ring cores due to its snap-open mechanism.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation.
