74272590

Overview

The Würth Elektronik 74272590 is a split flat ferrite core designed for EMI suppression in ribbon cable applications. It belongs to the WE-SFA series and features a 26-pole configuration suitable for flat connectors. The component provides an impedance of 194 Ohms at a test frequency of 100 MHz. Its physical dimensions are 34 mm in length, with a width of 2 mm. This solid-type core is engineered to attenuate electromagnetic interference on data lines.

Feature Summary

• Split design allows installation onto existing cables without disconnection
• Optimized for suppressing common mode noise on flat ribbon cables
• High impedance characteristic effective at 100 MHz frequencies

Applications

• EMI suppression for flat ribbon cables
• Noise reduction in data transmission lines
• Electromagnetic compatibility enhancement in electronic equipment

Procurement Notes

Verify the specific impedance value of 194 Ohms at 100 MHz against your system requirements. Confirm that the 26-pole geometry matches the target connector pitch and cable width. Ensure the split construction is compatible with the assembly process. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when dealing with multi-line flat cables requiring targeted high-frequency attenuation. The 194 Ohm impedance offers a balance between signal integrity preservation and noise suppression. Consider the physical constraints of the 34 mm length within the available chassis space. Evaluate the need for split versus solid cores based on maintenance accessibility.

Part Context

This part is part of the WE-SFA series from Würth Elektronik, which specializes in ferrite solutions for EMI mitigation.
