74272591

Overview

The Würth Elektronik part number 74272591 is a split flat ferrite core designed for RFI suppression. It accommodates up to 40 wires with an internal width of 2 mm. The component exhibits an impedance of 180 Ohms at 100 MHz and utilizes 4W620 material. External dimensions are 63 mm in width, 28.5 mm in height, and 13 mm in depth. It features an openable design for easy installation on existing cables.

Feature Summary

• Split flat design allows installation on pre-assembled ribbon cables without disconnection
• Capable of accommodating up to 40 individual conductors within the core aperture
• Utilizes 4W620 ferrite material optimized for high-frequency noise attenuation

Applications

• RFI suppression for multi-conductor ribbon cables
• Noise reduction in computer data transmission lines
• Electromagnetic interference mitigation in power cable assemblies

Procurement Notes

Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure authenticity. Confirm that the required impedance characteristics align with the target frequency spectrum of the application. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when dealing with flat ribbon cables containing multiple conductors requiring simultaneous noise suppression. Ensure the cable bundle fits within the 2 mm internal width constraint. Evaluate the 180 Ohm impedance value at 100 MHz against the specific noise frequencies present in the system to confirm effective attenuation performance.

Part Context

This component belongs to the WE-SFA series of split flat ferrite cores from Würth Elektronik. These cores are engineered specifically for suppressing radio frequency interference on flat cabling structures. The series provides a practical solution for retrofitting noise suppression onto existing harnesses without modifying the cable termination or connector interfaces.
