7427804

Overview

The Würth Elektronik 7427804 is a solid flat ferrite cable core from the WE-FLAT series, designed for electromagnetic interference suppression. It features an impedance of 127 Ohms at a test frequency of 100 MHz and utilizes 4W620 core material. The component has external dimensions of 16 mm in length, 5 mm in height, and 2 mm in width, with an internal slot measuring 11.5 mm by 0.5 mm to accommodate flat ribbon cables. It operates within a temperature range of -25°C to +125°C and complies with RoHS standards.

Feature Summary

• Solid construction provides stable shielding for flat ribbon cables without requiring assembly tools.
• High impedance characteristics effectively attenuate high-frequency noise on digital data lines.
• Compact physical profile allows integration into space-constrained electronic assemblies.

Applications

• Electromagnetic interference suppression on flat ribbon cables
• Noise filtering in general electronic equipment
• Shielding for digital device signal lines

Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure compatibility with design requirements. Confirm that the 127 Ohm impedance at 100 MHz meets the target noise suppression specifications. Check for RoHS compliance status as indicated in current datasheets. Ensure the internal slot dimensions are sufficient for the intended cable thickness.

Selection Notes

Select this component when dealing with flat ribbon cables rather than round wires. The 127 Ohm impedance value is suitable for general-purpose EMI suppression in digital circuits. Consider the operating temperature range of -25°C to +125°C for environmental suitability. The solid design eliminates the need for opening and closing mechanisms found in split cores.

Part Context

This component belongs to the WE-FLAT series of ferrite cable cores manufactured by Würth Elektronik. These components are specifically engineered for use in general electronic equipment to mitigate electromagnetic interference. The series offers various impedance values and dimensions to suit different cable types and noise profiles.

Replacement Considerations

Consult official Wurth Elektronik documentation for verified substitute part numbers within the WE-FLAT series or other compatible families. Ensure any replacement maintains the required 127 Ohm impedance at 100 MHz and fits the 11.5 mm x 0.5 mm internal slot dimensions.
