7427021

Overview

The Würth Elektronik 7427021 is a split-core ferrite ring designed for electromagnetic interference suppression. It utilizes 4W620 material and provides an impedance of 106 Ω at 100 MHz. The component features a 7.8 mm inner diameter with a single split design, allowing installation on existing cables without disconnection. Its physical dimensions are approximately 15.0 mm in length, 13.0 mm in width, and 10.0 mm in height.

Feature Summary

• Split core construction enables rapid installation on pre-assembled cable assemblies
• Utilizes 4W620 ferrite material for effective high-frequency noise attenuation
• Designed specifically for suppressing electromagnetic interference in data lines

Applications

• Suppression of electromagnetic interference in computer peripheral cables
• Noise reduction for terminal equipment data lines
• EMI mitigation in general electronic circuit cabling

Procurement Notes

Verify the specific impedance value at 100 MHz against system requirements to ensure adequate noise suppression performance. Confirm that the 7.8 mm inner diameter accommodates the target cable bundle size with appropriate clearance. Ensure compliance with REACH and RoHS directives if required by the end-product regulations.

Selection Notes

Select this component when retrofitting EMI suppression onto existing cables is necessary due to its split design. Choose based on the required impedance profile at the target noise frequency and the physical constraint of the cable diameter. Consider the 4W620 material properties for the specific frequency range of interference.
