7427050

Overview

The Würth Elektronik part number 7427050 is a WE-RIB series ferrite cable core designed for electromagnetic interference suppression. It features a multi-aperture design with dimensions of 1 mm, 5 mm, and 5 mm. The component exhibits an impedance of 146 Ohms at 100 MHz for single wire configurations and 134 Ohms at 100 MHz for double wire setups. This split-core ferrite allows for installation on existing cables without disconnection.

Feature Summary

• Multi-aperture geometry facilitates rapid installation on bundled or individual conductors
• Split-core construction enables retrofitting onto live wiring harnesses
• Optimized impedance characteristics provide effective noise attenuation in high-frequency ranges

Applications

• Data lines for telecommunications equipment
• Suppression around balun-transformers
• General electromagnetic interference mitigation on signal cables

Procurement Notes

Verify the specific impedance requirements against application data sheets to ensure compatibility with target frequency bands. Confirm that the multi-aperture dimensions accommodate the physical diameter of the cables being treated. Ensure compliance with relevant environmental standards such as RoHS and REACH during sourcing.

Selection Notes

Choose this component when retrofitting EMI suppression onto existing cable assemblies is required. The split design distinguishes it from solid toroidal cores. Select based on the necessary impedance value at 100 MHz and the physical space constraints within the cable routing path.

Part Context

This component belongs to the WE-RIB product line from Würth Elektronik, which specializes in passive components for electronic systems.
