7427140

Overview

The Wurth Elektronik 7427140 is a snap-on ferrite ring designed for cable noise suppression. It features a round design with a hinged plastic case and an inner diameter of 10.2 mm. The component provides an impedance of 98 Ohms at 100 MHz, utilizing a specific ferrite material composition to ensure effective attenuation across the target frequency range. Its external dimensions are 31.00 mm in diameter, suitable for standard cable sizes.

Feature Summary

• Hinged snap-on design for rapid installation on cables without disconnection
• Round geometry optimized for uniform magnetic flux distribution around conductors
• Integrated plastic housing protects internal ferrite material from mechanical damage

Applications

• Cable noise suppression in electronic assemblies
• EMI filtering for data transmission lines
• General electromagnetic interference mitigation in industrial equipment

Procurement Notes

Verify the exact part number suffix against official distributor catalogs to confirm dimensional tolerances and material specifications. Ensure the selected variant matches the required inner diameter for the target cable assembly. Cross-reference the impedance curve in the datasheet to validate performance at the specific operating frequency of the application.

Selection Notes

Select this component when a quick-install solution is required for cables up to 10.2 mm in diameter. The 98 Ohm impedance at 100 MHz indicates suitability for high-frequency noise reduction. Consider the physical size constraints of the enclosure to accommodate the 31.00 mm outer diameter profile during the layout phase.

Part Context

This component belongs to the snap-on ferrite ring category within Wurth Elektronik's passive components portfolio. It serves as a hardware accessory for EMI control, distinct from through-hole or surface-mount filters. The product line focuses on providing flexible, field-installable shielding solutions for various cable types.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility by matching the inner diameter, impedance characteristics, and mounting style before considering alternative manufacturers.
