7427002

Overview

The Würth Elektronik 7427002 is a solid round ferrite cable core from the WE-SAFB series, designed for electromagnetic interference suppression. It features an inner diameter of 1.2 mm and an outer diameter of 3.5 mm with a length of 6 mm. The component exhibits an impedance of 65 Ω at 25 MHz and 125 Ω at 100 MHz. Constructed from 3W800 material, it operates within a temperature range of -25°C to +125°C.

Feature Summary

• Solid round design for secure cable retention without hinged mechanisms
• High impedance performance across specified frequency bands for effective noise attenuation
• Compact physical dimensions suitable for tight spatial constraints in wiring harnesses

Applications

• Suppression of common mode noise on signal cables
• EMI filtering in automotive electronic assemblies
• Noise reduction in industrial control wiring

Procurement Notes

Verify the specific impedance requirement against application needs, as datasheets may list values at different frequencies such as 25 MHz or 100 MHz. Confirm package quantity and lead times directly with authorized distributors, as standard delivery periods can vary. Ensure the inner diameter matches the target cable gauge precisely to maintain mechanical stability during operation.

Selection Notes

Select this component when a non-hinged, solid ferrite core is required for permanent installation on cables up to 1.2 mm in diameter. The WE-SAFB series offers consistent magnetic properties suitable for broadband suppression. Consider the operating temperature range and material composition if the environment involves thermal cycling or high ambient heat.

Part Context

This part belongs to the WE-SAFB family of solid ferrite cores manufactured by Würth Elektronik. These components are distinct from hinged types like the STAR-FIX series, offering a simpler installation method for fixed cable runs. The product line focuses on providing reliable EMI protection for various electronic interconnects.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing cable diameters and mounting constraints before considering alternative manufacturers.
