7427258

Overview

The Wurth Elektronik 7427258 is a split flat ferrite core from the WE-SFA series, designed for electromagnetic interference suppression on ribbon cables. It features a 66 Ohm impedance at 100 MHz and accommodates up to ten poles. The component measures 15 mm in external length, 17 mm in width, and 2.5 mm in height. It operates within a temperature range of -25°C to +125°C and utilizes manganese-zinc material composition.

Feature Summary

• Split design allows installation onto existing flat ribbon cables without disconnecting connectors
• Provides high attenuation for common mode noise across wide frequency bands
• Solid construction ensures stable performance under varying thermal conditions

Applications

• Suppression of electromagnetic interference on parallel data buses
• Noise reduction on internal computer ribbon cables
• EMI mitigation in industrial control panel wiring harnesses

Procurement Notes

Verify the specific impedance value and pole capacity against the official datasheet before integration. Confirm that the physical dimensions match the available space in the assembly. Ensure the operating temperature range meets the environmental requirements of the final application. Check for RoHS compliance status if required by regulatory standards.

Selection Notes

Choose this component when retrofitting EMI suppression onto pre-assembled flat cable assemblies. The split design eliminates the need to dismantle connections during installation. Select based on the required impedance profile at the target noise frequencies. Ensure the cable thickness fits within the core aperture limits.
