7427809

Overview

The Würth Elektronik part number 7427809 is a solid flat ferrite core belonging to the WE-FLAT series. It provides an impedance of 50 Ohms at a test frequency of 100 MHz. The component features an internal width of 17 mm and an internal height of 0.8 mm, with external dimensions measuring 21 mm in length, 8 mm in width, and 5 mm in height. Constructed from 4W620 material, it operates within a temperature range of -25°C to +125°C.

Feature Summary

• Solid construction designed specifically for flat ribbon cables
• Utilizes 4W620 ferrite material for EMI suppression
• RoHS compliant manufacturing standard

Applications

• Flat ribbon cable interference mitigation
• Digital equipment signal line protection
• General EMI suppression on data lines

Procurement Notes

Verify the specific manufacturer part number 7427809 against official Wurth Elektronik documentation to confirm technical specifications. Ensure compatibility with flat ribbon cable dimensions before integration. Cross-reference datasheets for material composition and impedance characteristics to validate performance requirements for the intended application environment.

Selection Notes

Select this component when shielding flat ribbon cables requires a solid core solution rather than split types. The 0.8 mm internal height accommodates thin flat cables. Consider the 50 Ohm impedance at 100 MHz for high-frequency noise attenuation needs. Verify thermal operating limits align with the system environment constraints.

Part Context

This component is part of the WE-FLAT series from Würth Elektronik, specialized for flat cable applications. It serves as a passive electromagnetic interference suppression element. The design focuses on easy installation over existing flat cabling without requiring disconnection or complex mounting hardware.
