7427020

Overview

The Würth Elektronik part number 7427020 is a split-core ferrite core designed for electromagnetic interference (EMI) suppression. It belongs to the WE-SPLITRING series and utilizes 4W620 material composition. The component features an internal diameter of 8.2 mm and provides an impedance of 93 Ω at 100 MHz. It is packaged in trays and supports rapid installation on existing cables without disconnection.

Feature Summary

• Split-core design allows installation on terminated cables without circuit interruption
• Utilizes 4W620 ferrite material for effective high-frequency noise attenuation
• Provides standardized 93 Ω impedance performance at 100 MHz

Applications

• Electromagnetic interference suppression on data cables
• Noise filtering for power supply lines
• Signal integrity enhancement in digital equipment

Procurement Notes

Verify that the target cable diameter does not exceed the 8.2 mm internal aperture to ensure proper mechanical fit. Confirm that the application frequency range aligns with the specified 93 Ω impedance characteristic at 100 MHz. Check packaging specifications, as the component is supplied in tray packaging rather than bulk reels. Ensure compliance with REACH and RoHS directives if required by the end-product regulations.

Selection Notes

Select this component when non-invasive installation on pre-terminated cables is required. The 8.2 mm bore size accommodates standard ribbon or multi-conductor cables. Choose this specific model over solid cores when field modification or retrofitting is necessary. The 4W620 material offers a balance of permeability and resistivity suitable for general-purpose EMI mitigation in commercial electronics.

Part Context

This component is part of the WE-SPLITRING series from Würth Elektronik, which specializes in snap-on ferrite solutions. Unlike traditional solid toroids, these split cores enable maintenance and assembly flexibility. The series complements the manufacturer's broader portfolio of fixed ferrite beads and clip-on chokes used in industrial and consumer applications.
