7427153S

Overview

The Würth Elektronik 7427153S is a snap-on ferrite core from the STAR-RING series, designed for EMI suppression on cables. It features a split design with an integrated safety key mechanism to prevent unauthorized removal. The component utilizes 4W620 material and provides an impedance of 64 Ω at 25 MHz and 119 Ω at 100 MHz. It has a central aperture diameter of 14.5 mm and external dimensions of 40 mm x 30 mm x 20 mm. The housing is constructed from UL 94-V0 rated plastic.

Feature Summary

• Snap-on split design with integrated safety key for secure installation
• High-impedance 4W620 material for effective EMI/RFI noise suppression
• UL 94-V0 rated plastic housing for fire safety compliance

Applications

• Power supply cables
• Computer data lines
• Circuit board wiring

Procurement Notes

Verify the exact part number suffix against official Wurth Elektronik documentation to confirm specifications. Ensure the required safety key tool is available for installation. Confirm RoHS and REACH compliance status directly from the manufacturer's datasheet before procurement.

Selection Notes

Select this component when cable diameters fit within the 14.5 mm aperture. Choose based on required impedance characteristics at specific frequencies. Consider the integrated safety key feature if tamper resistance is necessary for the application environment.

Part Context

This component belongs to the STAR-RING series of snap-on ferrites. It is distinct from solid cores due to its hinged design, allowing installation on existing cables without disconnection. The inclusion of a safety key differentiates it from standard snap-on variants.
