7427018

Overview

The Würth Elektronik 7427018 is a WE-TOF series toroidal ferrite core designed for electromagnetic interference suppression. It features an inner diameter of 10.2 mm, an outer diameter of 18.6 mm, and a height of 6 mm. The component utilizes 4W1500 material composition to provide effective noise attenuation in the frequency range between 25 MHz and 100 MHz. It carries RoHS and REACH compliance certifications.

Feature Summary

• Toroidal geometry facilitates easy cable threading for EMI suppression applications
• Constructed from 4W1500 ferrite material optimized for high-frequency noise reduction
• Compliant with RoHS and REACH environmental standards

Applications

• Electromagnetic interference suppression
• Cable noise filtering
• General electronic equipment signal integrity enhancement

Procurement Notes

Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure accuracy. Confirm that the required material grade (4W1500) and physical dimensions match the design specifications. Check for current regulatory compliance status regarding RoHS and REACH requirements before finalizing procurement decisions.

Selection Notes

Select this component when a toroidal form factor is required for through-cable EMI mitigation. Ensure the target frequency range aligns with the 25 MHz to 100 MHz operational window. Verify that the cable bundle diameter fits within the 10.2 mm inner diameter constraint without excessive force or loose fit.

Part Context

This component belongs to the WE-TOF series of EMI suppression toroidal ferrites from Würth Elektronik. These cores are distinct from clamp-on filters as they require cables to be threaded through the center hole during assembly. They serve as passive components to attenuate common-mode noise on data and power lines.

Replacement Considerations

No publicly confirmed substitute part numbers are available in the provided source data. Consult official distributor catalogs for cross-references based on identical impedance characteristics and physical dimensions.
