74270118

Overview

The Wurth Elektronik part number 74270118 is a WE-TOF series toroidal ferrite core designed for EMI suppression. It features an inner diameter of 12.7 mm, an outer diameter of 21.2 mm, and a height of 6 mm. The component utilizes 3 W 800 ferrite material and operates within a frequency range from 25 MHz to 100 MHz.

Feature Summary

• Provides electromagnetic interference suppression through high-frequency impedance characteristics
• Designed for cable wrapping applications including multi-wire, coaxial, and single wires
• Utilizes specific ferrite material composition for targeted frequency attenuation

Applications

• Cable wrapping for EMI reduction
• Multi-wire cable suppression
• Coaxial cable noise filtering
• General wire harness protection

Procurement Notes

Verify the manufacturer part number 74270118 against official Wurth Elektronik documentation to confirm specifications. Ensure compatibility with cable diameters up to 12.7 mm. Check for RoHS compliance status in current datasheets. Confirm material grade 3 W 800 matches design requirements for the target frequency band.

Selection Notes

Select this component when solid toroidal geometry is required for permanent cable installation. The 12.7 mm aperture accommodates cables that cannot fit into split-core alternatives. Consider the fixed dimensions and material properties for space-constrained environments requiring robust EMI shielding without moving parts.

Part Context

This component belongs to the WE-TOF series of ferrite rings manufactured by Wurth Elektronik. These cores are distinct from snap-on types due to their solid construction. They are intended for applications where cables can be threaded through the center hole during assembly rather than after routing.

FAQ

What is the operating frequency range for this ferrite core?

The component is specified for operation between 25 MHz and 100 MHz.

Can this core be installed on already routed cables?

No, it is a solid toroid requiring the cable to be threaded through the 12.7 mm inner diameter before final placement.
