74270113

Overview

The Wurth Elektronik 74270113 is a WE-TOF series EMI suppression toroidal ferrite core constructed from 4W620 material. It features a cylindrical design with an inner diameter of 5 mm, an outer diameter of 11.5 mm, and a height of 9 mm. The component provides an impedance of 68 Ω at 25 MHz and 405 Ω at 100 MHz. It operates within a frequency range of 25 MHz to 100 MHz and complies with RoHS and REACH standards.

Feature Summary

• Provides effective electromagnetic interference suppression for wires and coaxial cables
• Constructed from 4W620 ferrite material optimized for high-frequency noise attenuation
• Designed for easy installation around conductors without requiring disconnection

Applications

• EMI suppression for individual wires
• Noise filtering for coaxial cables
• General electromagnetic interference mitigation in electronic assemblies

Procurement Notes

Verify the specific impedance requirements against the application's noise spectrum before ordering. Confirm that the 5 mm inner diameter accommodates the target cable or wire bundle dimensions. Ensure compliance with RoHS and REACH regulations is required for the intended market. Cross-reference the manufacturer part number 74270113 to avoid confusion with similar WE-TOF variants.

Selection Notes

Select this component when the application requires a compact toroidal solution for frequencies between 25 MHz and 100 MHz. The 5 mm bore size limits suitability to smaller gauge wires or bundled cables fitting within the aperture. Consider the 4W620 material properties for balancing impedance magnitude and frequency response. Evaluate spatial constraints given the 11.5 mm outer diameter and 9 mm height profile.
