74270181

Overview

The Wurth Elektronik part number 74270181 is a WE-TOF series EMI suppression toroidal ferrite core. It features a cylindrical solid design with an inner diameter of 10.7 mm and an outer diameter of 12.7 mm. The component utilizes 4W1500 material composition to provide effective noise attenuation. Its impedance characteristics are specified at 83 ohms at 100 MHz and 59 ohms at 25 MHz, making it suitable for suppressing electromagnetic interference on wires and coaxial cables.

Feature Summary

• Solid cylindrical toroidal geometry designed for direct wire insertion
• Utilizes 4W1500 ferrite material for high-frequency noise suppression
• Engineered for use with wires and coaxial cables in EMI mitigation applications

Applications

• EMI suppression on signal wires
• Noise filtering for coaxial cables
• Wire-wrapping cable protection

Procurement Notes

Verify the specific impedance values and physical dimensions against the official manufacturer datasheet before integration. Confirm that the 4W1500 material grade aligns with the target frequency range requirements. Ensure compatibility with the cable outer diameter relative to the 10.7 mm inner diameter specification.

Selection Notes

Select this component when a solid toroidal form factor is required for easy installation onto existing cabling without cutting. The 4W1500 material offers a balance of permeability and resistivity suitable for general-purpose EMI suppression. Consider the 83 ohm impedance at 100 MHz as the primary metric for high-frequency attenuation needs.
