74270110

Overview

The Würth Elektronik 74270110 is a WE-TOF EMI suppression toroidal ferrite core designed for noise reduction. It features an outer diameter of 16 mm, an inner diameter of 12 mm, and a height of 16 mm. The component utilizes material optimized for high-frequency attenuation, providing an impedance of 47 Ω at 25 MHz. This snap-fit design allows for rapid installation on cables without tools, making it suitable for compact electronic assemblies requiring effective electromagnetic interference mitigation.

Feature Summary

• Snap-fit toroidal geometry enables tool-free installation directly onto cables
• Optimized magnetic material composition for effective high-frequency noise suppression
• Compact cylindrical form factor designed for space-constrained electronic applications

Applications

• EMI suppression on power supply cables
• Noise filtering for computer data lines
• General purpose electromagnetic interference mitigation in consumer electronics

Procurement Notes

Verify the specific impedance value at 25 MHz against current manufacturer datasheets prior to ordering. Confirm that the physical dimensions match the target cable bundle size. Ensure compliance with RoHS and REACH standards required by the end product regulations. Cross-reference the part number to avoid confusion with similar series components.

Selection Notes

Select this component when a non-invasive, snap-on solution is required for cable noise reduction. The 12 mm inner diameter dictates the maximum cable thickness. Consider the 47 Ω impedance profile at 25 MHz for frequency-specific attenuation needs. Evaluate spatial constraints as the 16 mm outer diameter requires adequate clearance within the enclosure.

Part Context

This part belongs to the WE-TOF series of EMI suppression toroidal ferrites from Würth Elektronik. These cores are engineered for general-purpose noise suppression across various industrial and consumer applications. The series offers standardized dimensions and material properties to simplify BOM management and ensure consistent performance across different cable diameters.
