74270115

Overview

The Würth Elektronik part number 74270115 is a WE-TOF series EMI suppression toroidal ferrite core. It features a cylindrical geometry with an outer diameter of 31.5 mm and a length of 16 mm. The component utilizes material formulation designed for high-frequency noise attenuation, providing an impedance of 80 Ω at 25 MHz and 350 Ω at 100 MHz. This passive component serves as a common-mode choke to suppress electromagnetic interference on cables passing through its central aperture.

Feature Summary

• Provides effective electromagnetic interference suppression in the high-frequency spectrum
• Utilizes specialized ferrite material formulation for targeted noise attenuation
• Features a robust cylindrical toroidal design suitable for cable wrapping

Applications

• Suppression of electromagnetic interference on power supply lines
• Noise filtering on data communication cables
• Common-mode choke applications in industrial electronics

Procurement Notes

Verify the specific impedance characteristics against project requirements, noting the 80 Ω value at 25 MHz and 350 Ω at 100 MHz. Confirm that the physical dimensions, specifically the 31.5 mm outer diameter and 16 mm length, accommodate the target cable bundle. Ensure compliance with relevant environmental standards such as RoHS before finalizing procurement orders.

Selection Notes

Select this component when high-frequency noise suppression is required for cables fitting within the core's aperture. The WE-TOF series offers a balance of impedance performance and mechanical durability. Consider the 80 Ω @ 25 MHz rating for lower frequency noise sources and the higher impedance at 100 MHz for broader spectrum attenuation compared to standard bead solutions.

Part Context

This component belongs to the WE-TOF family of EMI suppression toroidal ferrites from Würth Elektronik. These cores are engineered for general-purpose noise reduction across various electronic assemblies. The 74270115 variant specifically targets applications requiring moderate to high impedance in the tens to hundreds of megahertz range without introducing significant DC resistance or saturation issues.
