74270182

Overview

The Würth Elektronik 74270182 is a cylindrical EMI suppression toroidal ferrite core from the WE-TOF series. It is constructed using 4W1500 material and provides an impedance of 65 Ω at 10 MHz and 55 Ω at 25 MHz. The component features a solid design with an inner diameter of 10.2 mm and an outer diameter of 26.5 mm. It is suitable for suppressing electromagnetic interference on wires, coaxial cables, and wire-wrapping applications.

Feature Summary

• Solid cylindrical toroidal geometry for secure cable retention
• Engineered for effective EMI suppression on various cable types
• Utilizes 4W1500 ferrite material composition

Applications

• Wires
• Coaxial cables
• Wire-wrapping applications

Procurement Notes

Verify the specific impedance requirements against the datasheet curves for 10 MHz and 25 MHz. Confirm that the 10.2 mm inner diameter accommodates the target cable bundle. Ensure the application environment is compatible with the standard ferrite material properties. Cross-reference the part number to confirm current manufacturing status and availability through authorized channels.

Selection Notes

Select this component when a solid, non-hinged toroidal core is required for permanent installation on cables. The 10.2 mm bore size dictates the maximum cable diameter. Choose based on the specific attenuation needs provided by the 4W1500 material characteristics at the operating frequency range. This model is distinct from hinged or split-core alternatives.

Part Context

This part belongs to the WE-TOF series of toroidal ferrite cores manufactured by Würth Elektronik. These components are designed for general-purpose electromagnetic interference suppression in electronic assemblies.
