74270119

Overview

The Würth Elektronik 74270119 is a cylindrical toroidal ferrite core from the WE-TOF series, designed for EMI suppression. Constructed from 3W800 material, it features an inner diameter of 13.3 mm and outer dimensions of 22.5 mm. The component provides an impedance of 45 Ω at 25 MHz and 133 Ω at 100 MHz, with a total impedance reaching 398 Ω. It is suitable for suppressing noise on wires and coaxial cables.

Feature Summary

• Cylindrical toroidal geometry for uniform magnetic flux distribution
• High impedance performance across specified frequency ranges
• Compatible with standard wire and coaxial cable applications

Applications

• EMI suppression for general wiring
• Noise filtering for coaxial cables
• Wire-wrapping applications

Procurement Notes

Verify the specific impedance requirements against the datasheet values of 45 Ω at 25 MHz and 133 Ω at 100 MHz. Confirm that the 13.3 mm inner diameter accommodates the target cable or wire bundle. Ensure the 3W800 material composition meets the thermal and frequency constraints of the intended circuit environment before finalizing procurement.

Selection Notes

Select this component when a cylindrical form factor is required for through-hole or manual assembly processes. The WE-TOF series offers high impedance density suitable for broadband noise suppression. Compare the 13.3 mm aperture size against alternative series like STAR-RING if snap-fit installation is preferred over sliding onto cables.

Part Context

This part belongs to the WE-TOF series of toroidal ferrite cores manufactured by Würth Elektronik. These components are distinct from split-core designs, requiring the cable to be threaded through the center during assembly. The series utilizes specific ferrite formulations optimized for high-frequency attenuation in electronic interconnects.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Alternative solutions may require matching the 13.3 mm ID and 133 Ω @ 100 MHz impedance specifications from other manufacturers.
