74270198

Overview

The Würth Elektronik part number 74270198 is a cylindrical ferrite core belonging to the WE-TOF series, designed for EMI suppression. It features an inner diameter of 35.3 mm and an outer diameter of 61 mm, with a total length of 12.7 mm. The component exhibits an impedance of 400 ohms. Constructed from high-performance ferrite material, this solid toroidal ring provides effective noise attenuation for power cables and conductors without requiring split installation mechanisms.

Feature Summary

• Solid cylindrical geometry eliminates the need for clamping tools or opening mechanisms during installation.
• High impedance characteristic of 400 ohms ensures effective suppression of electromagnetic interference across targeted frequency ranges.
• Robust construction suitable for securing noise on power lines and data cables in industrial environments.

Applications

• EMI suppression on power cables
• Noise filtering for general electronic equipment conductors
• Industrial control system wiring protection

Procurement Notes

Verify the specific impedance value and dimensional tolerances against the official manufacturer datasheet prior to integration. Confirm that the cable diameter falls within the 35.3 mm inner diameter specification to ensure proper fit. Check for RoHS compliance status as documented in the latest product release notes to meet regulatory requirements.

Selection Notes

Select this model when a non-split, solid ferrite solution is required for cables that can be threaded through the center bore. Compare the 400 ohm impedance profile against alternative materials if higher attenuation at specific frequencies is needed. Ensure physical clearance allows for the 61 mm outer diameter and 12.7 mm length constraints within the assembly layout.

Part Context

This component is part of the WE-TOF series from Würth Elektronik, which specializes in toroidal ferrite cores for electromagnetic interference suppression. The series offers various dimensions and impedance ratings to accommodate different cable sizes and noise profiles. The 74270198 variant specifically targets applications requiring a robust, fixed-diameter core for larger gauge cabling.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users should consult the manufacturer's cross-reference tools or datasheets for equivalent products with matching impedance and dimensional specifications.
