74270161

Overview

The Wurth Elektronik 74270161 is a cylindrical ferrite core belonging to the WE-TOF series. It features an outer diameter of 10 mm, an inner diameter of 5 mm, and a length of 3.7 mm. The component exhibits an impedance of 25 Ω at 25 MHz and 136 Ω at higher frequencies within its operational range. Constructed for EMI suppression, it provides effective noise reduction for signal and power lines.

Feature Summary

• Cylindrical geometry designed for direct cable insertion without tools
• High impedance characteristics for effective electromagnetic interference suppression
• Compact dimensions suitable for space-constrained electronic assemblies

Applications

• Signal line noise filtering
• Power cable EMI suppression
• General electromagnetic compatibility enhancement

Procurement Notes

Verify the specific impedance curve against application frequency requirements. Confirm that the 5 mm inner diameter accommodates the target cable insulation thickness. Ensure compliance with RoHS standards if required by the end product specifications.

Selection Notes

Select this part when a low-profile, tool-free ferrite solution is needed for cables up to 5 mm in diameter. Compare impedance values at operating frequencies against alternative toroidal or snap-on designs to ensure adequate attenuation for the specific noise spectrum encountered.

Part Context

This component is part of the WE-TOF family of cylindrical ferrite cores from Wurth Elektronik. These cores are distinct from snap-on rings due to their solid cylindrical shape, requiring manual installation over cable ends rather than clamping around existing wires.

FAQ

What is the inner diameter of the 74270161 core?

The inner diameter is 5 mm.

Does this component require a locking mechanism?

No, it is a solid cylindrical core that requires manual sliding onto the cable end.
