74272485

Overview

The Würth Elektronik part number 74272485 is a snap-open flat ferrite core belonging to the WE-STAR-FLAT series. It is constructed from 4W620 material and provides an impedance of 101 Ohms at 25 MHz. The component features a grey color and measures 52 mm in length. Designed for cable suppression, it utilizes a snap-open mechanism for installation without disconnecting cables.

Feature Summary

• Snap-open design allows installation on existing cables without disconnection
• Flat geometry suitable for space-constrained applications
• Utilizes 4W620 ferrite material for effective noise suppression

Applications

• Cable noise suppression
• EMI filtering for data lines
• Power cable interference reduction

Procurement Notes

Verify the specific impedance value and frequency rating against the official datasheet before integration. Confirm that the physical dimensions match the available clearance in the target assembly. Ensure the snap mechanism integrity is sufficient for the intended environmental conditions.

Selection Notes

Select this component when a low-profile solution is required for suppressing electromagnetic interference on flat or bundled cables. The snap-open feature facilitates retrofitting into existing harnesses. Compare the 101 Ohm impedance profile against the specific noise frequencies present in the application to ensure adequate attenuation performance.

Part Context

This component is part of the WE-STAR-FLAT series from Würth Elektronik. It serves as a passive EMI suppression device designed for quick installation on cables. The flat shape distinguishes it from cylindrical ring cores, offering a different form factor for specific routing requirements.
