74271622S

Overview

The Würth Elektronik 74271622S is a snap-on ferrite core from the STAR-GAP series, designed for high-frequency noise suppression. It utilizes 4W620 material and features a square cross-section with an internal diameter of 12.5 mm. The component measures 32.5 mm in length, 30.3 mm in width, and 28.2 mm in height. It provides an impedance of 140 Ω at 100 MHz and 35 Ω at 25 MHz. The design includes a key slot for secure closure.

Feature Summary

• Snap-on design with integrated key for secure installation
• Optimized impedance performance for two-winding configurations
• Square cross-section geometry for uniform magnetic field distribution

Applications

• High-speed data line noise suppression
• RF interference mitigation
• Cable filtering in electronic assemblies

Procurement Notes

Verify the specific suffix designation against official documentation to confirm exact impedance characteristics and physical tolerances. Ensure the selected variant matches the required aperture size and mounting constraints for the target application.

Selection Notes

Select this component when a snap-on solution is preferred over split-core types requiring tools. The STAR-GAP series offers consistent performance for common mode chokes. Confirm that the 12.5 mm inner diameter accommodates the cable bundle without excessive air gap variation.

Part Context

This part belongs to the STAR-GAP family of ferrite clamps. These components are engineered for rapid deployment on cables where permanent attachment is not feasible. The series covers various aperture sizes to suit different cable diameters while maintaining standardized impedance profiles.

Replacement Considerations

No public confirmed substitute part numbers are available.
