74271132

Overview

The Würth Elektronik 74271132 is a snap-on ferrite core from the STAR-TEC series, designed for rapid installation on cables. It features an internal diameter of 8.5 mm and utilizes 4W620 material composition. The component provides an impedance of 141 Ω at 25 MHz and 100 Ω at 100 MHz. Operating temperatures range from -25 °C to +105 °C. It incorporates safety key technology for secure attachment.

Feature Summary

• Snap-on design with integrated safety key mechanism for secure cable retention
• Utilizes 4W620 ferrite material for effective high-frequency noise suppression
• Square shape construction suitable for direct cable clamping

Applications

• General EMI/RFI noise suppression on cables
• Safety-related electronic applications
• Power supply cable filtering

Procurement Notes

Verify the specific impedance values against the official datasheet, as distributor listings may vary or contain errors. Confirm the material grade is 4W620. Ensure the operating temperature range meets your environmental requirements. Check for RoHS compliance status in the latest documentation before finalizing procurement.

Selection Notes

Select this part when a quick-install solution is required for cables up to 8.5 mm in diameter. The 141 Ω impedance at 25 MHz makes it suitable for suppressing noise in that frequency band. Consider the square profile for space-constrained areas where round cores do not fit. Verify compatibility with the target cable insulation type.

Part Context

This component belongs to the STAR-TEC series of snap-on ferrites from Würth Elektronik. These cores are engineered for easy manual installation without tools. The series offers various sizes and impedances to address different cable diameters and noise frequencies. The 74271132 variant specifically targets the 8.5 mm cable size category.
