74272733

Overview

The Würth Elektronik 74272733 is a STAR-FIX LFS snap ferrite core designed for low-frequency electromagnetic interference suppression. It features a manganese-zinc (MnZn) core material and an impedance of 62 Ω at 100 MHz. The component has an internal diameter of 8 mm and includes a patented flexible cable fixing mechanism with a safety lock.

Feature Summary

• Patented flexible cable fixing system with integrated safety lock
• Designed for low-frequency noise suppression applications
• Snap-on installation design for rapid deployment

Applications

• Low frequency EMI suppression
• Cable noise filtering in digital equipment
• Flat cable protection

Procurement Notes

Verify the specific datasheet version to confirm the exact impedance tolerance and operating temperature range. Ensure the 8 mm aperture matches the target cable bundle diameter. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when low-frequency noise attenuation is required alongside secure mechanical retention. The integrated safety lock prevents accidental disengagement during handling or operation. Verify that the 62 Ω impedance characteristic aligns with the targeted interference spectrum for optimal performance.

Part Context

This part belongs to the STAR-FIX LFS series, which specializes in snap-on ferrites with enhanced mechanical stability. Unlike standard split cores, it incorporates a unique locking mechanism to ensure the ferrite remains securely closed around the cable, providing reliable long-term EMI shielding without additional fasteners.

Replacement Considerations

No public confirmed substitute part numbers are available.
