74271222S

Overview

The Wurth Elektronik 74271222S is a STAR-TEC series snap-on ferrite core designed for electromagnetic interference suppression. It features a hinged design with a safety key mechanism and utilizes 4W620 material. The component has a 13 mm inner diameter and single opening. Electrical characteristics include an impedance of 151 Ω at 25 MHz and 270 Ω at 100 MHz. Physical dimensions are 42.2 mm width, 33.5 mm height, and 28.8 mm depth.

Feature Summary

• Hinged snap-on construction with integrated safety key technology for secure cable retention
• Utilizes 4W620 ferrite material for effective high-frequency noise attenuation
• Single opening configuration allows for easy installation on existing cables

Applications

• Electromagnetic interference suppression
• General electronic applications
• Safety-related applications

Procurement Notes

Verify the specific suffix 'S' to confirm the inclusion of the safety key feature, as standard variants may lack this mechanism. Ensure the 13 mm aperture matches the target cable diameter. Confirm compliance requirements such as RoHS and REACH status against project specifications before finalizing procurement.

Selection Notes

Select this component when a secure, non-loosening ferrite solution is required for cables up to 13 mm in diameter. The 4W620 material offers specific impedance characteristics suitable for general EMI suppression. Consider the physical envelope of 42.2 x 33.5 x 28.8 mm for spatial constraints in the assembly.

Part Context

This part belongs to the Wurth Elektronik STAR-TEC series, which specializes in snap-on ferrite cores. The series distinguishes itself through the integration of safety keys to prevent accidental opening. The 74271222S specifically addresses the need for reliable noise suppression in environments where vibration or movement might compromise standard clamp-on cores.
