74271112

Overview

The Wurth Elektronik 74271112 is a STAR-TEC Snap ferrite core designed for cable applications. It features a hinged design with safety key technology, allowing the core to be opened and reattached easily. The component has an inner diameter of 6 mm and measures 32.5 mm in length, 18.8 mm in width, and 13.2 mm in height. It provides an impedance of 176 Ω at 25 MHz and 321 Ω at 1 MHz. The housing is made of white PA6-GF30 material, while the core utilizes 4W620 ferrite material.

Feature Summary

• Patented safety key technology enables quick opening and secure reattachment of the hinged ferrite core.
• Snap-fit design facilitates rapid installation on existing cables without disconnection.
• High impedance characteristics provide effective suppression of high-frequency electromagnetic interference.

Applications

• General electronic equipment
• External cable protection
• Internal cable management

Procurement Notes

Verify the specific impedance requirements against the datasheet values of 176 Ω at 25 MHz and 321 Ω at 1 MHz. Confirm that the 6 mm inner diameter accommodates the target cable size. Ensure the white PA6-GF30 housing meets environmental standards such as RoHS and REACH compliance for the intended application.

Selection Notes

Select this model when retrofitting ferrite suppression onto existing cables is required due to its snap-open mechanism. The 6 mm aperture suits smaller gauge wires. Consider the 176 Ω impedance at 25 MHz for typical noise frequencies. The hinged design eliminates the need to thread cables through solid cores, saving assembly time.
