74271722

Overview

The Wurth Elektronik 74271722 is a snap-on ferrite core from the STAR-FIX series, designed for electromagnetic interference suppression. It features a split-core design with a flexible cable fixing mechanism, accommodating cables with diameters between 8.5 mm and 12.5 mm. The component utilizes NiZn material to provide high impedance, specifically 151 Ohms at 25 MHz and 270 Ohms at 100 MHz. Its physical dimensions are 31.5 mm in height, 35 mm in width, and it operates within a temperature range of -50°C to +105°C.

Feature Summary

• Snap-on design with integrated flexible cable fixing for rapid installation
• Split-core construction allowing placement on existing cables without disconnection
• NiZn material composition optimized for high-frequency noise attenuation

Applications

• Electromagnetic compatibility security for cable assemblies
• Suppression of electromagnetic interference in electronic equipment
• Noise reduction on cables with diameters between 8.5 mm and 12.5 mm

Procurement Notes

Verify the specific impedance value required for your application, as datasheets may list 151 Ohms at 25 MHz or 270 Ohms at 100 MHz depending on the test frequency context. Confirm that the target cable diameter falls strictly within the 8.5 mm to 12.5 mm range to ensure proper fit and performance. Check for RoHS compliance status if environmental regulations apply to your project.

Selection Notes

Select this component when quick installation on pre-existing cables is necessary. The snap-on mechanism eliminates the need for tools or cable cutting. Ensure the operating environment temperature stays within -50°C to +105°C. Choose based on the required impedance profile at your specific noise frequency, typically 25 MHz or 100 MHz for general EMI suppression.
