74271151S

Overview

The Würth Elektronik 74271151S is a snap-on ferrite core from the STAR-TEC series, designed for cable noise suppression. It features a round shape with an inner diameter of 15 mm and an outer diameter of 39 mm. The external dimensions are 49 mm in length, 38.8 mm in height, and 15 mm in internal height. Constructed from 4W620 ferrite material, it provides an impedance of 417 Ohms at 100 MHz and 145 Ohms at 25 MHz. The component operates within a temperature range of -25°C to +105°C and includes a safety key.

Feature Summary

• Snap-on design with integrated safety key for secure cable retention
• Round cross-section geometry optimized for single cable installation
• High impedance performance using 4W620 ferrite material composition

Applications

• General electronic equipment cable noise suppression
• Power cable EMI filtering
• Data line interference reduction

Procurement Notes

Verify the specific impedance value required for your application against the datasheet specifications at 25 MHz and 100 MHz. Confirm that the 15 mm inner diameter accommodates the target cable bundle size. Ensure the operating environment falls within the specified -25°C to +105°C temperature range. Check for RoHS compliance requirements if applicable to your manufacturing standards.

Selection Notes

Select this component when a snap-on solution is preferred over split-core designs for ease of installation on existing cables. The 15 mm aperture suits medium-sized cable bundles. Consider the 417 Ohm impedance at 100 MHz for high-frequency noise attenuation needs. The safety key feature prevents accidental disengagement during vibration or handling.
