74275815S

Overview

The Würth Elektronik 74275815S is a snap-on ferrite core from the WE-STAR-BUENO series, designed for EMI suppression on cables with diameters between 4.5 mm and 8.5 mm. It features an optical closing control mechanism to ensure secure installation. The component provides an impedance of 350 ohms at 1 MHz and operates within a temperature range of -25°C to +105°C. Constructed from black ferrite material, it has an outer diameter of 24 mm and complies with RoHS standards.

Feature Summary

• Features an optical closing control mechanism for visual verification of secure attachment
• Designed for rapid snap-on installation onto cables without tools
• Provides effective electromagnetic interference suppression in the specified frequency range

Applications

• Cable shielding for electronic equipment
• EMI suppression on data and power lines
• Industrial control system wiring

Procurement Notes

Verify the specific part number suffix against official Wurth Elektronik documentation to confirm exact impedance characteristics and physical dimensions. Ensure compatibility with the target cable diameter range of 4.5 mm to 8.5 mm before procurement. Cross-reference the manufacturing date code to ensure compliance with current environmental regulations such as RoHS. Confirm that the optical closure feature meets the assembly quality requirements for the intended application.

Selection Notes

Select this component when a quick-install solution is required for cables within the 4.5 mm to 8.5 mm diameter range. The optical closure mechanism offers a distinct advantage for quality assurance during assembly by providing immediate visual confirmation of proper engagement. Consider the 350 ohm impedance at 1 MHz for typical EMI noise frequencies. Evaluate the operating temperature range of -25°C to +105°C against the environmental conditions of the deployment site.

Part Context

This component belongs to the WE-STAR-BUENO series of snap-on ferrites from Würth Elektronik. These cores are engineered for easy retrofitting and maintenance of existing cable assemblies. The series emphasizes user-friendly installation through mechanical design features like the optical closure indicator, distinguishing it from standard split-core designs that require manual locking mechanisms or adhesives.
