78271131S

Overview

The Würth Elektronik part number 78271131S is a split core ferrite clamp belonging to the WE-CAR-TEC series. It features a 7.5 mm inner diameter designed for cable diameters ranging from 6.0 mm to 7.5 mm. The component utilizes 4W620 material and provides an impedance of 235 ohms at 100 MHz. It is certified under AEC-Q200 standards, indicating suitability for automotive applications. The unit complies with RoHS and REACH directives.

Feature Summary

• Snap-fit design enables rapid manual installation without tools
• AEC-Q200 certification ensures reliability in automotive environments
• Split core construction allows retrofitting onto existing cables

Applications

• Automotive wiring harness noise suppression
• General EMI filtering for power cables
• Data line interference reduction

Procurement Notes

Verify that the target cable diameter falls within the specified 6.0 mm to 7.5 mm range to ensure proper fit and performance. Confirm that the application requires AEC-Q200 qualified components if used in automotive systems. Check for RoHS compliance requirements specific to the destination market before finalizing procurement orders.

Selection Notes

Select this model when a snap-on ferrite solution is required for cables between 6.0 mm and 7.5 mm in diameter. Choose based on the need for 235 ohms impedance at 100 MHz for high-frequency noise attenuation. Consider the CAR-TEC series for applications demanding quick assembly and robust mechanical retention compared to standard split cores.

Part Context

This component is part of the WE-CAR-TEC series, specifically engineered for automotive and industrial use. It differs from the STAR-TEC series by its specific impedance profile and AEC-Q200 qualification. The 78271131S variant is distinct from similar Wurth parts like 74271131S due to its higher impedance rating and automotive certification status.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing harnesses before attempting substitution with other split core ferrites.
