78271112S

Overview

The Wurth Elektronik 78271112S is a split core ferrite clamp from the WE-CAR-TEC series, designed for automotive-grade electromagnetic interference suppression. It features a hinged snap-on design with a cable diameter range of 4.5 mm to 6.0 mm. The component provides an impedance of 316 ohms at 100 MHz and 64 ohms at 25 MHz. It utilizes 4W620 material and complies with AEC-Q200 standards, REACH, and RoHS regulations.

Feature Summary

• Hinged snap-on design for rapid installation on existing wire harnesses
• Automotive-grade construction compliant with AEC-Q200 standards
• High impedance performance for effective EMI suppression in power cables

Applications

• Automotive wire harness noise suppression
• Power cable filtering in vehicle electrical systems
• General electronic equipment EMI mitigation

Procurement Notes

Verify the specific ordering suffix to confirm compliance requirements and packaging details. Ensure the selected variant matches the required cable diameter range of 4.5 mm to 6.0 mm. Confirm that the component meets the necessary automotive quality standards for the intended application environment.

Selection Notes

Select this component when a non-invasive solution for adding ferrite suppression to existing wiring is required. The split core design allows for installation without disconnecting wires. Choose based on the required impedance profile at target frequencies and the physical dimensions of the cable being treated.

Part Context

This part belongs to the WE-CAR-TEC series, which focuses on automotive applications. It serves as a passive component for managing electromagnetic compatibility issues in complex vehicle electrical architectures, complementing other shielding and filtering solutions.

Replacement Considerations

Consider Wurth Elektronik parts within the STAR-TEC or STAR-RING series for alternative impedance profiles or different cable diameters. Verify cross-compatibility by comparing impedance curves and physical fitment constraints before substitution.
