742792608

Overview

The Würth Elektronik part number 742792608 is a surface-mount EMI suppression ferrite bead belonging to the WE-CBF series. It features a compact 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 47 ohms at 100 MHz and maintains approximately 75 ohms at 1 GHz. It supports a maximum DC current rating of 500 mA. The device is designed for high-frequency noise attenuation in digital signal lines.

Feature Summary

• Provides effective electromagnetic interference suppression through high impedance characteristics across specified frequency ranges.
• Utilizes a small surface-mount footprint suitable for space-constrained printed circuit board layouts.
• Constructed from specialized ferrite material optimized for broadband noise absorption.

Applications

• Digital signal line filtering
• High-speed data interface protection
• General-purpose EMI suppression

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet prior to integration. Confirm that the selected package size aligns with the automated placement equipment capabilities and the target PCB land pattern specifications to ensure reliable soldering and mechanical stability during operation.

Selection Notes

Select this component when design requirements necessitate a low-profile surface-mount solution for attenuating high-frequency noise on signal traces. The 500 mA current rating defines the operational limit for continuous direct current flow without saturation. Ensure the application frequency spectrum overlaps with the component's peak impedance region for optimal filtering performance.

Part Context

This ferrite bead is part of the WE-CBF product family, which focuses on compact EMI suppression solutions. The series offers various impedance values and current ratings within standard industrial footprints. This specific model addresses the need for noise control in dense electronic assemblies where vertical space is limited.

Replacement Considerations

Cross-reference alternative suppliers for equivalent 0603 ferrite beads with matching 47-ohm impedance at 100 MHz and comparable current handling capabilities. Verify that any substitute component meets the same physical dimension constraints and thermal performance standards required by the original design.
