742863147

Overview

The Würth Elektronik WE-CBF HF 742863147 is a surface-mount EMI suppression ferrite bead designed for high-frequency noise attenuation. It features a compact 0603 [1608 Metric] package and delivers an impedance of 470 ohms at 100 MHz. The component supports a maximum DC current of 500 mA with a maximum DC resistance of 0.32 ohms. Its modified internal layout enhances effective suppression capabilities, making it suitable for applications requiring efficient signal integrity maintenance in dense circuit layouts.

Feature Summary

• High-frequency EMI noise suppression via modified internal layout
• Compact 0603 surface-mount footprint for space-constrained designs
• Low DC resistance to minimize power loss in signal paths

Applications

• High-speed data line filtering
• RF interference suppression in portable electronics
• Signal integrity protection in communication modules

Procurement Notes

Verify the specific impedance tolerance and current ratings against your circuit requirements before ordering. Confirm that the 0603 package dimensions align with your PCB land pattern specifications. Ensure compatibility with your assembly process regarding peak reflow temperatures. Cross-reference the manufacturer datasheet for detailed handling and storage conditions to maintain component reliability.

Selection Notes

Select this component when high impedance at 100 MHz is required within a minimal footprint. The 500 mA current rating suits low-power signal lines rather than high-current power rails. Consider the 0.32 ohm DC resistance impact on voltage drop. Evaluate the WE-CBF HF series alternatives if different impedance profiles or current capacities are needed for the target application.

Part Context

This part belongs to the WE-CBF HF series, which specializes in high-frequency EMI suppression. The series offers various impedance values and current ratings in standard SMD packages. Würth Elektronik designs these components to address noise issues in modern high-speed digital and RF circuits, providing reliable performance in compact electronic devices.

Replacement Considerations

Direct substitutes include other 0603 ferrite beads with 470 ohms impedance at 100 MHz and similar current ratings. Verify pinout compatibility and physical dimensions before replacing. Check if alternative manufacturers offer equivalent impedance curves and thermal characteristics for seamless integration.
