WLBD1005HCU800TL

Overview

The WLBD1005HCU800TL is a surface-mount ferrite bead manufactured by Walsin Technology Corporation. It features an 0402 (1005 metric) package size, designed for compact electronic circuits. The component provides an impedance of 80 ohms at 100 MHz, serving as a key element for noise suppression in high-frequency signal lines. It supports a maximum DC current rating of 300 mA and maintains a low DC resistance to minimize power loss during operation.

Feature Summary

• Provides effective electromagnetic interference filtering through high impedance characteristics at target frequencies
• Compact 0402 footprint enables integration into space-constrained printed circuit board layouts
• Low DC resistance design preserves signal integrity while attenuating unwanted noise

Applications

• Noise suppression in mobile phone data lines
• Filtering in portable digital camera circuits
• Signal conditioning in personal computer peripheral interfaces

Procurement Notes

Verify the complete part number including tolerance and tape/reel specifications against official Walsin documentation before ordering. Confirm that the requested impedance value and current ratings align with specific circuit requirements. Ensure compatibility with standard surface mount assembly processes.

Selection Notes

Select this component based on required impedance at operating frequency and available board space. Evaluate DC current capacity against peak load conditions to prevent saturation. Consider thermal performance and mounting orientation relative to surrounding components for optimal heat dissipation.

Part Context
