WLBD1005HCU601TL

Overview

The WLBD1005HCU601TL is a single-channel ferrite chip bead manufactured by Walsin Technology Corporation. It features a 0402 (1005 metric) surface-mount package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 600 Ohms at a test frequency of 100 MHz with a tolerance of +/-25%. It supports a maximum DC current of 900 mA and has a maximum DC resistance of 230 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high-impedance noise suppression for high-frequency signals in compact designs
• Features flexible soft terminals to accommodate PCB mechanical stress
• Utilizes shielded construction to minimize electromagnetic interference

Applications

• High-speed data line filtering
• Power supply noise attenuation
• RF circuit signal conditioning

Procurement Notes

Verify the specific suffix 'TL' against official Walsin documentation to confirm tape and reel packaging specifications. Ensure the requested quantity aligns with standard manufacturing pack sizes. Cross-reference the impedance value and current rating with system requirements to prevent thermal issues during operation. Confirm RoHS compliance status through the latest manufacturer datasheet before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a 0402 footprint for noise filtering applications. Consider the 900 mA current rating to ensure the bead does not saturate under peak load conditions. Evaluate the 600 Ohm impedance profile against the target noise frequency spectrum to verify effective attenuation. Compare the 230 mOhms DCR against power loss tolerances in the specific circuit path.

Part Context

This part belongs to the WLBD series of ferrite beads from Walsin Technology Corporation. The series offers various impedance values and current ratings within standardized SMD packages. The 1005HC designation indicates a specific high-current variant within the 0402 form factor family, designed for dense PCB layouts requiring robust EMI suppression capabilities.

Replacement Considerations

Direct substitutes include other 0402 ferrite beads with 600 Ohms impedance and similar current ratings. Verify terminal compatibility and thermal characteristics when replacing with components from different manufacturers.
