WLBD4516HCU600PH

Overview

The WLBD4516HCU600PH is a ferrite chip bead manufactured by Walsin Technology Corporation, designed for high-frequency noise suppression in surface-mount applications. It features an 1806 (4516 metric) package with dimensions of 4.5 mm length, 1.6 mm width, and 1.6 mm height. The component provides an impedance of 60 Ohms at a test frequency of 100 MHz with a tolerance of +/-25%. It supports a maximum DC current rating of 6 A and has a maximum DC resistance of 15 mOhms. The device operates within a temperature range of -55°C to +125°C and utilizes flexible soft terminals for reliable SMD/SMT mounting.

Feature Summary

• Combines high-frequency noise suppression capabilities with the ability to handle high DC currents.
• Features shielded construction to minimize electromagnetic interference effects.
• Utilizes flexible soft terminals to enhance mechanical reliability during soldering processes.

Applications

• High-current power line filtering in electronic circuits
• Noise suppression in compact surface-mount assemblies
• Signal integrity management in high-frequency data lines

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct impedance and current ratings. Confirm RoHS compliance status through certified datasheets prior to integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Ensure storage conditions align with manufacturer specifications to maintain material integrity before assembly.

Selection Notes

Select this component when circuit designs require significant current handling alongside effective high-frequency attenuation. The 1806 package offers a balance between physical footprint and thermal performance. Evaluate the 6A current rating against peak load requirements to prevent saturation. Consider the low DC resistance to minimize voltage drop and power loss in sensitive power paths.

Part Context

This ferrite bead belongs to the WLBD series from Walsin Technology Corporation, which specializes in passive components for modern electronics. The HC designation typically indicates high-current variants within the lineup. These components are engineered for dense PCB layouts where space constraints coexist with stringent EMI/EMC requirements. The series supports various impedance values to suit different filtering needs across consumer and industrial devices.

Replacement Considerations

Direct substitutes must match the 1806 package, 60 Ohm impedance at 100 MHz, and 6A current rating. Verify terminal compatibility and operating temperature ranges. Consult manufacturer cross-reference lists for approved equivalents that maintain identical electrical and mechanical specifications.
