WLBD4516HCU720PH

Overview

The WLBD4516HCU720PH is a single-channel ferrite chip bead manufactured by Walsin Technology Corporation. It utilizes an 1806 (4516 metric) surface-mount package with dimensions of 4.5 mm in length, 1.6 mm in width, and 1.3 mm in height. The component provides an impedance of 72 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 6 A and features a low maximum DC resistance of 15 mOhms. The device operates within a temperature range of -55°C to +125°C and employs flexible SMD/SMT terminations.

Feature Summary

• Provides effective high-frequency noise suppression for power lines through ferrite material properties.
• Features shielded construction to minimize electromagnetic interference coupling.
• Utilizes flexible soft terminations to enhance solder joint reliability under mechanical stress.

Applications

• Power line filtering in portable electronic devices
• Noise suppression in automotive electronics systems
• EMI reduction in industrial control equipment

Procurement Notes

Verify the specific suffix PH against official Walsin documentation to confirm packaging details and compliance status. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and availability before procurement.

Selection Notes

Select this component when a compact 1806 footprint is required for high-current applications up to 6 A. The 72 Ohm impedance value is suitable for attenuating specific high-frequency noise bands around 100 MHz. Consider the low DC resistance to minimize voltage drop and power loss in sensitive power distribution networks.

Part Context

This ferrite bead belongs to the WLBD series from Walsin, designed for surface-mount technology integration. The HC designation typically indicates a high-current capability variant within the product family. It serves as a passive component for signal integrity management in modern electronic assemblies requiring robust EMI protection.

Replacement Considerations

Consult Walsin technical resources for direct cross-references. Verify that any substitute maintains the 1806 footprint, 6 A current rating, and 72 Ohm impedance characteristics to ensure circuit compatibility.
