WLBD3216HCU500PH

Overview

The WLBD3216HCU500PH is a shielded ferrite chip bead manufactured by Walsin Technology Corporation, designed for surface-mount technology applications. It features a 1206 (3216 metric) package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height. The component provides an impedance of 50 Ohms at a test frequency of 100 MHz with a tolerance of +/-25%. It supports a maximum DC current 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.

Feature Summary

• Integrated shielding design to minimize electromagnetic interference
• Flexible soft terminal construction for enhanced solder joint reliability
• High current handling capability suitable for power line filtering

Applications

• Power line noise suppression in electronic circuits
• Electromagnetic interference filtering for high-current paths
• Signal integrity protection in compact surface-mount assemblies

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct impedance and tolerance specifications. Confirm RoHS compliance status through the latest environmental declaration files provided by Walsin. Cross-reference the part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a 1206 footprint is required for high-current noise suppression. Ensure the circuit design accommodates the 6 A maximum DC current rating without exceeding thermal limits. Verify that the 50 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum. Consider the flexible terminal type if board flexing or mechanical stress is a concern during assembly.

Part Context

This ferrite bead belongs to the WLBD series from Walsin Technology Corporation, which specializes in passive components. The HC designation typically indicates a high-current variant within the product family. Similar parts in the series include different impedance values and package sizes, such as the WLBD3225HCU600PH, allowing designers to scale current capacity and physical dimensions based on specific board layout constraints.

Replacement Considerations

Direct substitutes must match the 1206 package, 50 Ohm impedance, and 6 A current rating. Verify compatibility with flexible terminal requirements. No alternative part numbers are explicitly confirmed in the provided source data.
