WLBD3216HCU300PH

Overview

The WLBD3216HCU300PH is a single-channel 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 30 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

• Provides electromagnetic interference suppression for power lines through high-current handling capabilities.
• Features shielded construction to minimize external magnetic field interference.
• Utilizes flexible soft terminals to enhance solder joint reliability during surface mount assembly.

Applications

• Power line filtering in electronic circuits
• High-current signal integrity management
• Electromagnetic interference suppression in compact surface-mount designs

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the 1206 package dimensions and terminal type match your PCB footprint requirements. Ensure the 6 A current rating and 30 Ohm impedance specifications align with your circuit design constraints. Check for any recent updates to the datasheet regarding testing frequencies or operational limits.

Selection Notes

Select this component when designing circuits requiring significant current handling alongside moderate high-frequency noise attenuation. The 1206 package offers a balance between physical size and thermal/current capacity compared to smaller footprints. Consider the low DC resistance to minimize voltage drop in power paths. Verify that the operating temperature range meets the environmental conditions of the final application.

Part Context

This part belongs to the WLBD series of ferrite beads from Walsin Technology Corporation, specifically engineered for power line applications. The 'HC' designation typically indicates high-current characteristics within the product family. It is distinct from higher-impedance variants like the WLBD3216K2U122PP, which are suited for different filtering profiles.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult Walsin's official cross-reference tools or datasheets for equivalent components with matching impedance, current ratings, and package dimensions.
