WLBD3216HCU121PH

Overview

The WLBD3216HCU121PH is a single-element ferrite chip bead manufactured by Walsin Technology Corporation. It features a 1206 (3216 metric) surface-mount package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height. The component provides an impedance of 120 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 for SMD/SMT mounting.

Feature Summary

• High current handling capability up to 6 A with low DC resistance
• Shielded construction for effective electromagnetic interference suppression
• Flexible soft terminal design suitable for surface mount technology

Applications

• Power line filtering in electronic circuits
• Electromagnetic interference suppression in high-current applications
• Signal integrity management in compact PCB designs

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct impedance and current ratings. Confirm RoHS compliance status through the specific datasheet provided by Walsin. Cross-reference the Mouser or distributor catalog numbers to validate packaging options such as cut tape or reel availability before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring significant current capacity alongside noise filtering. The 1206 footprint offers a balance between thermal performance and space constraints. Ensure the operating environment stays within the specified -55°C to +125°C range. Compare the 120 Ohm impedance at 100 MHz against target noise frequencies to confirm adequate attenuation characteristics for the specific application requirements.

Part Context

This ferrite bead belongs to the WLBD series from Walsin Technology Corporation, designed for surface-mount applications. The HC designation typically indicates high-current variants within the product line. It shares the standard 1206 metric footprint with other components in the family but differs in electrical specifications such as impedance and current rating compared to lower-current models.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative ferrite beads based on matching impedance curves, current ratings, and physical dimensions before substitution.
