WLBD1608HCU300TL

Overview

The WLBD1608HCU300TL is a single-channel ferrite chip bead manufactured by Walsin Technology Corporation. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 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 5 A and has a maximum DC resistance of 10 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

• Provides electromagnetic interference suppression through high-impedance characteristics at specific frequencies
• Designed for surface-mount technology with flexible soft terminals to accommodate board stress
• Constructed as a shielded single-element component for reliable signal integrity management

Applications

• Power line filtering in electronic circuits
• Signal integrity management in high-speed digital interfaces
• Electromagnetic interference suppression in compact consumer electronics

Procurement Notes

Verify the complete part number including suffixes such as TL, TP, or TB, as these indicate specific packaging configurations like cut tape or reel quantities. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the selected variant matches the required handling method for your assembly process. Cross-reference datasheet specifications against application requirements to validate thermal and electrical performance limits.

Selection Notes

Select this component when a low-impedance path is required for high-current applications while maintaining noise suppression capabilities. The 0603 footprint offers space efficiency for dense PCB layouts. Compare the 5 A current rating against peak load conditions to prevent saturation. Consider the 10 mOhm DC resistance impact on power loss calculations. Evaluate the -55°C to +125°C operating range against environmental constraints.

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 capability within the product family. Similar variants include WLBD1608HCU121TL with higher impedance and WLBD1608K2U300TP with lower current ratings. The series supports various standard footprints including 0402 and 1206 sizes.

Replacement Considerations
