WLBD1608HCU471TH

Overview

The WLBD1608HCU471TH 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 470 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 1 A and has a maximum DC resistance of 200 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics at specific frequencies.
• Features flexible soft terminations suitable for surface-mount assembly processes.
• Designed as a shielded component to contain magnetic fields.

Applications

• Power line filtering in electronic circuits
• Signal integrity management in high-speed data handling systems
• Electromagnetic interference suppression in compact consumer electronics

Procurement Notes

Verify the exact manufacturer part number against official Walsin documentation to ensure compatibility. Confirm that the 0603 package size and 470 Ohm impedance specifications meet the design requirements. Check for RoHS compliance status if required by the target market regulations. Ensure the operating temperature range aligns with the environmental conditions of the final application.

Selection Notes

Select this component when a 470 Ohm impedance at 100 MHz is required for noise suppression in space-constrained designs. The 1 A current rating must be sufficient for the specific power line application. Consider the 200 mOhm DC resistance impact on voltage drop. The -55°C to +125°C range suits most industrial and commercial environments. Verify footprint compatibility with the PCB layout.

Part Context

This ferrite bead belongs to the WLBD series from Walsin, which utilizes a high-permeability material for effective noise absorption. The HC suffix typically denotes a high-current or specific performance variant within the product line. It is part of a broader family of chip beads available in various impedances and packages, such as the WLBD1608HCU121TH and WLBD1608HCU600TH, offering different impedance levels for diverse filtering needs.

Replacement Considerations

Direct substitutes include other 0603 ferrite beads with 470 Ohm impedance at 100 MHz. Verify current ratings and DC resistance values match or exceed the original specifications. Ensure the replacement component maintains the same termination style and thermal characteristics.
