WLBD1608K2U471TP

Overview

The WLBD1608K2U471TP is a single-element 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 1.3 A and has a maximum DC resistance of 400 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high-frequency noise suppression through significant impedance characteristics at 100 MHz.
• Designed for surface-mount assembly using flexible soft terminals suitable for SMD/SMT processes.
• Constructed as a shielded, single-channel element within a compact 0603 footprint.

Applications

• High-speed digital signal line filtering
• Power supply noise attenuation in compact circuits
• EMI suppression in portable electronic devices

Procurement Notes

Verify the specific suffix K2U against official Walsin documentation to confirm impedance and current ratings. Ensure the 0603 package dimensions align with PCB layout constraints. Confirm RoHS compliance status via the manufacturer's latest datasheet before integration into regulated products.

Selection Notes

Select this component when a 470 Ohm impedance at 100 MHz is required within a 0603 footprint. The 1.3 A current rating suits moderate power applications. Compare the 400 mOhms DC resistance against circuit loss requirements. Ensure the operating temperature range meets environmental specifications.

Part Context

This part belongs to the Walsin WLBD series of ferrite beads. The series offers various impedance values and current ratings in standard metric packages. The WLBD1608K2U471TP specifically targets applications needing balanced noise filtering and current handling in space-constrained designs.

Replacement Considerations

Cross-reference with other 0603 ferrite beads offering 470 Ohms at 100 MHz. Verify that substitute parts match the 1.3 A current rating and 400 mOhms DC resistance. Ensure physical dimensions and terminal compatibility are identical for direct replacement.
