WLBD1608HCU300TH

Overview

The WLBD1608HCU300TH is a shielded 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 1.3 A and has a maximum DC resistance of 40 mOhms. The device operates within a temperature range of -55°C to +125°C and utilizes flexible SMD/SMT terminations.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Flexible soft terminations enhance solder joint reliability during thermal cycling
• High current handling capability suitable for power line filtering applications

Applications

• Power supply output filtering
• DC-DC converter noise suppression
• Signal integrity protection in high-current digital circuits

Procurement Notes

Verify the specific suffix TH against the manufacturer's official datasheet to confirm packaging configuration and terminal finish specifications. Ensure the ordered part matches the required 1.3 A current rating and 30 Ohm impedance profile for the target circuit design. Cross-reference the RoHS compliance status with the latest regulatory documentation provided by Walsin Technology Corporation prior to final procurement decisions.

Selection Notes

Select this component when a compact 0603 footprint is required for high-current signal lines. The 1.3 A rating distinguishes it from lower-current variants in the same impedance family. Consider the 40 mOhms DC resistance impact on voltage drop in low-voltage power rails. The wide operating temperature range supports deployment in demanding industrial or automotive environments where thermal stability is critical for consistent noise attenuation performance.

Part Context

This model belongs to the WLBD series of shielded ferrite beads from Walsin Technology Corporation. The series offers various impedances and current ratings across multiple standard package sizes. The HC designation typically indicates a high-current variant within the product line, designed to handle significant DC bias while maintaining effective high-frequency noise absorption characteristics for modern electronic systems.

Replacement Considerations

WLBD1608HCU300TL is a comparable variant within the same series offering identical electrical parameters but potentially different packaging options.
