WLBD1005HCU100TH

Overview

The WLBD1005HCU100TH is a shielded ferrite chip bead manufactured by Walsin Technology Corporation, designed for surface mount applications. It features a 0402 (1005 metric) package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 10 Ohms at a test frequency of 100 MHz, with a tolerance of +/-25%. It supports a maximum DC current of 2 A and has a maximum DC resistance of 90 mOhms. The device operates within a temperature range of -55°C to +125°C and utilizes flexible soft terminals.

Feature Summary

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

Applications

• Power line noise suppression in compact electronic devices
• EMI filtering for high-density surface mount circuits
• Signal integrity protection in mobile communication hardware

Procurement Notes

Verify the manufacturer part number WLBD1005HCU100TH against official Walsin documentation to confirm specifications. Ensure compatibility with 0402 footprint requirements and check RoHS compliance status via the provided datasheet. Confirm that the 2 A current rating and 10 Ohm impedance meet circuit design constraints before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require effective EMI suppression on power lines. The 0402 package offers a balance between size and current capacity compared to smaller footprints. Consider the 90 mOhms DC resistance impact on voltage drop and the 2 A rating against peak load currents. Verify operating temperature limits align with environmental conditions.

Part Context

This ferrite bead belongs to Walsin's WLBD series of shielded chip beads. The series includes various impedances and packages tailored for different filtering needs. The HC suffix typically denotes specific current handling characteristics within the product family. This model represents a standard solution for low-impedance power rail noise reduction.

Replacement Considerations
