WLBD1608HCU301TH

Overview

The WLBD1608HCU301TH is a single-channel ferrite chip bead manufactured by Walsin Technology Corporation. It utilizes 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 300 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 1.5 A and features a maximum DC resistance of 150 mOhms. The device operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Shielded construction to minimize electromagnetic interference
• Flexible soft terminals designed to reduce mechanical stress on the substrate

Applications

• Automotive electronic circuits requiring EMI suppression
• Power line filtering in compact mobile devices
• High-frequency noise attenuation in consumer electronics

Procurement Notes

Verify the specific suffix 'TH' against official manufacturer documentation to confirm tape-and-reel packaging specifications. Ensure the part number matches the exact impedance and current ratings required for your circuit design. Cross-reference the AEC-Q200 certification status directly with Walsin's published datasheets to validate automotive grade compliance before integration.

Selection Notes

Select this component when a 0603 footprint is constrained but higher current handling than standard beads is needed. The 1.5 A rating distinguishes it from lower-current variants in the same series. Consider the 300 Ohm impedance profile for specific high-frequency noise spectra. Verify that the 150 mOhms DC resistance aligns with power loss constraints in the target application path.

Part Context

This part belongs to Walsin's WLBD series of shielded ferrite beads. The 'HC' designation typically indicates a high-current variant within the 1608 package family. It shares physical dimensions with other 0603 components but offers distinct magnetic properties optimized for power line applications. The series emphasizes robustness in automotive and industrial environments through standardized testing protocols.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers must consult Walsin's official cross-reference guides or distributor databases for verified equivalents. Direct replacement requires matching impedance, current rating, and package dimensions precisely.
