WLBD1608K2U252TB

Overview

The WLBD1608K2U252TB is a single-element ferrite chip bead manufactured by Walsin Technology Corporation. It utilizes a shielded design with SMD/SMT termination style in a 0603 (1608 metric) package measuring 1.6 mm x 0.8 mm x 0.8 mm. The component provides an impedance of 2.5 kOhms at a test frequency of 100 MHz with a tolerance of +/-25%. It supports a maximum DC current of 200 mA and has a maximum DC resistance of 700 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Shielded construction for effective high-frequency noise suppression
• Flexible soft terminations compatible with standard surface mount processes
• Single-channel configuration optimized for compact circuit layouts

Applications

• High-frequency noise suppression circuits
• Signal integrity management in compact electronic devices
• Power line filtering for sensitive components

Procurement Notes

Verify the specific suffix against official manufacturer documentation, as variations may exist between tape-and-reel and cut-tape packaging formats. Confirm RoHS compliance status through the latest datasheet or environmental declaration provided by Walsin. Ensure the selected variant matches the required impedance tolerance and current rating for the target application before finalizing procurement orders.

Selection Notes

Select this component when a 2.5 kOhm impedance at 100 MHz is required within a 0603 footprint. The 200 mA current rating limits suitability for high-power lines; verify that the load current remains below this threshold to prevent saturation. The shielded design offers advantages in dense PCB layouts where magnetic interference must be minimized compared to unshielded alternatives.

Part Context

This part belongs to the WLBD series of ferrite beads from Walsin Technology Corporation. The series covers various impedance values and current ratings within standard metric packages like 0603 and 1608. These components are designed to suppress electromagnetic interference in digital and analog circuits, providing a passive solution for signal conditioning without active power requirements.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult Walsin's official cross-reference tools or datasheets for equivalent components with matching impedance, current, and package specifications.
