WLBD1608HCU102TH

Overview

The WLBD1608HCU102TH is a single-line 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 1000 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 800 mA and features a maximum DC resistance of 250 mOhms. The device operates within a temperature range of -55°C to +125°C and is RoHS3 compliant.

Feature Summary

• Provides high impedance attenuation for electromagnetic interference suppression in single-channel circuits
• Features flexible soft terminals designed to enhance solder joint reliability during surface mount assembly
• Constructed as a shielded element to minimize external magnetic field interaction

Applications

• High-speed data line filtering in portable electronic devices
• Power supply noise suppression on input/output interfaces
• EMI reduction in compact consumer electronics using 0603 footprints

Procurement Notes

Verify the specific suffix TH against official Walsin documentation to confirm terminal plating and packaging configuration. Ensure the ordered part matches the 1000 Ohm impedance specification at 100 MHz. Confirm RoHS3 compliance status directly with the manufacturer or authorized distributor prior to procurement to meet environmental regulations.

Selection Notes

Select this component when circuit design requires significant noise attenuation at 100 MHz within a constrained 0603 footprint. Evaluate the 800 mA current rating against peak load requirements to prevent saturation. Consider the 250 mOhm DC resistance impact on power efficiency for low-voltage applications.

Part Context

This ferrite bead belongs to the WLBD series of chip beads from Walsin Technology Corporation. The series offers various impedance values in standard metric packages. The HC designation typically indicates a specific material composition optimized for high-frequency performance in compact form factors suitable for modern dense PCB layouts.

Replacement Considerations

Direct substitutes must match the 0603 package, 1000 Ohm impedance at 100 MHz, and similar current handling capabilities. Verify pin compatibility and thermal characteristics before substitution.
