WLBD1608HCU221TH

Overview

The WLBD1608HCU221TH is a single-element ferrite chip bead manufactured by Walsin Technology Corporation. It utilizes a shielded design with flexible soft termination end connections to enhance solder joint reliability during surface mount assembly. The component operates within a temperature range of -55°C to +125°C and features a 0603 (1608 metric) package size measuring 1.6 mm in length, 0.8 mm in width, and 0.8 mm in height. At a test frequency of 100 MHz, the impedance is specified at 220 Ohms with a tolerance of ±25%. The maximum DC current rating is 1.3 A, and the maximum DC resistance is 40 mOhms.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling
• Flexible soft termination technology improves mechanical stress resistance
• Single-channel configuration for compact circuit integration

Applications

• High-speed digital signal line filtering
• Power supply noise suppression in portable devices
• EMI reduction in consumer electronics circuits

Procurement Notes

Verify the specific impedance value against official datasheets, as conflicting public records indicate variations between 30 Ohms and 220 Ohms for this part number. Confirm the manufacturer source directly from Walsin documentation rather than distributor summaries. Ensure the package dimensions and termination type match the design requirements before finalizing procurement orders.

Selection Notes

Select this component when high-frequency noise attenuation is required in space-constrained designs. The 0603 footprint allows for dense PCB layouts while maintaining adequate current handling capabilities. The soft termination feature is critical for applications subject to mechanical vibration or thermal cycling stress. Evaluate the 1.3 A current rating against peak load conditions to prevent saturation.

Part Context

This ferrite bead belongs to the WLBD series of high-current components designed for robust performance in demanding environments. The HC designation typically indicates a high-current variant within the product family. Walsin integrates these beads into broader passive component portfolios for industrial and consumer markets.

Replacement Considerations

Cross-reference with other 0603 ferrite beads offering similar impedance and current ratings. Verify that substitute components maintain compatible impedance characteristics at 100 MHz and support the required operating temperature range.
