WLBD1608K2U102TP

Overview

The WLBD1608K2U102TP is a single-channel ferrite chip bead manufactured by Walsin Technology Corporation. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 30 Ohms at a test frequency of 100 MHz with a tolerance of +/-25%. It supports a maximum DC current rating of 1.3 A and has a maximum DC resistance of 0.08 Ohms. The device operates within a temperature range of -55°C to +125°C and utilizes flexible soft terminals for SMD/SMT mounting.

Feature Summary

• Provides electromagnetic interference suppression through high-impedance characteristics at specific frequencies
• Utilizes a shielded multilayer ferrite structure for effective noise attenuation
• Designed for surface-mount technology with flexible terminal construction

Applications

• Power supply line filtering in portable electronic devices
• Signal integrity management in high-speed digital circuits
• Noise suppression on data lines within compact consumer electronics

Procurement Notes

Verify the exact package code against official datasheets, as naming conventions may vary between distributors. Confirm RoHS compliance status directly with the manufacturer or authorized suppliers before integration. Ensure storage conditions align with moisture sensitivity levels specified in the handling guidelines to maintain component reliability during assembly processes.

Selection Notes

Select this component when space constraints require a 0402 footprint while maintaining significant current handling capabilities. Evaluate the 30 Ohm impedance profile against target noise frequencies to ensure adequate attenuation. Compare the 1.3 A current rating against peak circuit loads to prevent saturation. Consider the low DC resistance to minimize voltage drop and power loss in sensitive power rails.

Part Context

This part belongs to Walsin's WLBD series of ferrite beads, designed for general-purpose EMI suppression. The series offers various impedance values and current ratings across multiple standard package sizes. The WLBD1608K2U102TP specifically addresses applications requiring compact noise filtering with moderate impedance characteristics in small form-factor designs.

Replacement Considerations
