WLBD1005K2U471TP

Overview

The WLBD1005K2U471TP 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 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 470 Ohms 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 1 Ohm. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high-frequency noise suppression through significant impedance characteristics at 100 MHz.
• Utilizes a shielded design to minimize electromagnetic interference in compact layouts.
• Features flexible soft terminals to enhance solder joint reliability during surface mount assembly.

Applications

• High-speed data line filtering in portable electronic devices
• Power supply noise attenuation in compact circuit boards
• Signal integrity enhancement in RF communication modules

Procurement Notes

Verify the specific suffix 'TP' against official Walsin documentation to confirm packaging details such as tape and reel specifications. Ensure the impedance value of 470 Ohms matches the target noise frequency requirements. Confirm RoHS compliance status directly from the manufacturer's datasheet before integration into regulated products.

Selection Notes

Select this component when space constraints require a 0402 footprint for ferrite beads. Consider the 200 mA current rating to ensure it exceeds the operating current of the protected circuit. Evaluate the 1 Ohm DC resistance to verify it does not cause unacceptable voltage drop in low-voltage applications.

Part Context

This part belongs to the WLBD series of ferrite chip beads from Walsin Technology Corporation. The series offers various impedance values and current ratings within standard industrial footprints. These components are designed for general-purpose EMI suppression in consumer electronics and industrial equipment requiring reliable noise filtering.

Replacement Considerations

WLBD1005K2U471TB is a variant within the same product family. Verify if the 'B' suffix indicates a different packaging type or minor specification change compared to the 'TP' suffix before substitution.
