WLBD3216K2U601PP

Overview

The WLBD3216K2U601PP is a single-channel ferrite chip bead manufactured by Walsin Technology Corporation. It features a 1206 (3216 metric) surface-mount package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height. The component provides an impedance of 600 Ohms at a test frequency of 100 MHz with a tolerance of +/-25%. It supports a maximum DC current of 1 A and has a maximum DC resistance of 80 mOhms. The device operates within a temperature range of -55°C to +125°C and utilizes flexible soft terminals for SMD/SMT mounting.

Feature Summary

• Shielded construction designed to minimize electromagnetic interference
• Flexible soft terminal technology for enhanced solder joint reliability
• High stability characteristics under varying temperature and humidity conditions

Applications

• Noise suppression in high-speed digital signal lines
• Power supply filtering for integrated circuits
• EMI reduction in portable electronic devices

Procurement Notes

Verify the specific suffix 'PP' against official Walsin documentation to confirm packaging configuration and material compliance status. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design. Cross-reference the RoHS status details provided in the manufacturer's datasheet to meet regulatory requirements for the intended market.

Selection Notes

Select this component when a 600 Ohm impedance at 100 MHz is required for noise attenuation in space-constrained designs. The 1206 footprint allows for standard reflow soldering processes. Consider the 1 A current rating to ensure the component does not saturate or overheat during normal operation. The shielded type offers superior performance compared to unshielded alternatives in dense PCB layouts.

Part Context

This part belongs to the WLBD series of ferrite beads from Walsin Technology Corporation. The series includes various impedance values and current ratings within the same 3216 metric package family. The 'K2' designation typically indicates specific magnetic material properties optimized for high-frequency applications. This component is part of Walsin's broader portfolio of passive components aimed at global electronics manufacturing.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 600 Ohm impedance, and 1 A current rating. Verify that alternative manufacturers offer compatible shielding and terminal flexibility. Check for equivalent thermal performance and impedance frequency characteristics to ensure circuit functionality remains unchanged.
