WLBD4516K2U151PP

Overview

The WLBD4516K2U151PP is a single-channel ferrite chip bead manufactured by Walsin Technology Corporation. It features an 1806 (4516 metric) surface-mount package with dimensions of 4.5 mm length, 1.6 mm width, and 1.6 mm height. The component provides an impedance of 150 Ohms at a test frequency of 100 MHz with a tolerance of +/-25%. It supports a maximum DC current of 800 mA and has a maximum DC resistance of 300 mOhms. The device operates within a temperature range of -55°C to +125°C and utilizes flexible SMD/SMT terminations.

Feature Summary

• Provides electromagnetic interference suppression through high-impedance characteristics in the 1806 surface-mount form factor.
• Features flexible soft terminations designed to enhance reliability during soldering processes on printed circuit boards.
• Constructed as a shielded single-element component for effective noise filtering in compact electronic assemblies.

Applications

• Electromagnetic interference suppression in portable consumer electronics
• Noise filtering in mobile communication devices
• Signal integrity management in computer peripheral interfaces

Procurement Notes

Verify the specific manufacturer part number WLBD4516K2U151PP against official Walsin documentation to confirm impedance values and package dimensions. Ensure compatibility with automated pick-and-place equipment due to the 1806 case size. Confirm RoHS compliance status through the manufacturer's latest datasheet before integration into regulated products.

Selection Notes

Select this component when a 150 Ohm impedance at 100 MHz is required within a 1806 footprint. Consider the 800 mA current rating for power line applications. Evaluate the 300 mOhms DC resistance for voltage drop constraints. Compare thermal performance requirements against the -55°C to +125°C operating range.

Part Context

This ferrite bead belongs to Walsin's WLBD series of passive components. The series offers various impedance values and package sizes for EMI suppression. The WLBD4516K2U151PP specifically addresses needs for moderate current handling in space-constrained designs using standard surface-mount technology assembly methods.
