WLBD4516K2U800PP

Overview

The WLBD4516K2U800PP 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 80 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 100 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

• Designed for electromagnetic interference suppression in electronic circuits
• Utilizes shielded construction to manage high-frequency noise
• Features flexible soft terminals compatible with standard surface-mount processes

Applications

• High-frequency noise suppression in digital signal lines
• Electromagnetic interference filtering in portable devices
• Power line noise attenuation in compact electronics

Procurement Notes

Verify the specific manufacturer part number against official Walsin documentation to ensure exact impedance and current ratings match design requirements. Confirm RoHS compliance status through the manufacturer's latest environmental declarations. Validate that the 1806 package footprint aligns with the intended PCB layout and soldering profile specifications.

Selection Notes

Select this component when a low-profile 1806 ferrite bead is required for noise suppression. Ensure the circuit current does not exceed the 800 mA rating to prevent saturation. Consider the 100 mOhm DC resistance impact on voltage drop. Verify that the 80 Ohm impedance at 100 MHz matches the target noise frequency spectrum for effective attenuation.

Part Context

This component belongs to the WLBD series of ferrite beads from Walsin Technology Corporation. The series offers various impedance values and package sizes, including 0603, 1206, and 1812 metrics. The WLBD4516K2U800PP specifically addresses applications requiring moderate current handling and standard EMI filtering in space-constrained designs.

Replacement Considerations

Cross-reference with other Walsin WLBD4516K2U variants for different impedance levels. Verify mechanical compatibility with existing footprints before substituting. Ensure electrical parameters such as DC current rating and impedance tolerance meet or exceed original design specifications.
