WLBD4532HCU800PH

Overview

The WLBD4532HCU800PH is a shielded ferrite chip bead manufactured by Walsin Technology Corporation. It features an 1812 (4532 metric) surface-mount package with dimensions of 4.5 mm length, 3.2 mm width, and 1.5 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 9 A and has a maximum DC resistance of 10 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 minimizes electromagnetic interference coupling
• High current handling capability suitable for power line applications
• Flexible terminal design enhances solder joint reliability

Applications

• Power line filtering in electronic circuits
• Noise suppression in high-current signal paths
• EMI reduction in portable devices

Procurement Notes

Verify the specific impedance value and current rating against the official Walsin datasheet before integration. Confirm that the 1812 package dimensions align with the PCB footprint requirements. Ensure the operating temperature range meets the environmental conditions of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when high current capacity is required alongside effective noise suppression. The 80 Ohm impedance at 100 MHz targets specific frequency bands for EMI control. The shielded design is preferred for dense layouts where crosstalk must be minimized. Verify that the low DC resistance does not introduce excessive voltage drop in the target circuit path.

Part Context

This ferrite bead belongs to Walsin's WLBD series of passive components designed for signal integrity and power management. The HC suffix typically denotes high-current variants within the product family. As a single-element, one-channel device, it serves as a fundamental building block for filtering applications in consumer electronics and industrial equipment manufactured by Walsin Technology Corporation.

Replacement Considerations

WLBD4532HCU601PH offers higher impedance but lower current handling. WLBD3216HCU800PH provides similar impedance in a smaller 1206 package with reduced current capacity.
