WLBD4532K2U800PP

Overview

The WLBD4532K2U800PP 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 800 mA and has a maximum DC resistance of 400 mOhms. The device operates within a temperature range of -55°C to +125°C and utilizes flexible SMD/SMT terminals.

Feature Summary

• Shielded construction for effective electromagnetic interference suppression
• Flexible soft terminal design for enhanced solder joint reliability
• Single-channel configuration with one element

Applications

• High-frequency EMI suppression circuits
• Signal line filtering in electronic devices
• Power supply noise reduction applications

Procurement Notes

Verify the specific ordering suffix and packaging format against official Walsin documentation before procurement. Confirm that the requested quantity aligns with available reel or cut-tape options. Ensure compliance with RoHS requirements as specified in the manufacturer's datasheet. Cross-reference the Mouser number 791-WLBD4532K2U800PP with the original part number to prevent substitution errors during acquisition.

Selection Notes

Select this component when an 80 Ohm impedance at 100 MHz is required for noise attenuation. The 800 mA current rating suits moderate power applications. The 1812 footprint allows for standard surface-mount assembly processes. Consider the 400 mOhms DC resistance for voltage drop calculations in series configurations. Verify thermal performance within the -55°C to +125°C operating range for the target environment.

Part Context

This ferrite bead belongs to the WLBD series of passive components produced by Walsin Technology Corporation. It is categorized under ferrites and filters within the broader electronics component market. The product is designed for surface-mount technology integration, supporting automated PCB assembly workflows common in modern consumer and industrial electronics manufacturing.

Replacement Considerations

Consult official Walsin documentation for verified substitute part numbers. Ensure any replacement matches the 80 Ohm impedance, 800 mA current rating, and 1812 package dimensions.
