Procurement Notes

Verify the specific datasheet version for the MLPF-WB-03D3 to ensure compatibility with your target STM32WB package type. Confirm that the integrated impedance matching aligns with your antenna design requirements. Check for any recent revisions in the official STMicroelectronics documentation regarding thermal or electrical specifications before finalizing procurement.

Selection Notes

Select this component when integrating passive RF filtering directly with STM32WB series MCUs. It simplifies design compared to discrete components by offering higher reliability and lower BOM cost. Ensure the application requires operation at 2.4GHz and supports the specified voltage and temperature ranges.

Part Context

This part belongs to the MLPF product line, which integrates passive devices using IPD technology on high-resistivity substrates. These components support high-level system integration for RF modules, reducing thickness and process variation compared to LTCC or discrete solutions.

Replacement Considerations

MLPF-WB-02D3, MLPF-WB-04D3, and MLPF-WB-05D3 are similar variants in the same series. Verify if alternative models offer different impedance matching characteristics suitable for specific STM32WB package configurations.
