Procurement Notes

Verify the exact operating voltage and current specifications against the official datasheet before integration, as these parameters can vary significantly between different suffixes or manufacturing batches. Ensure that the mounting hole dimensions match your PCB layout requirements. Confirm the polarity markings if applicable, although piezo buzzers are often non-polarized, checking the manufacturer's documentation is essential for correct installation and optimal performance.

Selection Notes

Select this component based on the required acoustic output level and physical space constraints within the target device. Consider the operating voltage compatibility with the host system's power supply rails. Evaluate the environmental conditions such as temperature range and humidity resistance to ensure reliability in the intended application environment. Compare the mechanical mounting style with available board real estate.
