Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturing revisions may occur. Confirm that the RoHS3 compliance status matches your regulatory requirements. Ensure the board layout accommodates the physical dimensions and mounting style specified in the official documentation. Cross-reference the terminal configuration to guarantee compatibility with your circuit design before finalizing procurement.

Selection Notes

Select this model when a compact footprint is critical for the product design. The 8 Ohm impedance aligns with standard low-voltage audio amplifier outputs. Consider the 94 dBA efficiency for applications requiring clear audibility without excessive power consumption. The rectangular shape allows for efficient use of available internal chassis space compared to round alternatives.

Part Context

This component belongs to PUI Audio's Slim-Line series, which focuses on miniaturized audio solutions. The manufacturer specializes in custom and standard audio components for industrial, medical, and consumer markets.
