Procurement Notes
Verify the specific revision and manufacturing date code against current availability, as component status may change. Confirm mechanical dimensions and mounting requirements match the target enclosure design. Ensure electrical specifications, including impedance and power handling, align with the driving circuit capabilities to prevent damage or performance degradation during operation.
Selection Notes
Select this component when a compact rectangular speaker with top-port functionality is required. Consider the 8-ohm impedance and 600 mW rating for compatibility with standard audio drivers. Evaluate the 75 dB SPL and 96 dB sensitivity metrics against the desired volume levels in the intended application environment.
