Procurement Notes
Verify the specific electrical parameters against the manufacturer's current datasheet before integration. Confirm that the 4 Ohm impedance and 0.5 W power rating align with the target circuit design requirements. Ensure the SMD package dimensions are compatible with the printed circuit board layout and manufacturing capabilities.
Selection Notes
Select this component when a low-profile, square-shaped speaker is required for surface mount technology. The 4 Ohm impedance suits standard low-voltage audio circuits. Consider the 87 dBA sensitivity for applications requiring moderate acoustic output without excessive power consumption. Verify thermal limits during operation.
