Procurement Notes
Verify the specific datasheet provided by Knowles or authorized distributors to confirm exact electrical parameters and mechanical dimensions. Ensure compatibility with your PCB footprint and thermal requirements. Confirm RoHS compliance status if required for your manufacturing process. Cross-reference the part number CJ-30029-P40 with official manufacturer documentation to avoid substitution errors.
Selection Notes
Select this component when a surface-mount speaker is required for general-purpose audio applications. Consider the solder pad termination style for your assembly process. Verify that the physical dimensions fit within your design constraints. Ensure the audio performance meets the specific needs of the target application before finalizing the selection.
Part Context
This part belongs to the Knowles speakers category, specifically identified as a general-purpose SMD speaker. It is distinct from through-hole or specialized acoustic components. The product line focuses on providing reliable audio transduction solutions for modern electronic manufacturing.
Replacement Considerations
Consult official Knowles documentation for verified substitute part numbers. Do not assume cross-compatibility with other generic SMD speakers without verifying pinout, impedance, and dimensional specifications.
