Speakers Procurement Notes

Verify the specific datasheet version when ordering, as mechanical drawings may indicate slight dimensional variances such as 3.5 mm thickness in some documentation. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, Seltech International, prior to finalizing procurement plans.

Speakers Selection Notes

Select this component for space-constrained designs requiring a rectangular footprint. The 8 Ohm impedance suits standard low-voltage audio circuits. Ensure the application environment accommodates the 900 Hz resonant frequency and that the 70 dB SPL meets the required audibility standards for the target device.

Speakers Part Context

This model belongs to Seltech's line of compact dynamic loudspeakers designed for portable electronics. The CR1511 series emphasizes miniaturization while maintaining functional audio output. It serves as a core transducer component in various consumer and industrial handheld devices where size is a critical constraint.

Speakers Replacement Considerations

Check for exact dimensional compatibility if substituting. Verify that replacement parts match the 8 Ohm impedance and 800 mW power rating. Ensure the new component supports similar frequency response characteristics for consistent audio performance.
