2823

Overview

The Visaton 2823 is a miniature general-purpose loudspeaker designed for printed circuit board assembly. It features an 8-ohm impedance and a nominal diameter of 23 mm with a depth of 8.6 mm. The unit has a maximum power rating of 0.5 W and a minimum power handling of 0.2 W. Its frequency response ranges from 900 Hz to 16,000 Hz, with a resonant frequency (Fs) of 1740 Hz. The speaker delivers a mean sound pressure level of 73 dB.

Feature Summary

• Miniature form factor suitable for space-constrained PCB mounting
• General-purpose audio reproduction capability
• Through-hole terminal configuration for standard assembly

Applications

• Miniature audio output devices
• Printed circuit board integrated speakers
• General purpose signal indication

Procurement Notes

Verify the specific datasheet version for the Visaton 2823 to confirm mechanical tolerances and soldering temperature limits. Ensure the application environment does not exceed the 0.5W maximum power rating to prevent thermal damage. Confirm that the 8-ohm impedance matches the driving circuit requirements. Check for any specific RoHS compliance documentation if required by the manufacturing process.

Selection Notes

Select this component when a small footprint is critical and high-fidelity audio is not required. The 8-ohm impedance is standard for many low-power driver circuits. Consider the 73 dB efficiency for applications where moderate volume is sufficient without additional amplification. The through-hole design simplifies manual or wave soldering processes compared to surface-mount alternatives.

Part Context

Visaton manufactures specialized acoustic components for industrial and consumer electronics. The 2823 belongs to their line of miniature dynamic speakers. These units are typically used in low-cost electronic devices where size constraints dictate the use of sub-miniature transducers. The brand focuses on reliable, cost-effective audio solutions for mass production environments.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 23mm diameter, 8.6mm depth, 8-ohm impedance, and 0.5W power rating. Verify mechanical fit and electrical parameters before substituting with other miniature speakers.
