AST-02308MR-R

Overview

The AST-02308MR-R is a miniature electromagnetic speaker manufactured by PUI Audio, Inc. It features an 8 Ohm impedance and a power rating of 100 mW to 200 mW. The unit has a round shape with a 23 mm diameter and operates within a frequency range of 600 Hz to 20 kHz. Key electrical parameters include a resonant frequency of 1.5 kHz and a sound pressure level of 75 dBA. It utilizes Neodymium Iron Boron magnets and supports board mount installation via solder eyelets.

Feature Summary

• Miniature form factor suitable for space-constrained designs
• Electromagnetic transduction using neodymium iron boron magnets
• Board mount configuration with solder eyelet termination

Applications

• General purpose audio output in compact electronics
• Portable consumer devices requiring small speakers
• Industrial control panels with limited space

Procurement Notes

Verify the specific datasheet version for the exact power rating, as sources indicate both 100 mW and 200 mW ratings. Confirm that the solder eyelet termination matches your PCB layout requirements. Ensure the operating temperature range of -20°C to +60°C aligns with your application environment. Cross-reference the manufacturer part number AST-02308MR-R with official PUI Audio documentation to confirm current specifications.

Selection Notes

Select this component when a low-profile, round speaker is required for general audio applications. The 8 Ohm impedance is standard for many driver circuits. Consider the 23 mm diameter constraint during mechanical design. The 75 dBA sensitivity provides adequate volume for close-proximity listening. Verify compatibility with the intended driving voltage and power supply capabilities.

Part Context

This model belongs to the AST series of miniature speakers from PUI Audio. The series typically includes various diameters and impedances. The AST-02308MR-R specifically denotes an 8 Ohm variant with a 23 mm diameter. It is designed for surface or board mounting in modern electronic assemblies where size is a critical factor.

Replacement Considerations

Check for direct substitutes within the PUI Audio AST series with matching 8 Ohm impedance and similar dimensions. Verify that any replacement maintains the 600 Hz to 20 kHz frequency response and comparable sound pressure levels. Ensure the new part supports the same solder eyelet termination style.
