AS02404PO

Overview

The AS02404PO is a general-purpose electromagnetic speaker manufactured by PUI Audio, Inc. It features a rectangular frame with an oval cone design and board mount installation style. The component has a nominal impedance of 4 Ohms and a power rating of 2 W. Its frequency response ranges from 450 Hz to 20 kHz, with a resonant frequency typically around 650 Hz. The sound pressure level is rated at 78 dBA or 92 dB depending on measurement conditions. Physical dimensions are approximately 24 mm x 12 mm x 4.5 mm. It utilizes solder eyelet terminals for connection.

Feature Summary

• Rectangular frame with oval cone geometry
• General-purpose electromagnetic transducer
• Board mount installation with solder eyelets

Applications

• Consumer electronics audio output
• Industrial control panel indicators
• Appliance status signaling

Procurement Notes

Verify the specific datasheet revision when ordering, as acoustic measurements like SPL may vary between 78 dBA and 92 dB ratings in different documentation versions. Confirm terminal type compatibility with your PCB layout. Ensure operating temperature range requirements align with the specified -25°C to 50°C limit for reliable performance in your target environment.

Selection Notes

Select this model for applications requiring a compact, low-cost audio solution with standard 4 Ohm impedance. It is suitable where moderate sound pressure is sufficient and space constraints fit the 24x12mm footprint. Consider thermal limits if used in enclosed spaces exceeding 50°C ambient temperature.

Part Context

This part belongs to PUI Audio's general-purpose speaker line, designed for cost-effective audio reproduction in mass-produced devices. It complements other rectangular and oval speakers in the portfolio, offering a balance between acoustic performance and physical size for embedded audio systems.

Replacement Considerations

Check mechanical mounting hole patterns and terminal spacing against alternatives. Verify impedance and power handling match circuit design. Acoustic output levels may differ significantly between substitutes.
