AS01508MO-SP11-LW25-R

Overview

The AS01508MO-SP11-LW25-R is an electromagnetic speaker transducer manufactured by PUI Audio, Inc. It features a rectangular form factor with dimensions of 15mm x 11mm and a height of 3.9mm. The unit operates within a frequency range of 600 Hz to 20 kHz, with a self-resonant frequency of 600 Hz. It has an impedance of 8 ohms and a nominal power rating of 700 mW. The device delivers a sound pressure level of 89 dB at 2V/10cm. It utilizes surface mount technology for PCB integration and functions within a temperature range of -20°C to +60°C.

Feature Summary

• Rectangular surface-mount design for compact electronic assemblies
• Electromagnetic transduction using neodymium magnet structure
• Optimized frequency response for voice and general audio applications

Applications

• Consumer electronics requiring small form-factor speakers
• Industrial control panels with limited space
• Medical devices needing reliable audio output

Procurement Notes

Verify the specific suffix and revision code against the manufacturer's current datasheet before ordering, as component specifications may evolve. Confirm that the surface-mount footprint matches your PCB layout exactly. Ensure thermal and mechanical constraints align with the specified operating temperature range of -20°C to +60°C. Check for any RoHS compliance documentation if required for your region. Validate availability status directly with authorized distributors.

Selection Notes

Select this component when a rectangular SMD speaker is required for tight spatial constraints. Compare the 89 dB SPL efficiency against alternatives if higher volume is needed. Consider the 8-ohm impedance for amplifier matching. Evaluate the 700 mW power handling against the expected signal levels. Ensure the 600 Hz lower frequency limit meets the application's bass requirements.

Part Context

This model belongs to PUI Audio's series of miniature electromagnetic speakers designed for surface-mount assembly. It represents a specialized variant optimized for rectangular mounting areas, differing from standard circular drivers. The product line focuses on providing reliable audio transduction in portable and embedded systems where board space is at a premium.

Replacement Considerations

AS01508AO-LW25-R is listed as a direct substitute option in distributor records, though it is marked obsolete. Verify electrical compatibility and physical footprint alignment before substitution. No other official cross-references are confirmed in public data.
