AS02508CO-4-R

Overview

The AS02508CO-4-R is a general-purpose miniature speaker manufactured by PUI Audio, Inc. It features an 8-ohm impedance and a rated input power of 1.0 W, with a maximum power handling capacity of 1.5 W. The device exhibits a self-resonant frequency of 1100 Hz and operates within a frequency range of 600 Hz to 20 kHz. It delivers a sound pressure level (SPL) of 95 dB when tested at 1 W/10 cm. The physical construction includes a top port design and utilizes an NdFeB magnet.

Feature Summary

• Compact oval or rectangular frame design suitable for space-constrained electronic devices
• High efficiency acoustic output with 95 dB sound pressure level rating
• Top port configuration for directed sound projection
• Utilization of Neodymium Iron Boron (NdFeB) magnetic material for performance

Applications

• Miniature consumer electronics requiring compact audio components
• Portable communication devices
• General purpose audio output in small form-factor hardware

Procurement Notes

Verify the specific package orientation and terminal configuration against the mechanical drawing prior to PCB layout finalization. Confirm that the 1.0 W rated power aligns with the target application's thermal management capabilities. Ensure the 8-ohm impedance matches the driving circuit requirements to prevent signal distortion or amplifier strain during operation.

Selection Notes

Select this component when a balance between high acoustic efficiency and minimal physical footprint is required. The 95 dB SPL rating indicates suitability for applications needing clear audio without excessive power consumption. Consider the 600 Hz to 20 kHz frequency response for voice and mid-range audio reproduction rather than full-range music fidelity.

Part Context

This model belongs to PUI Audio's series of miniature speakers designed for integration into compact electronic assemblies. It represents a standard general-purpose solution offering reliable acoustic performance within a small envelope. The product line focuses on providing cost-effective audio transducers for mass-market consumer devices where size and weight are critical constraints.

Replacement Considerations

Cross-reference mechanical dimensions and mounting hole patterns before substituting. Verify that alternative parts maintain the 8-ohm impedance and similar SPL ratings to ensure consistent system performance. Check for availability of equivalent top-port configurations if directional sound is required.
