AS01508AO-SC-R

Overview

The AS01508AO-SC-R is a general-purpose electromagnetic speaker manufactured by PUI Audio, Inc. It features an 8-ohm impedance and a power rating of 500 mW. The device operates within a frequency range of 500 Hz to 14 kHz with a self-resonant frequency of 500 Hz. It delivers a sound pressure level of 84 dBA. The unit utilizes a top-port design and employs neodymium magnet technology. Physical dimensions include a diameter of 15 mm, with a maximum height of approximately 4.4 mm. The cone material is polyester (PET), and it supports board mount installation via solder pads.

Feature Summary

• Top-port acoustic design for directed sound output
• Neodymium magnetic structure for efficient performance
• Polyester cone material for durability
• General-purpose electromagnetic transducer type

Applications

• Consumer electronics audio output
• Portable device speakers
• General purpose alarm systems
• Small form-factor audio modules

Procurement Notes

Verify the specific suffix and revision code against the manufacturer's current datasheet to ensure compatibility with your design requirements. Confirm that the 500 mW power rating aligns with your system's drive capabilities. Check for RoHS compliance status if required by your regional regulations. Ensure the board mount pad layout matches your PCB footprint specifications before finalizing procurement.

Selection Notes

Select this component when a compact, low-power speaker is required for general audio applications. The 8-ohm impedance is standard for many driver circuits. Consider the 84 dBA sensitivity for volume requirements in small enclosures. The top-port configuration may influence enclosure design compared to rear-port alternatives. Verify thermal limits if operating near the maximum power rating.

Part Context

This model belongs to PUI Audio's line of slim-line micro speakers. It is part of a family of board-mount transducers designed for space-constrained devices. Similar models in the series may vary in power handling, sensitivity, or physical depth. The AS01508AO-SC-R represents a specific configuration within this broader product category, optimized for cost-effective general-purpose use.

Replacement Considerations

Direct substitutes must match the 8-ohm impedance, 500 mW rating, and 15 mm diameter. Models like AS01508MR-R share similar dimensions but differ in power rating and porting. Verify mechanical fit and electrical parameters before substitution. No other specific replacement part numbers are confirmed in public documentation.
