AS01508MO-SC11-R

Overview

The AS01508MO-SC11-R is a miniature electromagnetic receiver speaker manufactured by PUI Audio, Inc. It features an 8-ohm impedance and a rated power of 700 mW (0.7 W). The frequency response ranges from 600 Hz to 20 kHz, with a self-resonant frequency of approximately 600 Hz. The acoustic output is specified at 89 dB SPL. Physically, the unit measures 15 mm in width, 11 mm in length, and 4.7 mm in height, utilizing a top-port design for sound projection.

Feature Summary

• Compact rectangular form factor designed for space-constrained mobile applications
• Electromagnetic transducer technology using magnetic drive mechanism
• Top-port acoustic configuration for directed sound output
• PCB mount installation via solder pin termination

Applications

• Smartwatches and wearable devices
• Pendants and personal audio accessories
• Wi-Fi enabled IoT communication modules
• Miniature consumer electronics requiring high-fidelity voice reproduction

Procurement Notes

Verify exact specifications against the official product datasheet prior to integration. Confirm that the rectangular package dimensions and top-port orientation align with the mechanical enclosure constraints. Ensure the 8-ohm impedance matches the amplifier output requirements. Check for any specific handling precautions related to the miniature size and soldering process during assembly.

Selection Notes

Select this component when a rectangular footprint is required instead of circular alternatives. The 600 Hz to 20 kHz range suits voice-centric applications rather than full-range music. Consider the 700 mW power rating for low-volume portable devices. Verify compatibility with PCB mounting methods and ensure sufficient clearance for the top-port exhaust path in the final housing design.

Part Context

This model belongs to PUI Audio's Mobile Series, which targets cutting-edge wearable and portable electronics. Unlike standard circular speakers, this variant offers a rectangular profile to maximize internal space utilization in slim devices. It serves as a specialized acoustic solution for modern smart wearables where traditional round transducers do not fit efficiently within the chassis geometry.

Replacement Considerations

AS01508MR-R is a similar circular alternative but differs in shape and port location. Cross-referencing requires verifying impedance, power handling, and dimensional constraints. No direct pin-compatible substitutes are confirmed in public documentation; mechanical redesign may be necessary if switching to non-rectangular models.
