AS02208MO

Overview

The AS02208MO is an electromagnetic speaker manufactured by PUI Audio, designed for board mount installation. It features an oval shape with dimensions of 22 mm in length and width, and a height of 5.2 mm. The unit operates at an impedance of 8 Ohms with a power rating of 1 W. Key acoustic parameters include a self-resonant frequency of 1.05 kHz and a sensitivity of 90 dBA. The cone material is Mylar, supported by a rare earth magnet. It utilizes solder pad termination and offers an IP65 ingress protection rating. The operating temperature range spans from -25°C to +60°C.

Feature Summary

• Compact oval design suitable for space-constrained handheld and portable devices
• IP65 rated enclosure providing dust tightness and water jet resistance
• Board mount configuration with solder pad terminations for direct PCB integration

Applications

• Handheld electronic devices
• Portable consumer electronics
• Compact audio output modules

Procurement Notes

Verify the specific datasheet version for the AS02208MO to confirm RoHS compliance status and exact dimensional tolerances before finalizing the design. Ensure that the PCB layout accommodates the required solder pad spacing and that the thermal environment remains within the specified -25°C to +60°C operating range during continuous operation.

Selection Notes

Select this component when a compact, high-efficiency sound source is required for small form factor devices. The 1W power handling and 90 dBA sensitivity provide adequate volume for personal audio applications. Consider the IP65 rating if the device requires protection against environmental contaminants or moisture exposure during use.

Part Context

This part belongs to the AS series of speakers from PUI Audio, which focuses on general-purpose audio transducers. The series includes various sizes and power ratings to support different audio requirements in portable electronics. The AS02208MO specifically targets applications needing a balance between physical size and acoustic output performance.

Replacement Considerations

Check for direct substitutes within the PUI Audio AS series that match the 8 Ohm impedance and similar physical footprint. Verify that any replacement maintains the required 1W power rating and compatible mounting style to ensure seamless integration without redesigning the host PCB.
