AST-03008MR-R

Overview

The PUI Audio AS03008MR-R is an electromagnetic speaker with a round shape and board mount installation style. It features solder pad termination and a Mylar cone material. The unit operates within a temperature range of -20°C to +60°C. Key electrical parameters include an impedance of 8 Ohms, a power rating of 500 mW, and a sound pressure level of 82 dBA. The self-resonant frequency is 500 Hz, with a specified frequency response starting at 650 Hz. Physical dimensions are 30 mm in diameter and 4.8 mm in depth.

Feature Summary

• Utilizes Neodymium Iron Boron (NdFeB) magnet material for efficient audio transduction
• Designed for direct board mounting via solder pad connections
• Constructed with a durable Mylar cone for consistent performance

Applications

• General purpose audio output devices
• Embedded electronic assemblies requiring compact speakers
• Consumer electronics internal audio components

Procurement Notes

Verify the exact part number against official manufacturer documentation, as the input model AST-03008MR-R appears to contain a typographical variance compared to the standard AS03008MR-R designation found in public catalogs. Confirm RoHS compliance status and specific packaging quantities directly with the supplier or authorized distributor before finalizing procurement orders to ensure alignment with project requirements.

Selection Notes

Select this component when a low-profile, 8-ohm electromagnetic speaker is required for board-level integration. The 500 mW power handling and 82 dBA sensitivity make it suitable for applications where moderate volume output is sufficient. Ensure the design accommodates the 30 mm diameter footprint and 4.8 mm height constraint while providing adequate thermal management within the specified operating temperature range.

Part Context

This component belongs to the AS series of speakers from PUI Audio, which typically includes various sizes and configurations of electromagnetic transducers. The AS series is characterized by its use of NdFeB magnets and diverse cone materials like Mylar, catering to different acoustic and physical constraints in modern electronic device designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Evaluate other models within the PUI Audio AS series, such as the AS02008MR-R or AS04008PR-R, based on dimensional compatibility and acoustic requirements if a direct replacement is necessary.
