AS02008MR-5-R

Overview

The AS02008MR-5-R is a general-purpose electromagnetic speaker manufactured by PUI Audio, Inc. It features an 8-ohm impedance and a nominal power rating of 500 mW. The device has a round shape with a 20 mm external diameter and operates within a frequency range of 500 Hz to 10 kHz. Key acoustic specifications include a resonant frequency of 630 Hz and a sound pressure level of 86 dBA. The unit utilizes a top port design and employs solder pad termination for board mounting.

Feature Summary

• Top port configuration for optimized acoustic output
• Electromagnetic driver type using neodymium magnet technology
• Solder pad termination for direct PCB integration

Applications

• General purpose audio signaling
• Electronic device feedback systems
• Consumer electronics audio output

Procurement Notes

Verify the specific datasheet version for the AS02008MR-5-R to confirm exact dimensional tolerances and electrical characteristics. Ensure compatibility with the target circuit's voltage and current requirements relative to the 8-ohm impedance. Confirm that the solder pad termination method aligns with the assembly process used in the final product design.

Selection Notes

Select this component when a compact, round electromagnetic speaker is required for general audio applications. The 500 mW power handling and 8-ohm impedance are standard for low-power consumer electronics. Consider the 20 mm diameter and top port design if space constraints and acoustic directionality fit the enclosure layout.

Part Context

This part belongs to the AS series of speakers from PUI Audio, Inc., which offers various electromagnetic transducers. The AS02008MR-5-R is specifically designed as a general-purpose driver, distinct from specialized high-fidelity or high-power variants within the manufacturer's broader audio device portfolio.

Replacement Considerations

Direct substitutes may include other 20 mm round speakers with 8-ohm impedance and similar power ratings. Verify mechanical dimensions, particularly the 20 mm diameter and height, to ensure fitment. Check for equivalent resonant frequencies and SPL levels to maintain acoustic performance consistency.
