AS02008MR-R

Overview

The AS02008MR-R is a round electromagnetic speaker manufactured by PUI Audio, designed for board mount applications. It features an 8 Ohm impedance and a power rating of 500 mW. The unit has a diameter of 20 mm and a height of 3 mm, utilizing a Mylar cone and Neodymium Iron Boron magnet. It achieves a sound pressure level of 86 dBA with a resonant frequency of 500 Hz. Operating temperatures range from -20 C to +55 C, and it carries an IP65 rating.

Feature Summary

• IP65 rated enclosure providing protection against dust and low-pressure water jets
• Compact 3 mm height design suitable for space-constrained board mounting
• High efficiency output delivering 86 dBA sound pressure level

Applications

• Portable electronic devices requiring compact audio output
• Industrial control panels needing durable environmental sealing
• Medical equipment requiring reliable electromagnetic transducers

Procurement Notes

Verify the specific suffix configuration matches project requirements before ordering. Confirm mechanical dimensions fit the designated PCB footprint. Ensure operating temperature limits align with the intended environment. Check RoHS compliance documentation for regulatory adherence. Validate that the solder pad termination type suits the assembly process.

Selection Notes

Select this component when a sealed, low-profile speaker is required for harsh environments. The IP65 rating distinguishes it from standard unsealed variants in the series. Consider the 500 mW power handling for signal strength needs. Evaluate the 20 mm diameter constraint against available chassis space.

Part Context

This model belongs to the AS series of electromagnetic speakers from PUI Audio. It shares the 8 Ohm impedance characteristic common across many units in this family. The Mylar cone material offers durability compared to paper alternatives. The Neodymium magnet provides strong magnetic flux in a small volume.

Replacement Considerations

Check for direct substitutes within the AS series that maintain the 20 mm diameter and IP65 rating. Verify that any replacement maintains the 8 Ohm impedance and 500 mW power rating. Ensure the new part supports the same -20 C to +55 C operating temperature range.
