AS02708CO-WR

Overview

The AS02708CO-WR-R is a water-resistant cone speaker manufactured by PUI Audio. It features a round shape with dimensions of 27 mm in length and width, and 6.6 mm in height. The unit has an impedance of 4 Ohms and a power rating of 1 W. It delivers a sound pressure level of 80 dBA at a frequency of 750 Hz. The self-resonant frequency is 350 Hz. It utilizes a Neodymium Iron Boron magnet and a cloth cone. Termination is via solder eyelets for board mounting. Operating temperatures range from -20 C to +60 C.

Feature Summary

• Water-resistant construction suitable for protected environments
• Compact square form factor with board mount installation
• High-efficiency electromagnetic design using neodymium magnets

Applications

• Consumer electronics requiring compact audio output
• Industrial control panels with environmental exposure
• Medical devices needing reliable small-scale transducers

Procurement Notes

Verify the specific suffix (e.g., -WR-R) against official datasheets to confirm termination type and packaging details. Ensure the 4 Ohm impedance matches the amplifier output requirements. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement specifications.

Selection Notes

Select this component when a low-profile, water-resistant speaker is required for board-mounted applications. The 1 W power handling and 4 Ohm impedance define the driving circuit constraints. Consider the 27 mm x 27 mm footprint for enclosure space limitations. Evaluate the 80 dBA sensitivity against acoustic environment noise levels.

Part Context

This part belongs to the AS series of speakers from PUI Audio, designed for general-purpose audio transduction. The series includes various shapes and sizes, with this model specifically offering water resistance and a compact square profile. It serves as a standard solution for embedded audio systems where size and durability are prioritized over high-fidelity reproduction.

Replacement Considerations

Check for direct substitutes within the AS series that match the 27 mm dimension and 4 Ohm impedance. Verify if alternative models offer compatible solder eyelet terminations. Ensure any replacement maintains the same operating temperature range and water-resistant classification.
