AS02708CO-WR-R

Overview

The AS02708CO-WR-R is a water-resistant electromagnetic speaker manufactured by PUI Audio. It features a round cloth cone and neodymium iron boron magnet, designed for board mounting with solder eyelet termination. The unit has an impedance of 4 Ohms and a power rating of 1 W. Key acoustic parameters include a resonant frequency of 350 Hz, a self-resonant frequency of 750 Hz, and a sound pressure level of 80 dBA. Physical dimensions are 27 mm in length and width, with a height of 6.6 mm. It operates within a temperature range of -20°C to +60°C.

Feature Summary

• Water-resistant construction suitable for protected environments
• High-efficiency neodymium magnet assembly
• Durable cloth cone diaphragm design

Applications

• Consumer electronics requiring compact audio output
• Industrial control panels with environmental exposure
• Medical devices needing reliable signal indication

Procurement Notes

Verify the specific impedance requirement against the system design, as this model is rated at 4 Ohms rather than the common 8 Ohms standard found in many other series components. Confirm that the operating environment falls within the specified -20°C to +60°C thermal limits to ensure long-term reliability and performance stability.

Selection Notes

Select this component when a low-profile, square-form-factor speaker is required for tight spatial constraints. The 4 Ohm impedance necessitates checking amplifier compatibility compared to higher impedance alternatives. The water-resistant feature distinguishes it from standard non-protected variants within the same physical footprint family.

Part Context

This part belongs to the AS series of speakers from PUI Audio, which focuses on compact electromagnetic transducers. The 'WR' suffix indicates water resistance, while 'CO' denotes the cloth cone material. It serves as a specialized variant within the broader audio device portfolio, offering specific environmental protection not present in standard models.

Replacement Considerations

AS02708CO-R is the non-water-resistant equivalent with identical electrical and mechanical specifications.
