Overview
The AS04008PR-WR-R is a general-purpose magnetic speaker manufactured by PUI Audio, Inc. It features an 8-ohm impedance and a nominal power handling capacity of 500 mW. The device exhibits a frequency range spanning from 700 Hz to 4.8 kHz, with a self-resonant frequency of 700 Hz. Efficiency is rated at 92 dBA or 94 dBA depending on the specific datasheet source. The physical dimensions are 40mm in diameter with a depth of 6.5mm, utilizing a round bare mount configuration.
Feature Summary
- Round bare mount design suitable for direct integration into enclosures
- Magnetic technology construction for general audio applications
- Paper cone material for standard acoustic performance
Applications
- General purpose audio output devices
- Consumer electronics requiring compact speakers
- Industrial control panels with audio feedback needs
Procurement Notes
Verify the exact impedance specification (4 ohms vs 8 ohms) across different supplier datasheets before finalizing circuit design. Confirm efficiency ratings (92 dBA vs 94 dBA) match system requirements. Ensure the 500 mW power rating aligns with amplifier capabilities to prevent damage. Check package type availability as tray packaging may be specified.
Selection Notes
Select this component when a compact 40mm round speaker is required for low-power applications. Consider the 700 Hz lower frequency limit for voice or alert tones rather than full-range music. Compare against the obsolete AS04008PR-WR model for compatibility. Evaluate thermal management for continuous operation near the 500 mW limit.
Part Context
This part belongs to the AS series of speakers from PUI Audio, Inc. It serves as a replacement or alternative to the discontinued AS04008PR-WR model. The series focuses on cost-effective, general-purpose audio transducers for mass-market electronic products requiring simple mounting solutions.
Replacement Considerations
The AS04008PR-WR is listed as obsolete with AS04008PR-WR-R identified as a direct substitute. Verify mechanical fit and electrical parameters when swapping between these specific part numbers.
