AS04804PS

Overview

The AS04804PS is a general-purpose electromagnetic speaker manufactured by PUI Audio. It features a 48 mm diameter round frame with 27 mm depth and 4 Ohms impedance. The unit supports a 10 W rated input power and 8.0 W continuous dissipation. Its frequency range spans from 150 Hz to 20 kHz, with a free-air resonance at 150 Hz. Sound pressure level is specified at 85 dBA when driven by 1.0 W at a distance of 0.5 meters. Termination is achieved via solder pads.

Feature Summary

• Designed for robust low-frequency response and low total harmonic distortion in compact designs
• Utilizes a 48 mm diameter round frame construction
• Supports high power handling with 10 W rated input capacity

Applications

• General purpose audio output
• Compact electronic enclosures requiring low THD
• Applications demanding robust low-frequency performance

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with PUI Audio or authorized distributors before finalizing procurement. Confirm that the solder pad termination style aligns with your PCB layout requirements. Ensure the thermal management design accommodates the 8.0 W continuous dissipation rating during operation to maintain component reliability.

Selection Notes

Select this model when a 48 mm form factor fits the mechanical constraints. The 4 Ohm impedance requires matching amplifier output stages appropriately. Consider the 150 Hz lower frequency limit; if higher bass extension is needed, alternative models must be evaluated. Verify that the 85 dBA sensitivity meets the required acoustic output levels for the target application environment.

Part Context

This component belongs to the AS series of speakers from PUI Audio. The series includes various sizes and impedances tailored for different audio applications. The AS04804PS specifically targets general-purpose uses where moderate size and high power handling are prioritized over ultra-compact dimensions.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Engineers should consult PUI Audio technical support for direct replacements or cross-reference based on exact electrical and mechanical parameters.
