AS03604AR

Overview

The AS03604AR is a general-purpose electromagnetic speaker manufactured by PUI Audio, Inc. It features a 36 mm diameter round frame with a 4 Ohm impedance and a rated power of 3 W. The unit delivers an efficiency of 88 dBA at 1W/1m and operates within a frequency range of 180 Hz to 20 kHz, with a self-resonant frequency of 180 Hz. Designed for compact applications requiring robust low-frequency response and low total harmonic distortion, it utilizes frame mounting and solder eyelet termination.

Feature Summary

• Designed for robust low-frequency response in compact designs
• Low total harmonic distortion characteristics
• General-purpose electromagnetic transducer construction

Applications

• Compact audio devices requiring low THD
• Applications needing robust low-frequency performance
• General-purpose sound output systems

Procurement Notes

Verify the specific datasheet version for the AS03604AR to confirm exact mechanical dimensions and electrical tolerances before integration. Ensure that the 4 Ohm impedance and 3 W power rating align with the driving circuit capabilities. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor channels prior to final procurement decisions.

Selection Notes

Select this component when a compact form factor is required alongside strong low-frequency reproduction capabilities. The 4 Ohm impedance suits standard low-voltage audio drivers, while the 3 W rating provides adequate power handling for general signaling or voice applications. Consider the 180 Hz self-resonant frequency to ensure compatibility with the target signal bandwidth requirements.

Part Context

This model belongs to the AS series of speakers from PUI Audio, Inc., which specializes in audio components for industrial, medical, and consumer electronics. The AS03604AR represents a general-purpose solution focusing on balanced performance metrics rather than extreme sensitivity or high-power output, fitting into the broader portfolio of board and frame-mountable acoustic transducers.

Replacement Considerations

Direct substitutes must match the 36 mm diameter, 4 Ohm impedance, and 3 W power rating. Verify that alternative models maintain similar low-frequency response characteristics and physical mounting hole patterns to ensure mechanical compatibility without redesigning the enclosure.
