AS04504AS

Overview

The AS04504AS is a general-purpose electromagnetic speaker manufactured by PUI Audio. It features a round shape with a square frame and operates at an impedance of 4 Ohms. The unit has a rated input power of 6W, with a peak power handling capability of 7W. It delivers a sound pressure level of 97 dB and exhibits a self-resonant frequency of 140 Hz. The frequency range extends from 140 Hz to 20 kHz. Physical dimensions include a diameter of 42 mm. It utilizes solder eyelets for termination and supports panel mounting.

Feature Summary

• Designed for robust low-frequency response in compact designs
• Features low total harmonic distortion (THD)
• Constructed with a round diaphragm housed in a square frame

Applications

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

Procurement Notes

Verify the specific electrical parameters against the official PUI Audio datasheet before integration. Confirm that the 4-ohm impedance and 6-watt rating align with your amplifier or driver circuit capabilities. Ensure the physical footprint accommodates the square frame design within your enclosure constraints. Check for any RoHS compliance documentation if required for your manufacturing standards.

Selection Notes

Select this component when a balance of high efficiency and low distortion is required in a small form factor. The 4-ohm impedance suits standard low-voltage audio drivers. Consider the square frame geometry for mounting flexibility compared to purely round speakers. Evaluate the 140 Hz lower frequency limit to ensure it meets the bass requirements of the target application.

Part Context

This model belongs to the PUI Audio AS series of speakers and transducers. It is categorized under general-purpose audio devices. The product line focuses on providing reliable acoustic solutions for various consumer and industrial electronics. The AS04504AS specifically targets applications where space is limited but audio fidelity remains important.

Replacement Considerations

Direct substitutes must match the 4-ohm impedance, 42mm diameter, and square frame configuration. Verify that alternative components maintain similar sensitivity levels around 97 dB to ensure consistent volume output. Check that the replacement supports panel mounting and compatible solder eyelet terminations.
