AS04004CO-2-R

Overview

The AS04004CO-2-R is a rectangular electromagnetic speaker manufactured by PUI Audio. It features a 4 Ohm impedance and a nominal power rating of 1.5 W. The device delivers an 84 dBA sound pressure level at 1W/500mm. Its frequency response ranges from 200 Hz to 20 kHz, with a self-resonant frequency of 550 Hz. Physical dimensions are 40 mm in length, 28.5 mm in width, and 11.7 mm in height. It utilizes a paper cone and NdFeB magnet, with solder eyelet termination for board mounting.

Feature Summary

• Rectangular form factor with top port design
• Electromagnetic transduction using neodymium iron boron magnet
• Paper cone construction for acoustic output
• Solder eyelet termination for direct board integration

Applications

• General purpose audio output devices
• Consumer electronics enclosures
• Industrial control panels requiring audible alerts
• Portable battery-operated equipment

Procurement Notes

Verify the specific suffix -R against the manufacturer's current datasheet to confirm packaging and compliance status. Ensure the 1.5 W power rating aligns with the thermal management capabilities of the target PCB layout. Confirm that the 4 Ohm impedance matches the driving circuit's output specifications to prevent overload or insufficient volume.

Selection Notes

Select this component when a compact rectangular speaker is required for general audio applications. The 4 Ohm impedance suits low-voltage driving circuits. The 1.5 W rating provides adequate output for short-range communication. Consider the 200 Hz lower frequency limit if deep bass reproduction is not necessary. The top port design may influence enclosure acoustic tuning compared to rear-port alternatives.

Part Context

This part belongs to the AS series of speakers from PUI Audio. It shares the standard 40x28.5 mm footprint common to this family. Variations within the series typically differ in power rating, impedance, or resonance frequency while maintaining similar physical dimensions and mounting styles.

Replacement Considerations

Direct substitutes include other PUI Audio models with identical 40x28.5 mm dimensions and 4 Ohm impedance, such as the AS04004PO-R, provided the power rating and SPL requirements are met. Verify that any replacement maintains the same solder eyelet termination type.
