AS04004PO-2-LW152-R

Overview

The AS04004PO-2-LW152-R is a rectangular electromagnetic speaker manufactured by PUI Audio. It features a 4-ohm impedance and a 3-watt power rating. The device delivers an 82 dBA sound pressure level at a self-resonant frequency of 420 Hz. Its physical dimensions are 40 mm in length, 28.5 mm in width, and 11.7 mm in height. The cone material is paper, and it utilizes a Neodymium Iron Boron magnet. Operating temperatures range from -40°C to +80°C.

Feature Summary

Rectangular frame design with paper cone for general-purpose audio output
High-strength neodymium iron boron magnetic structure
Solder eyelet termination style for board mounting

Applications

General purpose audio transducers
Consumer electronic devices requiring compact speakers
Industrial control panels with limited space

Procurement Notes

Verify the specific suffix and lead length requirements against your schematic before ordering. Confirm that the solder eyelet termination matches your PCB pad layout. Ensure the operating temperature range meets your environmental specifications. Check RoHS compliance status if required by your manufacturing standards. Validate the acoustic parameters against your system's sensitivity needs.

Selection Notes

Select this component when a low-profile rectangular speaker is required. The 4-ohm impedance suits standard amplifier outputs. The paper cone offers a specific tonal characteristic suitable for voice or simple tones. Consider the 11.7 mm depth constraint during mechanical design. Evaluate the 82 dBA efficiency against your volume requirements.

Part Context

This part belongs to the AS series of miniature speakers from PUI Audio. The series includes various configurations with different lead lengths and power ratings. The AS04004PO-2-LW152-R specifically denotes a 3-watt variant with defined lead wire specifications. It is distinct from the 2-watt AS04004PO-R model.
