AS04004PO-2-LWC102-2-R

Overview

The AS04004PO-2-LWC102-2-R is a rectangular electromagnetic speaker manufactured by PUI Audio, Inc. It features a 4 Ohm impedance and a power rating of 3 Watts. The device operates with a self-resonant frequency of 450 Hz and an efficiency of 82 dBA. Its physical dimensions are 40 mm in length, 28.5 mm in width, and 11.7 mm in height. The unit utilizes a paper cone and Neodymium Iron Boron magnet material. Termination is provided via wire leads.

Feature Summary

• Rectangular form factor designed for board mounting applications
• Utilizes Neodymium Iron Boron magnetic structure for performance
• Equipped with wire lead termination for circuit integration

Applications

• General purpose audio output
• Embedded systems requiring compact speakers
• Consumer electronics devices

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct termination type and acoustic parameters. Confirm RoHS compliance status through manufacturer documentation prior to procurement. Ensure mechanical fitment matches the 40mm x 28.5mm footprint requirements of the target design.

Selection Notes

Select this component when a rectangular speaker with wire leads is required instead of solder eyelets or pads. The 4 Ohm impedance suits standard low-voltage driver circuits. The 3W power handling provides adequate output for general indication or voice applications within the specified frequency range.

Part Context

This model belongs to the AS series of speakers from PUI Audio, Inc., which specializes in audio components for industrial and consumer markets. The series includes various shapes and impedances. This specific variant distinguishes itself through its rectangular geometry and wire lead termination style compared to other models in the lineup.

Replacement Considerations

Direct substitutes must match the 4 Ohm impedance, 3W power rating, and rectangular dimensions. Verify that replacement units also feature wire lead terminations to maintain compatibility with existing harnesses or PCB layouts without modification.
