AS04004PO-2-LW152-WR-R

Overview

The AS04004PO-2-LW152-WR-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a rectangular shape with board mount installation and solder eyelet termination. The unit has a power rating of 2 W, an impedance of 4 Ohms, and a resonant frequency of 370 Hz. Sound pressure level is rated at 86 dBA. Dimensions are 40 mm in length, 28.4 mm in width, and 13 mm in depth. Operating temperature ranges from -40 C to +80 C. The cone material is paper and the magnet is Neodymium Iron Boron (NdFeB).

Feature Summary

Rectangular form factor with board mount capability.
Paper cone construction for acoustic performance.
Neodymium Iron Boron magnetic system.

Applications

Electronic devices requiring compact audio output.
Industrial equipment with panel access.
Consumer electronics enclosures.

Procurement Notes

Verify the specific suffix -2-LW152-WR-R against official datasheets to confirm lead wire specifications and connector types. Ensure the rectangular dimensions and mounting style match the design constraints. Confirm RoHS compliance status through manufacturer documentation before finalizing procurement.

Selection Notes

Select this component when a rectangular footprint is required within a 40 mm x 28.4 mm area. The 4 Ohm impedance suits low-voltage driver circuits. The wide operating temperature range supports harsh environments. Verify that the paper cone material meets environmental durability requirements for the target application.

Part Context

This part belongs to the AS series of speakers from PUI Audio, Inc., designed for general-purpose audio transduction. The series offers various shapes and impedances to fit diverse enclosure sizes. This specific model utilizes a paper cone and neodymium magnet for efficient sound generation in compact spaces.

Replacement Considerations

Direct substitutes require matching the 40x28.4mm rectangular dimensions, 4 Ohm impedance, and 2W power rating. Check if alternative models offer compatible solder eyelet terminations or require adapter wiring. Verify that replacement units maintain the same operating temperature range and acoustic output levels.
