AS04008PO-2-WR-R

Overview

The AS04008PO-2-WR-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a nominal impedance of 8 Ohms and a power rating of 1 W to 2 W. The device operates within a frequency range of 450 Hz to 20 kHz, with a self-resonant frequency of 450 Hz. It delivers a sound pressure level of 84 dBA. The transducer utilizes a Neodymium Iron Boron magnet and a treated paper cone. Physical dimensions include an oval shape with a rectangular frame, measuring approximately 40 mm in length and 28.3 mm in width. The unit employs solder lug terminals for board mounting.

Feature Summary

• Utilizes a neodymium iron boron magnetic structure for efficient audio conversion
• Features a treated paper cone diaphragm for acoustic performance
• Designed for panel or board mounting applications via solder lug connections

Applications

• General purpose audio output devices
• Electronic equipment requiring compact electromagnetic speakers
• Consumer electronics assemblies

Procurement Notes

Verify the specific power rating (1 W vs 2 W) and tolerance specifications against the official manufacturer datasheet prior to procurement. Confirm that the solder lug terminal type matches the target PCB footprint design. Ensure compliance with RoHS requirements as indicated in the product documentation. Cross-reference the exact dimensional tolerances for mechanical integration.

Selection Notes

Select this component when an 8 Ohm impedance and 84 dBA efficiency are required for space-constrained designs. The oval form factor with a rectangular frame facilitates mounting in non-circular enclosures. The treated paper cone offers specific acoustic characteristics distinct from synthetic materials. Verify thermal operating limits align with the intended application environment.
