AS04004PO-2-WR-R

Overview

The AS04004PO-2-WR-R is a miniature electromagnetic speaker manufactured by PUI Audio, Inc. It features a rectangular frame with an oval cone design and operates at a nominal impedance of 4 Ohms. The device has a power rating of 3 Watts and delivers a sound pressure level of 82 dBA. Its frequency response spans from 200 Hz to 20 kHz, with a resonant frequency of 420 Hz. Physical dimensions are approximately 40 mm in length, 28.5 mm in width, and 11.7 mm in height. It utilizes Neodymium Iron Boron magnets and treated paper cones, with solder lug terminals for board mounting.

Feature Summary

• Rectangular frame construction with an oval-shaped acoustic cone
• Wide frequency response capability extending up to 20 kHz
• High-strength Neodymium Iron Boron magnetic system
• Solder lug termination style for direct circuit board integration

Applications

• Automotive audio systems
• General purpose electronic devices
• Consumer electronics enclosures
• Industrial control panels

Procurement Notes

Verify the specific suffix '2-WR-R' against official PUI Audio documentation to confirm the exact power rating and terminal configuration. Ensure the operating temperature range of -40°C to +80°C aligns with the target environment. Confirm that the 4-Ohm impedance matches the amplifier output requirements. Check RoHS compliance status if required by regional regulations. Validate physical clearance for the 40x28.5x11.7 mm form factor during mechanical design.

Selection Notes

Select this component when a compact rectangular speaker with broad frequency response is required. The 3W power handling suits moderate volume applications. The 4-Ohm impedance is standard for many low-voltage audio circuits. Consider the solder lug mounting method for assembly processes. Evaluate the 82 dBA sensitivity against amplifier drive capabilities. The neodymium magnet provides high efficiency in a small package.

Part Context

This model belongs to the AS series of miniature speakers from PUI Audio, Inc., a manufacturer specializing in audio components since 1973. The company produces various transducers including piezo benders and sirens. This specific unit represents their electromagnetic speaker line designed for general-purpose audio reproduction in compact electronic assemblies.

Replacement Considerations

Cross-reference with AS04004PO-WR-R or AS04004PO-2-LW152-WR-R for similar form factors. Verify dimensional compatibility and electrical parameters before substitution. Ensure the replacement maintains the 4-Ohm impedance and adequate power handling. Confirm terminal type matches existing PCB layout.
