AS04008PS-4W-WR-R

Overview

The AS04008PS-4W-WR-R is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a rectangular frame design with dimensions of 40 mm in length and 28 mm in width. The unit operates at an impedance of 8 Ohms and has a power rating of 2 W continuous, with a maximum capacity of 4 W. It utilizes a Neodymium magnet and offers a sensitivity of 84 dB (1W/0.5m). The frequency response ranges from 380 Hz to 20 kHz, making it suitable for general-purpose audio applications requiring compact form factors.

Feature Summary

• Rectangular frame construction optimized for space-constrained installations
• High-efficiency Neodymium magnet system for enhanced acoustic output
• Broad frequency response capability extending into high frequencies

Applications

• General purpose audio devices
• Compact consumer electronics enclosures
• Industrial control panels requiring audible feedback

Procurement Notes

Verify the specific suffix WR against official datasheets to confirm terminal configuration and mounting hardware compatibility. Ensure the 2W continuous power rating aligns with the thermal management capabilities of the target application environment. Cross-reference the 84 dB sensitivity specification with system gain requirements to prevent distortion or insufficient volume levels during operation.

Selection Notes

Select this model when a rectangular footprint is required instead of standard circular speakers. The 8 Ohm impedance matches common amplifier outputs without requiring complex matching networks. Consider the 40x28mm physical dimensions to ensure adequate clearance within the housing design. The wide frequency range supports voice and tone reproduction beyond simple beeper functions.

Part Context

This component belongs to the PUI Audio AS series of electromagnetic transducers. It represents a specialized variant within the lineup, distinguished by its rectangular geometry and top-port configuration. The series generally targets OEM designers needing reliable audio solutions in limited spatial envelopes.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate other PUI Audio rectangular models like the AS04008PS-4W-R for dimensional compatibility, but verify terminal types and sensitivity differences carefully.
