ASE04008MS-LWC25-2

Overview

The ASE04008MS-LWC25-2 is an electromagnetic speaker manufactured by PUI Audio, Inc. It features a round diaphragm with a square frame and operates at an impedance of 8 ohms. The component delivers a power rating of 2 watts (with some sources citing 2.5W) and achieves a sensitivity of approximately 94 dBA or 80 dBA depending on measurement conditions. Its frequency response spans from 380 Hz to 20 kHz. Designed for surface mount technology (SMD), it utilizes solder pad termination for PCB integration.

Feature Summary

• Surface mount construction with a round diaphragm housed in a square frame
• Electromagnetic transducer type optimized for printed circuit board mounting
• Broad frequency response capability extending up to 20 kHz

Applications

• General purpose audio output devices
• Consumer electronics requiring compact SMD speakers
• Industrial control panels with limited space

Procurement Notes

Verify the specific sensitivity rating (80 dBA vs 94 dBA) and power handling (2W vs 2.5W) against the official datasheet prior to procurement, as discrepancies exist across distributor listings. Confirm that the SMD termination style matches your PCB footprint design. Ensure compliance with RoHS requirements if mandated by your project specifications.

Selection Notes

Select this component when a low-profile, surface-mountable speaker is required for general audio applications. The square frame design may facilitate easier mounting within constrained rectangular enclosures compared to purely round housings. Verify thermal management capabilities given the operating temperature range and power dissipation characteristics.

Part Context

This part belongs to the AS series of speakers from PUI Audio, which includes various electromagnetic transducers. It shares the 8-ohm impedance characteristic common to many audio drivers in this category but distinguishes itself through its specific SMD form factor and dimensional constraints suitable for modern miniaturized electronic assemblies.

Replacement Considerations

No officially confirmed substitute part numbers are available in the provided documentation. Evaluate other PUI Audio SMD speakers with matching 8-ohm impedance and similar dimensions for potential compatibility.
