AS04016MR-4-LW34

Overview

The AS04016MR-4-LW34 is a round electromagnetic speaker manufactured by PUI Audio, Inc. It features a 16 Ohm impedance and a power rating of 2 W. The device operates within a frequency range of 680 Hz to 10 kHz with a resonance frequency of 680 Hz. It delivers a sound pressure level of 90 dBA when tested at 100 mW/100 mm. The physical dimensions are 40 mm in diameter and 6.5 mm in depth. It utilizes solder lug termination for board mounting.

Feature Summary

• Electromagnetic transducer design utilizing neodymium magnet technology
• Round form factor suitable for bare board integration
• High efficiency acoustic output relative to input power

Applications

• General purpose audio indication
• Consumer electronics feedback systems
• Industrial control panel signaling

Procurement Notes

Verify the specific suffix LW34 against official datasheets to confirm terminal configuration and acoustic tolerances. Ensure compatibility with the target PCB layout regarding solder lug spacing. Confirm RoHS compliance status through current manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component where a 16 Ohm load is required for the amplifier stage. The 680 Hz to 10 kHz response suits voice or tone applications rather than full-range music reproduction. Evaluate the 90 dBA SPL requirement against enclosure acoustics. The 40 mm diameter must fit within the available chassis space.

Part Context

This model belongs to the PUI Audio general-purpose speaker series. It shares the standard 40 mm diameter footprint common in many industrial and consumer devices. The electromagnetic construction distinguishes it from piezoelectric alternatives in the same product line.

Replacement Considerations

AS04016MR-R is a similar 16 Ohm unit but may differ in frequency response and SPL. Verify electrical parameters and mechanical dimensions before substitution.
