AS02204MR-N50-LW40-R

Overview

The AS02204MR-N50-LW40-R is a general-purpose round speaker manufactured by PUI Audio, Inc. It features a 22 mm diameter with a height of 6.7 mm. The device has a nominal impedance of 4 Ohms and a power rating of 2 Watts. It delivers a sound pressure level of 79 dB at 1 kHz and operates within a frequency range of 320 Hz to 20 kHz. The self-resonant frequency is typically 400 Hz. The unit utilizes a bare mount installation style.

Feature Summary

Compact round design suitable for space-constrained applications
General-purpose audio transducer capability
Bare mount configuration for flexible integration

Applications

Consumer electronics audio output
Small appliance signaling
Industrial control panel indicators

Procurement Notes

Verify the specific suffix LW40-R against official datasheets to confirm the 400 Hz self-resonant frequency and 79 dB sensitivity parameters. Ensure the 4 Ohm impedance and 2 Watt power rating match the target circuit requirements. Confirm the 22 mm physical dimensions fit the assembly constraints before ordering.

Selection Notes

Select this component when a compact 22 mm round speaker is required for general audio tasks. The 4 Ohm impedance suits standard low-voltage driver circuits. Consider the 6.7 mm height profile for thin enclosures. Verify that the 320 Hz to 20 kHz frequency response meets the application's acoustic needs.

Part Context

This model belongs to the AS02204MR series of speakers from PUI Audio, Inc. The series offers various configurations for different acoustic and mechanical requirements. The AS02204MR-N50-LW40-R specifically denotes the variant with the LW40-R suffix, indicating its unique resonant and sensitivity characteristics within the product line.

Replacement Considerations

Direct substitutes may include other 22 mm, 4 Ohm, 2 W round speakers from PUI Audio or competitors. Verify compatibility by matching impedance, power handling, and mounting dimensions. Cross-reference datasheets for equivalent frequency response and SPL ratings.
