AS02204MR-N50-R

Overview

The AS02204MR-N50-R is a round electromagnetic speaker manufactured by PUI Audio, Inc. It features a 22mm external diameter and operates within a frequency range of 200 Hz to 20 kHz. The unit has an impedance of 4 Ohms and a power rating of 2.5 W. It delivers a sound pressure level of 79 dBA with a self-resonant frequency of 300 Hz. The physical dimensions are 22mm in diameter and 6.7mm in height, utilizing bare mount installation.

Feature Summary

• Round shape design for compact integration
• Electromagnetic driver technology
• Bare mount installation style

Applications

• General purpose audio output devices
• Consumer electronics enclosures
• Industrial control panels

Procurement Notes

Verify the specific suffix N50-R against official datasheets to confirm impedance and power ratings match system requirements. Ensure mechanical clearance accommodates the 22mm diameter and 6.7mm height. Confirm solder eyelet or bare mount compatibility with the target PCB layout before finalizing orders.

Selection Notes

Select this component when a low-profile, general-purpose electromagnetic speaker is required. The 4 Ohm impedance suits standard amplifier outputs. The 22mm form factor allows for tight spatial constraints. Verify that the 79 dBA sensitivity meets the acoustic performance needs of the application environment.

Part Context

This part belongs to the AS series of speakers from PUI Audio, Inc., designed for general-purpose audio applications. The series offers various sizes and impedances to accommodate different enclosure sizes and drive circuits. The AS02204MR-N50-R specifically targets applications requiring a balance between size and acoustic output.

Replacement Considerations

Direct substitutes must match the 22mm diameter, 4 Ohm impedance, and similar resonant frequency characteristics. Cross-reference with other PUI Audio models in the AS series for dimensional compatibility. Ensure any replacement maintains the same mounting style and power handling capabilities.
