SMS-2030MS

Overview

The SMS-2030MS is a square, surface-mount electromagnetic speaker manufactured by PUI Audio. It features a 30-ohm impedance and a rated input power of 500 mW to 800 mW. The device operates within a frequency range of 760 Hz to 10 kHz and delivers a sound pressure level of 91 dB. Designed for heat-resistant applications, it utilizes top-port acoustic output and SMD/SMT termination types. The component is suitable for board mounting in compact electronic assemblies requiring reliable audio transduction.

Feature Summary

• Heat-resistant construction for elevated temperature environments
• Surface-mount design for automated assembly integration
• Top-port acoustic output configuration

Applications

• Consumer electronics audio modules
• Industrial control panel indicators
• Medical device alarm systems

Procurement Notes

Verify the specific datasheet version for exact thermal resistance and soldering profile requirements. Confirm that the 500 mW to 800 mW power rating aligns with your circuit's maximum output capabilities. Ensure PCB layout accommodates the square form factor and top-port clearance. Check RoHS compliance documentation for regulatory adherence in target markets.

Selection Notes

Select this component when high-frequency response up to 10 kHz is required in a small footprint. The 30-ohm impedance suits drivers designed for higher voltage or lower current outputs compared to standard 8-ohm speakers. Consider the heat-resistant properties if the operating environment exceeds standard consumer temperature limits. Verify mechanical constraints for the square package dimensions before finalizing the enclosure design.

Part Context

This part belongs to PUI Audio’s SMS series of general-purpose electromagnetic speakers. The series focuses on providing reliable audio solutions for various electronic devices through standardized surface-mount packages. The SMS-2030MS specifically addresses needs for moderate power handling and broad frequency response in compact designs.

Replacement Considerations

Direct substitutes may include other square SMD speakers from PUI Audio with similar 30-ohm impedance and top-port configurations. Verify dimensional compatibility and acoustic performance curves against the original specification sheet.
