SMS-1516MS-2-R

Overview

The SMS-1516MS-2-R is a surface-mount electromagnetic speaker manufactured by PUI Audio, Inc. It features a square form factor with dimensions of 15 mm x 15 mm and a height of 4.6 mm. The component operates with an impedance of 16 Ohms and has a power rating of 300 mW. Its frequency response ranges from 800 Hz to 20 kHz, with a self-resonant frequency of 800 Hz. The sound pressure level is rated at 85 dBA. It utilizes SMD/SMT termination for board mounting and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Surface-mount design for automated PCB assembly
• Square housing structure for compact integration
• Electromagnetic transduction technology

Applications

• General purpose audio output in consumer electronics
• Embedded systems requiring low-profile speakers
• Portable devices with limited internal volume

Procurement Notes

Verify the specific impedance and frequency response requirements against the official datasheet before procurement. Confirm that the surface-mount footprint matches the target PCB layout. Ensure the operating temperature range aligns with the final device environment. Check for RoHS compliance status if required by regional regulations. Validate the power handling capacity relative to the intended signal input levels.

Selection Notes

Select this component when a square, surface-mount speaker is required for space-constrained designs. The 16 Ohm impedance suits applications where higher impedance is preferred for current limiting. The 800 Hz to 20 kHz range is suitable for voice or general alert tones rather than full-range music reproduction. Consider the 300 mW power rating for low-volume signaling tasks.

Part Context

This part belongs to the PUI Audio series of surface-mount speakers. It is designed as a direct replacement for other small-form-factor electromagnetic transducers in portable electronics. The square shape distinguishes it from circular counterparts like the AS017 series, offering different spatial integration options for PCB designers.

Replacement Considerations

Direct substitutes may include other 16 Ohm surface-mount speakers from PUI Audio with similar dimensions. Verify mechanical compatibility and electrical parameters such as SPL and frequency response when cross-referencing with generic industry alternatives.
