SMS-1508-2

Overview

The SMS-1508-2-R is an electromagnetic speaker manufactured by PUI Audio. It features a square shape with dimensions of 15 mm x 15 mm x 5 mm and utilizes SMD/SMT termination for board mounting. The unit operates at a frequency of 850 Hz with an impedance of 8 Ohms and delivers a sound pressure level of 87 dBA. It has a power rating of 300 mW and functions within a temperature range of -40°C to +85°C. The component uses Samarium Cobalt magnets and Mylar cones, belonging to the SMS series.

Feature Summary

• Square form factor designed for surface-mount board installation
• Utilizes Samarium Cobalt magnetic material for stable performance
• Operates effectively across a wide industrial temperature range

Applications

• Board-mounted audio output in compact electronic devices
• Industrial equipment requiring high-temperature stability
• Consumer electronics utilizing surface-mount assembly processes

Procurement Notes

Verify the specific suffix (e.g., -R) against official datasheets to confirm packaging type such as reel or cut tape. Ensure the part number matches the exact electrical parameters required for the design. Confirm RoHS compliance status through manufacturer documentation before procurement.

Selection Notes

Select this component when a low-profile square speaker is required for surface-mount technology. Consider the 8 Ohm impedance and 300 mW power handling for amplifier matching. The wide operating temperature range makes it suitable for environments exceeding standard commercial limits.

Part Context

This component belongs to the SMS series of speakers from PUI Audio. The series focuses on electromagnetic transducers optimized for board mounting. The SMS-1508-2-R variant specifically addresses needs for compact, square-shaped audio output solutions in modern electronics manufacturing.

Replacement Considerations

Check for direct substitutes within the SMS series that share identical 15x15x5 mm dimensions and 8 Ohm impedance. Verify that any replacement maintains the same SMD termination style and Mylar cone material compatibility.
