SMS-1508MS-HT-R

Overview

The SMS-1508MS-HT-R is a square electromagnetic speaker transducer manufactured by PUI Audio, Inc. It features an 8-ohm impedance and a power rating of 800 mW. The device delivers a sound pressure level of 92 dBA at a resonant frequency of 800 Hz. Designed for surface mount installation, it utilizes a Mylar cone and operates within a temperature range of -40°C to +105°C.

Feature Summary

• High output capability with 92 dBA efficiency
• Extended high-temperature operational range up to 105°C
• Compact square form factor suitable for board mounting

Applications

• Industrial control panels requiring high-temperature resistance
• Automotive electronics in high-heat zones
• Medical devices needing compact acoustic signaling

Procurement Notes

Verify the specific suffix HT against official datasheets to confirm high-temperature ratings and material specifications. Ensure compatibility with surface mount assembly processes. Confirm RoHS compliance status through manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when standard speakers fail under elevated thermal conditions. The 800 mW rating supports moderate drive requirements. The square shape aids in efficient PCB layout utilization compared to round alternatives. Verify mechanical clearance for the specific package dimensions during design.

Part Context

This part belongs to PUI Audio's High-Temp Series, designed for environments exceeding standard commercial temperature limits. It serves as a specialized solution for industrial and automotive sectors where reliability under thermal stress is critical for acoustic signaling applications.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Evaluate other SMS series variants or AS series components only if they match the 8-ohm impedance, square footprint, and high-temperature operating range requirements.
