SMS-1508MS-R

Overview

The SMS-1508MS-R is a square electromagnetic speaker manufactured by PUI Audio, Inc. It features an 8 Ohm impedance and a power rating of 500 mW. The device delivers a sound pressure level of 87 dBA at a resonant frequency of 800 Hz. Designed for surface mount technology (SMD/SMT), it measures 15 mm in length and width with a depth of approximately 5 mm. The unit utilizes a Mylar cone and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Square form factor designed for space-constrained surface mount applications
• High sensitivity output of 87 dBA for efficient audio projection
• Robust thermal stability suitable for wide operating temperature environments

Applications

• Medical equipment indicators
• Industrial control panels
• Consumer electronics audio output

Procurement Notes

Verify the specific suffix and revision code against the manufacturer's latest datasheet to ensure compatibility with your design requirements. Confirm that the surface mount footprint matches your PCB layout exactly. Check for RoHS compliance status if required by your regulatory standards. Ensure the soldering profile supports the specified thermal limits during assembly.

Selection Notes

Select this component when a compact square footprint is required for SMD assembly. The 8 Ohm impedance suits standard low-voltage driver circuits. Consider the 500 mW power handling for moderate volume applications. Verify that the 800 Hz resonance aligns with the target acoustic performance needs of the final product.

Part Context

This part belongs to PUI Audio's line of electromagnetic transducers. It is distinct from similar models like the SMS-1508-2-R or SMS-1508MS-HT-R due to its specific power rating and package configuration. The series is engineered for reliable performance in various electronic devices requiring clear audible signals.

Replacement Considerations

Direct substitutes include SMS-1508MS-2-R and SMS-1508MS-HT-R, though electrical parameters such as power handling and frequency response may differ. Verify mechanical dimensions and terminal types before swapping to ensure board compatibility.
