SM150808-2

Overview

The DB Unlimited SM150808-2 is a dynamic surface mount micro speaker designed for compact audio applications. It features an 8 Ohm impedance and a resonant frequency of 850 Hz, with an operational frequency range extending from 850 Hz to 20 kHz. The device delivers a sound pressure level of 87 dBA at 10 cm and has a rated power capacity of 500 mW. Constructed with a Mylar cone, it utilizes SMD/SMT solder pad termination for automated assembly. The unit measures approximately 15 mm by 8 mm with a height of 8 mm, ensuring low profile integration in space-constrained electronic devices.

Feature Summary

• Surface mount design facilitates automated PCB assembly
• Mylar cone construction provides lightweight diaphragm response
• Compact rectangular form factor suitable for tight enclosures

Applications

• Portable consumer electronics audio output
• Miniature intercom systems
• Embedded alarm or notification devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm terminal type and packaging configuration. Ensure the selected variant matches the required impedance and power rating for the target circuit. Cross-reference the RoHS compliance status with the latest regulatory documentation before finalizing procurement orders.

Selection Notes

Select this component when a low-profile surface mount speaker is required for high-frequency reproduction up to 20 kHz. The 8 Ohm impedance aligns with standard audio driver outputs. Consider the 850 Hz self-resonant frequency as the lower limit for effective acoustic performance in small enclosures.

Part Context

This model belongs to the SM series of dynamic micro speakers manufactured by DB Unlimited. The series focuses on miniaturized transducers utilizing surface mount technology. These components are engineered for integration into portable devices where traditional through-hole speakers cannot fit due to spatial constraints.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing PCB footprints and electrical requirements before considering alternative manufacturers.
