SM160807-1

Overview

The DB Unlimited SM160807-1 is a dynamic speaker from the Power Micro series, designed for space-constrained applications. It features an 8 mm x 8 mm x 7 mm rectangular form factor with top porting. The unit operates at an impedance of 7 Ohms and handles up to 700 mW of power. It delivers a sound pressure level of 93 dB and has a frequency response starting at 600 Hz. Construction utilizes Polyetherimide (PEI) cones, enabling operation between -40°C and +85°C via solder pin termination.

Feature Summary

• Compact rectangular design optimized for limited space
• High output efficiency in small dimensions
• Robust thermal performance for varied environments

Applications

• IoT voice devices
• Handheld electronics
• Space-constrained audio modules

Procurement Notes

Verify the specific impedance rating of 7 Ohms against circuit requirements, as this differs from standard 8 Ohm configurations. Confirm that the 700 mW power handling aligns with the amplifier's output capabilities to prevent damage. Ensure the operating temperature range meets the environmental conditions of the final assembly. Check that the solder pin termination method is compatible with the PCB layout.

Selection Notes

Select this model when physical dimensions are restricted to approximately 8x8 mm. Choose it over higher-power variants if the application requires lower power consumption while maintaining high acoustic output. Consider the 7 Ohm impedance for matching with specific driver circuits. Verify that the top-port configuration fits the enclosure acoustics.

Part Context

This component belongs to the DB Unlimited Power Micro series, which focuses on delivering full-range audio solutions in miniature packages. The series is engineered to provide industry-leading power handling relative to size, targeting modern compact electronic devices where traditional speakers cannot fit.

Replacement Considerations

SM170808-2 offers similar performance but with an 8 Ohm impedance and 700 mW rating. SM180808-5 provides higher power handling at 1 W with 8 Ohm impedance. Both maintain the same series characteristics but differ in electrical specifications.
