SM200808-1

Overview

The SM200808-1 is a dynamic micro speaker manufactured by DB Unlimited. It features an 8 Ohms impedance and a nominal power rating of 400 mW to 1 W, depending on the specific datasheet source. The resonant frequency is specified at 600 Hz or 850 Hz across different listings, with a frequency response range extending up to 20 kHz. The unit has a round shape with a diameter of 20 mm and a height of approximately 6 mm. It utilizes Mylar for the cone material and employs solder pad termination for flush mount installation.

Feature Summary

• Dynamic transducer design optimized for compact audio applications
• Flush mount configuration suitable for tight enclosure spaces
• Solder pad termination for direct circuit board integration

Applications

• General purpose audio output in portable devices
• Embedded sound modules requiring low profile speakers
• Consumer electronics with limited internal volume

Procurement Notes

Verify the exact resonant frequency (600 Hz vs 850 Hz) and power rating (400 mW vs 1 W) against the manufacturer's current datasheet, as public sources show discrepancies. Confirm the physical height tolerance and cone material specifications before finalizing the design. Ensure the solder pad footprint matches the PCB layout requirements for reliable electrical connection.

Selection Notes

Select this component when a round, flush-mount dynamic speaker is required for general-purpose audio. Consider the 8 Ohms impedance for compatibility with standard amplifier outputs. Evaluate the trade-off between the varying reported resonant frequencies to ensure it aligns with the target application's acoustic performance needs. Verify RoHS compliance status through official documentation.

Part Context

This part belongs to the SM series of dynamic speakers from DB Unlimited, which focuses on providing comprehensive audio solutions. The series typically includes various sizes and impedances to address diverse engineering challenges. DB Unlimited leverages decades of industry experience to offer these components for maximizing customer design efficiency.

Replacement Considerations

Public data does not confirm specific substitute part numbers for the SM200808-1. Engineers should evaluate other DB Unlimited models within the same series that match the required 8 Ohms impedance, 20 mm diameter, and flush mount form factor.
