SM280708-1

Overview

The SM280708-1 is a dynamic speaker manufactured by DB Unlimited. It features an 8-ohm impedance and a nominal power rating of 1 W. The resonant frequency is specified at 700 Hz, with an operating frequency range extending from 700 Hz to 10 kHz. The device delivers a sound pressure level of 103 dB. It utilizes a Mylar cone material and employs solder eyelets for termination. The unit is designed for frame mounting and includes top porting.

Feature Summary

• Dynamic transducer construction utilizing Mylar cone material
• Top ported acoustic design for directional sound output
• Solder eyelet termination method for circuit integration
• Frame mount installation style for secure enclosure attachment

Applications

• General purpose audio output devices
• Embedded installation designs requiring compact form factors
• Electronic equipment requiring 8-ohm impedance matching

Procurement Notes

Verify the specific datasheet version for environmental ratings and mechanical drawings before finalizing the design. Confirm that the solder eyelet termination type aligns with your PCB assembly process capabilities. Ensure the 1 W power handling is sufficient for your target application's acoustic requirements. Check for any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a compact, round dynamic speaker with top porting is required. The 8-ohm impedance suits standard low-voltage audio circuits. Consider the 700 Hz resonant frequency for applications where mid-range performance is prioritized over deep bass. Verify that the physical dimensions fit within the available enclosure space for frame mounting.
