3351

Overview

The Adafruit Industries LLC part number 3351 is a mono enclosed speaker designed for audio output applications. It features a 4-ohm impedance and a maximum power handling capacity of 3 watts. The physical dimensions are specified as 24mm by 63mm, with a rectangular mounting hole configuration. The device utilizes wire leads for termination and includes a top port for sound emission. This component is classified as an active product suitable for integration into electronic projects requiring compact audio solutions.

Feature Summary

• Enclosed mono speaker design
• Top port sound emission
• Rectangular form factor

Applications

• Embedded audio projects
• Educational electronics kits
• Portable device prototyping

Procurement Notes

Verify the specific impedance and power rating requirements against your amplifier or driver circuit to ensure compatibility. Confirm that the wire lead termination method aligns with your assembly process. Check the physical dimensions to ensure the rectangular footprint fits within your designated enclosure space. Ensure the top port orientation allows for unobstructed sound projection in the final design.

Selection Notes

Select this component when a compact, low-power audio solution is required for embedded systems. The 4-ohm impedance is standard for many microcontroller-driven audio amplifiers. Consider the 3-watt power rating to determine if it meets the volume requirements of the application. The enclosed design simplifies mechanical integration compared to bare drivers.
