Description: This through-hole speaker is great for projects where you need something that sounds better than a piezo buzzer but don’t have room for a full-blown speaker. This 30mm diameter speaker is encased in plastic and will handle about 100mW of power.

5v won’t get you anywhere with this. ONLY for PCB mount, too big for a breadboard. Don’t buy with SMD boards.
