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. https://elecena.pl/product/2954618/speaker-pcb-mount 2012-05-19 https://elecena.pl/product/2954618/speaker-pcb-mount 2016-11-25 https://elecena.pl/product/2954618/speaker-pcb-mount 2016-11-28 https://elecena.pl/product/2954618/speaker-pcb-mount 2016-11-29 https://elecena.pl/product/2954618/speaker-pcb-mount 2016-12-09 https://elecena.pl/product/2954618/speaker-pcb-mount 2016-12-13 https://elecena.pl/product/2954618/speaker-pcb-mount 2017-11-24 https://elecena.pl/product/2954618/speaker-pcb-mount 2017-11-28 https://elecena.pl/product/2954618/speaker-pcb-mount 2018-05-05 https://elecena.pl/product/2954618/speaker-pcb-mount 2018-11-21 https://elecena.pl/product/2954618/speaker-pcb-mount 2018-11-27 https://elecena.pl/product/2954618/speaker-pcb-mount 2022-02-21 https://elecena.pl/product/2954618/speaker-pcb-mount 2025-06-17 https://elecena.pl/product/2954618/speaker-pcb-mount 2025-06-19
