Soberton’s ultra-miniature magnetic buzzers are some of the smallest in the industry, offering significant board space savings. They come in a 6.6 mm round package with a height of only 3.5 mm and provide low current consumption. They are offered in 1.5 V and 3 V versions and require an external drive to operate. This miniature series offers engineers an extremely small size buzzer to add a beep or indicator to any application. They have a 3 kHz frequency with an SPL level of 75 dB and feature a top mount sound port.
