Miniature Buzzer 3V

These Miniature Buzzers are a low-cost miniature transistor oscillator 3V buzzer with flying leads. They have a single-tone frequency of 400hz and a sound output of 70dB @ 200mm. They are rated for 2V – 4V (3V nominal) and a current of 25mA and the driver circuitry is built in. These buzzers are supplied in packs of 10.

The buzzer unit is L23mm x W17mm x H15.5mm, with fixing centres at 27.5mm, which gives a total length measurement of 33.5mm. The colour-coded (red & black) flying leads are 100mm. To ensure optimum performance and to protect the buzzer, ensure that the supply (e.g. batteries) is connected in the correct configuration.
