About this product
A 9 x 5.5 mm passive buzzer rated at 3 V, with a 2.7 kHz frequency and 42 Ω impedance. Being passive, it needs an external oscillating signal, such as a PWM output from a microcontroller, to produce sound. It is used for alerts and beeps in small electronic projects.

Can I power it directly from a 3 V DC supply?
No. A passive buzzer needs an oscillating signal, typically a square wave or PWM near 2.7 kHz, to sound. A steady DC voltage alone will not produce a tone. For a constant tone from DC, use an active buzzer instead.
Does the drive frequency matter?
Yes. A passive buzzer is loudest when driven near its 2.7 kHz rated frequency, so set your tone generator close to that value for the best output.
