Passive Buzzer Piezo 3-12V

This 12085 passive buzzer is a compact and reliable sound output component designed for use with microcontrollers and embedded systems. Unlike active buzzers, this unit requires a PWM signal to generate sound, giving you full control over tone and frequency.

With a wide operating voltage range of 3V to 12V, it is suitable for use with platforms such as Arduino, ESP32, Raspberry Pi, and other digital systems. The buzzer features clearly marked positive and negative pins for easy integration and correct polarity connection.

For applications where a simple fixed tone is preferred without the need for PWM control, consider using an active buzzer alternative .
