Passive Buzzer

Product Description

✅ General Specification: ➡️ Product Type: Passive Buzzer ➡️ Buzzer Type: Passive / Externally Driven ➡️ Operating Voltage: Typically 3V–5V DC (model dependent) ➡️ Drive Type: External Oscillating Signal / PWM ➡️ Sound Output: Tone generated according to input frequency ➡️ Frequency Control: Yes, by changing input signal frequency ➡️ Polarity: Polarized ➡️ Mounting Type: Through-Hole (THT) ➡️ PCB Mountable: Yes ➡️ Compact & Lightweight: Yes ➡️ Low Power Consumption: Yes ➡️ Control Method: Microcontroller, PWM or oscillator circuit ➡️ Compatible With: Arduino, ESP32, ESP8266, STM32, Raspberry Pi and other microcontroller projects (interface dependent) ➡️ Applications: Musical tones, alarms, timers, notification systems, robotics, electronic projects and user-interface feedback ⚡ Key Features: Requires an external AC/PWM signal to generate sound Frequency can be controlled for different tones Suitable for musical notes and variable-frequency alerts Compact design for easy PCB installation Ideal for microcontroller and DIY electronics projects ⚠️ Important Note: A passive buzzer does not produce a continuous tone simply by applying DC power. It requires an alternating signal or suitable PWM drive. Always check the buzzer's rated voltage and polarity before use.
