Description:

A PCB Mount Buzzer is a compact, low-power sound-emitting component designed for direct mounting onto printed circuit boards (PCBs). It is used in various applications to provide audible alerts, alarms, and notifications in electronic circuits. The buzzer can be either active (self-oscillating) or passive (requires an external driving signal), making it suitable for different microcontroller-based and industrial applications.

Specifications:

• Operating Voltage: 3V – 12V DC (varies by model)
• Current Consumption: Typically 5mA – 30mA
• Sound Output: 80dB – 100dB at 10cm distance
• Frequency Range: 2kHz – 4kHz (typical operating range)
• Mounting Type: Through-hole or surface-mount for PCB integration
• Polarity: Some models have polarity marking (active buzzers)
• Size: Varies depending on model (typically 9mm – 12mm diameter)

Features:

• Compact and Easy to Mount: Designed for PCB integration with through-hole or SMD configuration
• Loud and Clear Sound: Produces a clear beep or continuous tone for alert applications
• Low Power Consumption: Operates efficiently on minimal power input
• Available in Active & Passive Types: Active buzzers have built-in oscillators, while passive buzzers require an external signal
• Durable and Reliable: Designed for long-term operation in electronic circuits

Applications:

• Electronic Alarms and Security Systems: Used in burglar alarms, fire alarms, and security alert devices
• Embedded Systems and Microcontroller Projects: Provides audio feedback in Arduino, PIC, STM32, and Raspberry Pi applications
• Appliances and Industrial Equipment: Common in washing machines, microwaves, and automation warning systems
• Medical Devices: Alerts in patient monitoring systems and diagnostic tools
• Automotive Warning Systems: Used in seatbelt reminders, parking sensors, and vehicle alarms
