5VDC 12mm Mini Buzzer

The 5V 12mm Active Mini Buzzer is a compact and efficient audio signaling device commonly used in various electronic applications. Here’s a detailed overview of its specifications and characteristics:

Specifications

• Rated Voltage: 12 V
  • The buzzer is designed to operate optimally at 12 volts, though it can function within a specified range.
• Operating Voltage: 4~12 V
  • The buzzer is versatile and can operate effectively within this voltage range, making it suitable for different power sources and projects.
• Max Rated Current: ≤32 mA
  • It draws a maximum current of 32 milliamps, which is relatively low, making it efficient and easy to integrate into battery-operated or low-power circuits.
• Min. Sound Output at 10cm: 85 dB
  • The buzzer produces a minimum sound level of 85 decibels when measured from a distance of 10 centimeters. This volume is typically sufficient for alert signals in most applications.
• Resonant Frequency: 2300 ±300 Hz
  • It has a resonant frequency around 2300 Hz, with a tolerance of ±300 Hz. This frequency range is suitable for generating a clear and distinguishable sound.
• Operating Temperature: -20°C to 45°C
  • The buzzer can function within a temperature range from -20°C to 45°C, making it adaptable to various environmental conditions.
• Height: 9.16 mm (0.36″)
  • The height of the buzzer is compact, allowing it to fit in tight spaces.
• Diameter: 11.78 mm (0.46″)
  • The buzzer has a small diameter, emphasizing its miniaturized design.
• Weight: 1.6 g (0.057 oz)
  • It is lightweight, which is advantageous for portable and miniaturized applications.

Features

• Active Buzzer: Unlike passive buzzers, active buzzers have an internal oscillator and can produce sound directly when power is applied, without requiring an external signal or frequency source.
• Polarity: The buzzer has two pins, with the longer pin indicating the positive terminal. Proper connection is crucial for the buzzer to function correctly.
• Compact Size: Its small dimensions make it ideal for use in compact electronic devices and projects where space is limited.

Applications

• Electronic Projects: Suitable for hobbyist electronics, DIY projects, and prototyping where auditory alerts are needed.
• Alarm Systems: Can be used in alarm systems to signal conditions or notifications.
• Consumer Electronics: Useful in appliances and gadgets to provide audible feedback.

This mini buzzer offers a balance of size, efficiency, and sound output, making it a versatile component for a range of electronic applications.
