Product Information
Full details
This R-TECH Miniature Electronic Buzzer is designed for users needing a loud, clear audible alert in various electronic projects. Its primary benefit is its high, rich sound output, making it ideal for applications requiring reliable signaling. A potential caveat is its specific 5V power requirement, limiting its use with higher voltage systems without additional circuitry. Key features include its robust sound production and suitability for a wide range of devices from timers to safety equipment.

FAQs
What is the operating voltage for this buzzer?
This R-TECH Miniature Electronic Buzzer is designed to operate at 5V DC.
Can I use this buzzer with a 9V battery?
No, using a 9V battery directly will likely damage the buzzer as it is rated for 5V. You would need a voltage regulator to step down the voltage to 5V.
How do I connect this buzzer to an Arduino?
You can connect the positive terminal to a digital output pin of your Arduino and the negative terminal to a GND pin. You will need to write code to control the output pin to turn the buzzer on and off.
Is the sound volume adjustable?
This model does not have built-in volume adjustment. The sound output is fixed based on its design. For adjustable volume, external circuitry like a potentiometer might be needed.
What kind of applications is this buzzer suitable for?
It is ideal for telephone timers, calling devices, clocks, electronic toys, safety equipment, and general alert notifications in electronic projects.
What is the MPN for this product?
The Manufacturer Part Number (MPN) for this specific buzzer is 350905.
Does this buzzer require any specific type of signal to activate?
It requires a steady 5V DC voltage applied across its terminals to produce sound continuously. It can be activated intermittently by switching this DC voltage on and off.
Troubleshooting
Buzzer does not sound
Verify the 5V power supply is connected correctly to the positive terminal and ground to the negative terminal. Check all wire connections for continuity and ensure the power source is active and providing 5V. If controlled by a microcontroller, ensure the output pin is configured correctly and is sending a signal.
Buzzer sounds very faint or intermittent
Ensure the voltage supply is stable at 5V. If the voltage is dropping under load, the power source may be insufficient. Check wire gauge and connection quality for any resistance. The buzzer may be faulty if these steps do not resolve the issue.
Buzzer sounds distorted or 'crackly'
Confirm the buzzer is receiving exactly 5V. Over-voltage can cause distortion. Ensure connections are secure and not experiencing interference. If the issue persists, the buzzer itself may be damaged.
Pros and Cons
Pros
- Produces a loud and clear audible alert.
- Compact size for easy integration.
- Suitable for a wide variety of electronic projects.
- Reliable and consistent sound output.
- Efficient 5V operation.
Cons
- Requires a 5V power supply; not directly compatible with higher voltages.

Setup, Compatibility & Care
Setup:
- Identify Terminals: Locate the positive (+) and negative (-) terminals on the buzzer. These are typically marked or can be identified by the wire leads.
- Connect Power: Connect the positive terminal to a stable 5V DC power source. Connect the negative terminal to the ground (GND) of the power source.
- Integrate with Circuit: Wire the buzzer into your electronic project. This may involve connecting it directly to a power source through a switch, or to a digital output pin of a microcontroller (ensure the pin can supply sufficient current or use a transistor driver if needed).
Compatibility:
- Voltage: This buzzer is designed for 5V DC power supplies. Using voltages significantly higher or lower than 5V may result in improper operation or damage.
- Current: Ensure your power source can provide adequate current for the buzzer. Consult the product's detailed specifications if available for exact current draw.
- Signal Type: Operates on DC voltage. For pulsed or intermittent operation, it can be controlled by a microcontroller or other switching mechanism.
Care:
- Cleaning: Keep the buzzer clean and free from dust and debris. Use a dry, soft brush or compressed air. Avoid using liquids or solvents.
- Environment: Operate in environments within the recommended temperature and humidity ranges. Protect from moisture and extreme temperatures.
- Handling: Handle with care to avoid physical damage to the casing or internal components.
