Unique-Bargains 5 x DC 5V 9mm Buzzer Black
Pack of five DC 5 V continuous-sound buzzers with 9 mm plastic housings and 4.5 mm pin pitch
- DC 5V operation suits low-voltage circuits
- 9mm diameter fits tight enclosures
- 5mm pin pitch eases breadboard wiring
- Plastic housing keeps weight low
- Pack of five covers multiple projects
What it is
This pack contains five DC 5V electronic buzzers with a 9 mm diameter plastic housing and two pin terminals spaced at 4.5 mm pitch. They are suited for hobbyists, students or technicians adding audible alerts to low-voltage circuits, prototypes or small alarm devices.
Continuous operation
Each unit is rated for continuous sound output at the specified 5 V supply, drawing minimal current so heat buildup stays negligible during extended use. The compact 9 x 5.5 mm body fits tight board layouts without blocking adjacent components or airflow.
Before ordering
Verify that your circuit can provide a stable 5 V DC source and that the 4.5 mm pin spacing matches your PCB or breadboard layout. The black plastic housing measures 9 mm in diameter and 5.5 mm in height, so confirm the available clearance in your enclosure.

Questions about this item
How much current does the DC 5V 9mm buzzer draw when running continuously?
The buzzer is rated for DC 5V operation with low power consumption, making it suitable for extended use without excessive heat buildup.
Do I need a separate driver circuit or resistor to connect these 5V buzzers to a microcontroller?
Each buzzer has two pin terminals with 4.5mm pitch for direct low-voltage connection; verify your controller can source enough current at 5V.
Will the 4.5mm pin pitch match standard 0.1inch breadboards or perfboards I already use?
The 4.5mm pitch equals .17 inch, slightly narrower than .1 inch spacing, so an adapter or custom layout may be needed for standard boards.
