Five black cylindrical buzzers with two pins each, 12 by 9.5 mm plastic bodies

Unique-Bargains

Unique-Bargains DC 1.5V 30mA Continuous Sound Buzzer Black 12x9.5mm 5pcs

SKU CH-VG74-YM151

Five-piece pack of DC 1.5 V continuous-tone buzzers rated at 30 mA and 2400 Hz in 12 × 9.5 mm plastic housings

  • Low 1.5 V draw suits battery projects
  • 30 mA current keeps power use minimal
  • 2400 Hz tone cuts through ambient noise
  • 12 × 9.5 mm body fits tight enclosures
  • 5 mm pin pitch matches standard protoboards

What this buzzer does

This is a pack of five DC continuous sound buzzers rated for 1.5V and 30mA. Each unit has a 16 Ohm resistance and produces a 2400Hz tone through a plastic housing measuring 12 x 9.5mm with a 6.5mm pin pitch. The through-hole terminals simplify soldering onto perfboard or PCB layouts.

Who it suits and who it doesn't

Hobbyists adding audible alerts to microcontroller projects, breadboard prototypes or simple alarm circuits will find the voltage and current draw easy to drive from a GPIO pin or small transistor. Buyers who need a louder output, a different frequency, an AC-rated device or a surface-mount footprint should look at other components.

Behaviour under sustained load

The buzzer is specified for continuous operation at its rated voltage and current, so the 2400Hz tone remains steady as long as power is applied. Plastic construction and low 30mA draw keep self-heating minimal during extended use, while the fixed 16 Ohm resistance ensures consistent current without external limiting resistors.
