MLT-8530 - 8.5 x 3 mm Electromagnetic Passive Buzzer : 3V - 5V – SMD

MLT-8530 8.5x3mm SMD Electromagnetic Passive Buzzer (3V-5V)

The MLT-8530 is a compact 8.5 x 8.5 x 3 mm Electromagnetic Passive Buzzer, perfect for space-constrained electronic designs. This SMD component operates efficiently within a 3V to 5V range, delivering a clear 80 dB sound output at 5V. As a passive buzzer, it requires an external square wave signal, ideally at 4 kHz, allowing for fully customizable tones. Its side-firing design ensures effective sound projection in various applications. Engineers and hobbyists will appreciate its flexibility for audible alerts in timers, alarms, and DIY prototypes. Integrate the MLT-8530 for reliable and precise audio feedback in your next project.
