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 an ultra-compact 8.5 x 8.5 x 3 mm electromagnetic passive buzzer, ideal for space-constrained electronic designs. This surface-mount (SMD) component operates efficiently across a 3V to 5V voltage range. It delivers a clear 80 dB sound output at 5V, ensuring effective audible alerts. As a passive buzzer, it requires an external square wave signal, typically 4 kHz, allowing for fully customizable tones and melodies. Its side-firing design optimizes sound projection in diverse applications. Engineers and hobbyists will find its flexibility invaluable for integrating precise audio feedback. Use it for alarms, timers, and various DIY prototypes. The MLT-8530 ensures reliable and customizable sound in your next project.
