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. It's 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. 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.
