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 8.5 x 8.5 x 3 mm electromagnetic passive buzzer. This surface-mount (SMD) component operates across a 3V to 5V voltage range. It delivers an 80 dB sound output at 5V. As a passive buzzer, it requires an external square wave signal, typically 4 kHz. This allows for customizable tones. Its side-firing design projects sound. It provides audio feedback. Applications include alarms, timers, and DIY prototypes.
