9×5.5mm SMD Magnetic Buzzer

MLT-9055 SMD Electromagnetic Buzzer | Surface-Mount Magnetic Buzzer for PCB Assembly The MLT-9055 is an Electromagnetic Buzzer in SMD format, listed in the product specification as an electromagnetic chip buzzer. As an SMD Magnetic Buzzer, it is designed for direct surface mounting on PCBs, replacing traditional pinned 09-series audible devices in space-limited electronics. This page focuses on physical parameters, reflow soldering, and PCB integration. For tonal comparison, it is also positioned against SMD Piezo Buzzer and Mylar Speaker solutions where different SPL, power, or frequency requirements apply. 1. Product Introduction MLT-9055 belongs to the passive SMD electromagnetic buzzer family. The specification defines the product type as “Electromagnetic chip Buzzer” and the model as MLT-9055. Compared with a Mechanical Buzzer that relies on moving contacts or armature mechanisms, the electromagnetic SMD structure uses a coil, magnet, and diaphragm to generate sound under an exte…
