Part Number: SMPD3SD35T25F18
The sound source of a piezoelectric sound component is a piezoelectric diaphragm. It has the advantages of simple structure, stable performance and high reliability. A piezoelectric diaphragm consists of a piezoelectric ceramic plate which has electrodes on both sides and a metal plate (brass or stainless steel, etc.). It is not only the core element of piezoelectric buzzers and the alarms, but also used as shock sensors in many sensitive equipments.
