Piezo Diaphragm 3 Electrodes - Self Drive 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. Dimensions: D 35 x d 25 x t 0.10 x T 0.22mm Resonant frequency fr: 1.8KHz |
