20mm 3.5KHZ brass external  ceramic piezo transducer
  • FT-20T-3.5A1
  • The main component of the piezo element is piezoelectric ceramic, so it is called piezoelectric element. Ft-20t-3.5a1 is an External Drive Piezo element with diameter of 20mm and frequency of 3.5khz. In many cases, wire can be welded on the Piezoceramic Components, which can be customized according to the needs of different customers. The External Drive Piezo element can only rely on IC signals, or inductance circuits to match the frequency signal to sound. In general, iron buzzer will be much cheaper than copper buzzer. FBelec's buzzer tablet price is the most advantageous among all factory in China.
