The main attribute characters for Piezo buzzer/ piezo transducer, as follows

Material: Piezoceramics; ABS/PPOABS/PPO/Al

Configuration: Mounting ears, or not

Connection terminal:Pin, Wire, or SMD

Product types: External drive, Self drive (With Circuit Built in)


The main parameter values of piezo buzzer:

Handling Notice:

1. Take care to protect operating circuit surge voltage resulting excessive force falling shock temperature change.

2. If DC voltage is applied to the competent silver migration may occur please pay full attention to avoid subjecting the component to DC voltage for long periods.

3. The resistor should be used as shown in applied circuits, suitable resistance value should be chosen.

4. Avoid excessive pulling lead wire because wire may break or soldering point may come off.

5. Piezoelectric Sounder are driven by an input frequency, the givenfrequency characteristics can be obtained when applying square wave or sine wave. The users must know the facts that the characteristics of frequency may be quite change or bad sound in different shapes with the applied various waves, like 1/2 duty spuare wave(Vo-p) or the other wave. When users only have 1/2 duty square wave (Vo-p) use resistor or inductance parallel with buzzer together.


Soldering and Mounting:

-Please do not cover the hole with tape or other obstacles, as this will produce irregular operation.
