Handling Notice
1、 Please don't touch the component with the bare hand, because electrode maybe corroded.
2、 Take care to protect operating circuit surge voltage resulting excessive force falling shock temperature change.
3、 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.
4、 The resis tor should be used as shown in applied circuits, suitable resistance value should be chosen. Perfect 1 K Q to 2K , instead of measure a diode may also be applied as show in applied circuits.
5、 Avoid excessive pulling lead wire because wire may break or soldering point may come off.
6、 Piezoelectric Sounder are driven by an input frequency, The given frequency 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 square wave (Vb-p) or the other wave. When suers only have 1/2 duty square wave (Vb-p) use resistor or inductance parallel with sounder together.
