Description:

Ceramic Element (43mm, 0.8khz) Diaphragm

Diaphragm Applications:(Piezo ceramic element;Piezo chip)

1. For sound making:Clocks, Calculators, Telephones, Washingmachines, Various(Burglar alarms, etc);

2. For transduction: Embryo monitor, Heart reflectoscopereflector, pedometer, car alarm sensor.

Handing Notice:

1, Please do not touch the component with bare hand becauseelectrode may be corroded.

2, The component may be damaged if mechanical stress exceedingspecifications is applied.

3, Take care to protect operating circuit surge voltageresulting excessive force, falling, shock temperature change.

4, If DC voltage is applied to the component , silver migrationmay occur .Please pay full attention to avoid subjecting.

5, Avoid excessive pulling lead wire because wire may break orsoldering point may come off .

6, Applying Load on the center of the diaphragm may causecracking in the ceramic elements .When the diaphragm is supportedby the edge , the load should be only applied around the edge.

Soldering procedures:

When using a soldering iron , the optimum temperature forsoldering a lead wire to a metal plate is 340°c±10°c for 1-2 secondand the same temperature for the ceramic Silver electrode for 0.5second or less.
