Piezoelectric Diaphragms Notice

c Notice (Soldering and Mounting)

1. Applying load on the center area of the diaphragm

may cause cracking in the ceramic element. When

the diaphragm is supported by the edge, the load

should be applied only around the edge.

2. Please consult with a Murata representative if

soldering of the component is needed.

1. Please do not touch the component with a bare hand

because the electrode may become corroded.

2. The component may be damaged if mechanical stress

exceeding specifications is applied.

3. Take care to protect the operating circuit from surge

voltage resulting from excessive force, falling, shock or

temperature change.

4. If DC voltage is applied to the component, silver migration

may occur. Please strictly avoid subjecting the

component to DC voltage for long periods.

5. The resistor should be used as shown in Fig. A.

A suitable resistance value should be chosen, preferably

1k

Ω to 2kΩ. Instead of this measure, a diode may also be

applied as shown in Fig. B.

6. Avoid excessive pulling of the lead wire because the wire

may break or the soldering point come off.
