Piezoelectric Diaphragms Notice 1

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.

c Notice (Handling)
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 R
1kΩ to 2kΩ. Instead of this measure, a diode may also be
applied as shown in Fig. B. IC IC

Fig. A Fig. B

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

may break or the soldering point come off.

Piezoelectric Ringers (PIEZORINGERr) Notice

c Notice (Soldering and Mounting)

1. Notice (Soldering and Mounting)
(1) Soldering Iron
(a) Immerse lead terminals up to 1.5mm from
component's body in soldering bath of +260±5°C
for 10±1.0 seconds, and then leave components
in natural conditions for 4 hours.
(b) Directly contact the lead terminal with the
tip of the soldering iron for +350±5°C for
3.0±0.5 seconds, and then leave components
in natural conditions for 4 hours.
(2) Reflow
The component cannot withstand reflow soldering.
2. Washing of the component is prohibited because
it is not sealed.

c Notice (Handling)
1. The component may be damaged if mechanical stress
exceeding specifications is applied.
2. Take care to protect the operating circuit from surge
voltage resulting from excessive force, falling, shock or
temperature change.
3. If DC voltage is applied to the component, silver migration
may occur. Please strictly avoid subjecting the
component to DC voltage for long periods.
4. The resistor should be used as shown in Fig. A.
A suitable resistance value should be chosen, preferably R
1kΩ to 2kΩ. Instead of this measure, a diode may also be
applied as shown in Fig. B. IC IC 6

Fig. A Fig. B

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

may break or the soldering point come off.
