Piezoelectric Diaphragms Notice

1
■ Notice (Soldering and Mounting)
1. Applying load on the center area of the diaphragm
may cause clack in the ceramic element. When the
diaphragm is supported by edge, the load should be
only applied around edge.
2. Please consult with Murata or Murata
representative, in case of soldering on the
component.
■ Notice (Handling)
1. Please do not touch the component with bare hand
because electrode may be corroded.
2. The component may be damaged if mechanical stress
over this specification is applied.
3. Please pay attention to protect operating circuit from
surge voltage provided by something of force such as
falling, shock and temperature changing.
4. If DC voltage is applied to the component, silver migration
may occur. Please pay full attention not to subject 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
1kΩ to 2kΩ. Instead of this measure, a diode may also be
applied as shown in Fig. B.
6.Please pay enough attention not to pull lead wire too
much because wire may be broken or soldering point may
come off.

Piezoelectric Sound Components
Piezoelectric Sounders External Drive Pin Type
Now, microcomputers are widely used for microwave
ovens, air conditioners, cars, toys, timers, and other
alarm equipment. Externally driven piezoelectric
sounders are used in digital watches, electronic
calculators, telephones and other equipment. They are
driven by a signal (ex, 2048Hz or 4096Hz) from an LSI
and provide melodious sound.
■ Features
1. Low power consumption.
2. No contacts therefore, no noise and highly reliable.
■ Applications
• Telephone ringers.
• Various office equipment such as PPCs, printers and
keyboards.
• Various home appliances such as microwave ovens.
• Confirmation sound of various audio equipment.

Piezoelectric Sound Components
Piezoelectric Sounders External Drive Lead Wire Type
Now, microcomputers are widely used for microwave
ovens, air conditioners, cars, toys, timers, and other
alarm equipment. Externally driven piezoelectric
sounders are used in digital watches, electronic
calculators, telephones and other equipment. They are
driven by a signal (ex, 2048Hz or 4096Hz) from an LSI
and provide melodious sound.
■ Features
1. Low power consumption.
2. No contacts therefore, no noise and highly reliable.
■ Applications
• Telephone ringers.
• Various office equipment such as PPCs, printers and
keyboards.
• Various home appliances such as microwave ovens.
• Confirmation sound of various audio equipment.

■ Notice (Soldering and Mounting)
Washing of the component is not acceptable,
because it is not sealed.
■ Notice (Handling)
1. The component may be damaged if mechanical stress
over this specification is applied.
2. Please pay attention to protect operating circuit from
surge voltage provided by something of force such as
falling, shock and temperature changing.
3. If DC voltage is applied to the component, silver migration
may occur. Please pay full attention not to subject 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
1kΩ to 2kΩ. Instead of this measure, a diode may also be
applied as shown in Fig. B.
5. Please pay enough attention not to pull lead wire too
much because wire may be broken or soldering point may
come off.

Piezoelectric Sound Components
Piezoelectric Ringers (PIEZORINGERr)
As the result of rapid development of ICs in
telephones, demand for piezoelectric sounder as
telephone ringers has also rapidly increased. To
effectively satisfy this rising demand, Murata
provides a suitable piezoelectric sounder called
"PIEZORINGER", with the following features.
■ Features
1. Extremely clear sound.
2. Since it is voltage driven, the power consumption
is quite negligible.
3. It can be driven directly from ICs.
4. Extremely thin and light.

2. Ultra-thin and light-weight.
3. High impedance with less power consumption.
4. No electric noise, because they have no mechanical
contacts.
5. Direct drive by IC is available.

Piezoelectric Speakers (CERAMITONEr) Notice
36
10
■ Notice (Soldering and Mounting)
1. Applying load on the center area of the speaker may
cause clack in the ceramic element. When the
speaker is supported by edge, the load should be
only applied around edge.
2. Washing of the component is not acceptable, because
it is not sealed.
■ Notice (Handling)
1. Please do not touch the component with bare hand
because electrode may be corroded.
2. The component may be damaged if mechanical stress
over this specification is applied.
3. Please pay attention to protect operating circuit from
surge voltage provided by something of force such as
falling, shock and temperature changing.
4. If DC voltage is applied to the component, silver migration
may occur. Please pay full attention not to subject 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
1kΩ to 2kΩ. Instead of this measure, a diode may also be
applied as shown in Fig. B.
6.Please pay enough attention not to pull lead wire too
much because wire may be broken or soldering point may
come off.
