!Caution · Notice
!Caution (Rating)
Do not use the product beyond the rated temperature
range and the rated voltage range. If using it beyond this
range, characteristics might degrade.
Notice (Storage and Operating Condition)
1. Product Storage Condition
Please store the products in a room where the
temperature/humidity is stable and avoid places where
there are large temperature changes. Please store the
products under the following conditions.
Temperature: -10 to +40°C
Humidity: 15 to 85%R.H.
2. Expiration Date on Storage
Expiration date (shelf life) of the products is six months
aer delivery under the condition of a sealed and
unopened package. Please use the products within six
months aer delivery. If you store the products for a long
time (more than six months), use carefully because the
products may be degraded in solderability due to storage
under poor conditions.
Please confirm solderability and characteristics for the
products regularly.
3. Notice on Product Storage
(1) Please do not store the products in a chemical
atmosphere (Acids, Alkali, Bases, Organic gas, Sulfides
and so on), because the characteristics may be reduced
in quality, may be degraded in solderability due to
storage in a chemical atmosphere.
Notice (Soldering and Mounting)
1. Mounting
When mounting a pin terminal type of product to the
printed circuit board, please insert the pin terminal along
the hole of the board. If the product is pressed so that the
terminal is not in the hole, the pin terminal would be
pushed into the inside of the product and the sounds
might become unstable.
2. Double-sided through-hole Board
Please avoid using a double-sided through-hole board. If
the melted solder touched the base of a pin terminal, a
part of the plastic case would melt and the sounds might
become unstable.
3. Soldering Conditions
(1) Flow soldering conditions for pin terminal type
· Temperature: within +260°C±5°C
· Time: within 10±1 sec.
· Soldering part is the lead terminals excluding 1.5mm
from product body.
(2) Soldering condition by soldering iron for pin terminal
type
· Temperature: within 350±5°C
(2) Please do not store the products directly on the floor
without anything under them to avoid damp places
and/or dusty places.
(3) Please do not store the product in places such as in a
damp heated place or any place exposed to direct
sunlight or excessive vibration.
(4) Please use the products immediately aer the
package is opened, because the characteristics may be
reduced in quality, and/or be degraded in solderability
due to storage under poor conditions.
(5) Please be sure to consult with our sales representative
or engineer whenever the products are to be used in
conditions not listed above.
4. Operating Environment
This product is designed for application in an ordinary
environment (normal room temperature, humidity and
atmospheric pressure).
Do not use the products in a chemical atmosphere such
as chlorine gas, acid or sulfide gas.
Characteristics might degrade by a chemical reaction
with the material used in products.
· Time: within 3.0±0.5 sec.
· Soldering part is the lead terminals excluding 1.5mm
from product body.
4. Washing
Please avoid washing, since this product is not a sealed
structure.
5. Aer Mounting the Product
(1) If the product is floating from the printed circuit board,
please do not push it. When pressing, the pin terminal is
pushed inside the product and the sounds might
become unstable.
(2) Please do not apply force (shock) to the product. If
force is applied, the case might come o.
(3) If the case comes o, please do not reassemble. Even
if it seems to have returned to the original, the sounds
might become unstable.
(4) Please do not blow air onto the product directly.
Blown air applies force to the piezoelectric diaphragm
through the sound emission hole; cracks could occur
and then the sounds could become unstable.
