(2) Soldering Iron
Electrode is directly soldered with the tip of soldering iron
at +350±5°C for 3.0±0.5 seconds.
(3) Other
Do not use strong acidity flux, more than 0.2wt% chlorine
content, in reflow soldering.
2. Wash
Do not clean or wash the component as it is not
hermetically sealed.
3. Coating
Do not apply conformal coating onto the component as
it's not hermetically sealed.
o Storage and Operating Conditions
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
after delivery under the conditions of a sealed and
unopened package. Please use the products within six
months after delivery. If you store the products for a long
time (more than six months), use carefully because the
solderability may be degraded 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
Sulfides and so on), because the characteristics may
be reduced in quality and may be degraded in
solderability due to storage in a chemical atmosphere.
(2) Please do not put the products directly on the floor
without anything under them to avoid damp places
and/or dusty places.
(3) Please do not store the products in places such as a
damp heated place or any place exposed to direct
sunlight or excessive vibration.
(4) Please use the products immediately after the
package is opened, because the characteristics may
be reduced in quality and/or be degraded in
solderability due to storage under poor condition.
(5) Please do not drop the products to avoid cracking of
ceramic element.
4. Other
Please be sure to consult with our sales representative or
engineer whenever the products are to be used in
conditions not listed above.
