3.3 Product Storage
3.3.1 Please do not store the products in a chemical atmosphere (Acids, Alkali, Bases, Organic gas, Sulfides
atc), because the characteristics may be reduced in quality, and/or be degraded in a chemical
atmosphere.
3.3.2 Please do not put the products directly on the floor without anything under them to avoid damp places
and/or dusty places.
3.3.3 Please do not store the products in the places such as: in a damp heated place, in a place where direct
sunlight comes in, in place applying vibrations.
3.3.4 Please use the products immediately after the package is opened, because the characteristics may be
reduced in quality, and/or be degraded in the solderability due to storage under the poor condition.
3.3.5 Please do not drop the products to avoid cracking of ceramic element.
3.4 Please be sure to consult with our sales representative or engineer whenever and prior to using the
products.
3.5 Washing of the component is not acceptable, because it is not sealed.
3.6 The component may be damaged if mechanical stress over this specification is applied.
Please pay attention to protect operating circuit from surge voltage provided by something of force such
as falling,shock and temperature changing.
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.
The resistor shoud 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.
