!Caution
c Storage and Operation Conditions
1. The performance of chip monolithic ceramic capacitors
may be affected by the storage conditions.
1-1. Store capacitors in the following conditions:
Temperature of +5°C to +40°C and a Relative
Humidity of 20% to 70%.
(1) Sunlight, dust, rapid temperature changes,
corrosive gas atmosphere or high temperature
and humidity conditions during storage may affect
solderability and packaging performance.
Please use product within six months of receipt.
(2) Please confirm solderability before using after six
months. Store the capacitors without opening the
original bag. Even if the storage period is short, do
not exceed the specified atmospheric conditions.
1-2. Corrosive gas can react with the termination
(external) electrodes or lead wires of capacitors, and
result in poor solderability. Do not store the
capacitors in an atmosphere consisting of corrosive
gas (e.g., hydrogen sulfide, sulfur dioxide, chlorine,
ammonia gas, etc.).
1-3. Due to moisture condensation caused by rapid
humidity changes, or the photochemical change
caused by direct sunlight on the terminal electrodes
and/or the resin/epoxy coatings, the solderability and
electrical performance may deteriorate. Do not store
capacitors under direct sunlight or in high humidity
conditions.
c Rating
1. Temperature Dependent Characteristics
1. The electrical characteristics of the capacitor can change
with temperature.
1-1. For capacitors having larger temperature
dependency, the capacitance may change with
temperature changes.
The following actions are recommended in order to
ensure suitable capacitance values.
(1) Select a suitable capacitance for the operating
temperature range.

(2) The capacitance may change within the rated
temperature.
When you use a high dielectric constant type
capacitor in a circuit that needs a tight (narrow)
capacitance tolerance (e.g., a time-constant
circuit), please carefully consider the
characteristics of these capacitors, such as their
aging, voltage, and temperature characteristics.
In addition, check capacitors using your actual
appliances at the intended environment and
operating conditions.
