The capacitance change should be measured after 5min. at each
specified temp.stage.
(1)Temperature Compensating Type
The temperature coefficient is determind using the capacitance
measured in step 3 as a reference.
When cycling the temperature sequentially from step 1 through
5, the capacitance should be within the specified tolerance for
the temperature coefficient and capacitance change as Table A-1,A-2.
The capacitance drift is caluculated by dividing the differences
between the maximum and minimum measured values in the step
1,3 and 5 by the cap.value in step 3.
(2)High Dielectric Constant Type
The ranges of capacitance change compared with the 20℃/25℃
value over the temperature ranges shown in the table should be
within the specified ranges.

■ Storage and Operation condition
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℃ to +40℃ 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 the solderability and the 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

■ Soldering and Mounting
1.PCB Design
1. Notice for Pattern Forms
1-1. Unlike leaded components, chip components are susceptible to flexing stresses since they are mounted
directly on the substrate.
They are also more sensitive to mechanical and thermal stresses than leaded components.
Excess solder fillet height can multiply these stresses and cause chip cracking. When designing substrates,
take land patterns and dimensions into consideration to eliminate the possibility of excess solder fillet
height.
1-2.There is a possibility of chip crack caused by PCB expansion/contraction with heat.
Because stress for chip is different depend on PCB material and structure.Especially metal PCB
such as alumina has a greater risk of chip crack because of large difference of thermal expansion coefficient.
In case of chip below 0402 size, there is also the same possibility of crack with a single-layered glass epoxy
board.
