■Storage and Operation condition
1. If store the chip monolithic ceramic capacitors in an atmosphere consisting of high temperature or humidity,
sulfur or chlorine gases, contaminants attach to the surface of external electrode, and bondability with
conductive glue may deteriorate. Do not store the capacitors in an atmosphere consisting of corrosive gas
(e.g., hydrogen sulfide, sulfur dioxide, chlorine, ammoria gas, etc.). Storage environment must be at room
temperature of +5°C to +40°C and a relative humidity of 20% to 70%, and use the product within six months.
In case of packaging, do not open the last wrappend, polyethylene bag, till just before using.
After unpacking, immediately reseal, or store in a desiccator containing a desiccant.
ꢀ
2. 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 bondability with conductive glue and
electrical performance may deteriorate. Do not store capacitors under direct sunlight or in high huimidity conditions.
3. This product is chip monolithic ceramic capacitor limited to conductive glue mounting. Do not apply mounting method
other than conductive glue. Flow or reflow soldering can result in a lack of adhesive strength on the outer electrode by
poor wettability, which may result in chips breaking loose from the PCB.
■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 temperature characteristics, and
carefully confirm the various characteristics in actual use conditions and the actual system.
