Caution

1. The performance of chip multilayer ceramic capacitors

and chip EMIFIL NFM series (henceforth just “capacitors”)

may be aected by the storage conditions.

Please use them promptly aer delivery.

1-1. Maintain appropriate storage for the capacitors using

the following conditions: Room Temperature of +5 to

+40°C and a Relative Humidity of 20 to 70%.

High temperature and humidity conditions and/or

prolonged storage may cause deterioration of the

packaging materials. If more than six months have

elapsed since delivery, check packaging, mounting,

etc. before use.

In addition, this may cause oxidation of the electrodes.

If more than one year has elapsed since delivery, also

check the solderability before use.

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.

Storage and Operation Conditions

1. Temperature Dependent Characteristics

1. The electrical characteristics of a 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.

2. Measurement of Capacitance

1. Measure capacitance with the voltage and frequency

speciﬁed in the product speciﬁcations.

1-1. The output voltage of the measuring equipment may

decrease occasionally when capacitance is high.

Please conﬁrm whether a prescribed measured

voltage is impressed to the capacitor.

1-2. The capacitance values of high dielectric constant

type capacitors change depending on the AC voltage

applied. Please consider the AC voltage

characteristics when selecting a capacitor to be used

in an AC circuit.
