■Storage and Operation condition

1. The performance of chip monolithic ceramic capacitors may be affected by the storage conditions.

1-1. Store the capacitors in the following conditions:

Room 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 solderability and packaging performance.

Therefore, please maintain the storage temperature and humidity. Use the product within six months after receipt ,

as prolonged storage may cause oxidation of the terminations (outer electrodes).

(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 huimidity

conditions

■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.

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 a AC circuit.

3.Applied Voltage

1. Do not apply a voltage to the capacitor that exceeds the rated voltage as called out in the specifications.

1-1. Applied voltage between the terminals of a capacitor shall be less than or equal to the rated voltage.

(1) When AC voltage is superimposed on DC voltage, the zero-to-peak voltage shall not exceed the rated DC voltage.

When AC voltage or pulse voltage is applied, the peak-to-peak voltage shall not exceed the rated DC voltage.

(2) Abnormal voltages (surge voltage, static electricity, pulse voltage, etc.) shall not exceed the rated DC voltage.

Typical Voltage Applied to the DC capacitor

DC Voltage DC Voltage+AC AC Voltage Pulse Voltage

(E：Maximum possible applied voltage.)

1-2. Influence of over voltage

Over voltage that is applied to the capacitor may result in an electrical short circuit caused by the breakdown

of the internal dielectric layers .

The time duration until breakdown depends on the applied voltage and the ambient temperature.

4.Type of Applied Voltage and Self-heating Temperature

1.Confirm the operating conditions to make sure that no large current is flowing into the capacitor due to the

continuous application of an AC voltage or pulse voltage.

When a DC rated voltage product is used in an AC voltage circuit or a pulse voltage circuit, the AC current

or pulse current will flow into the capacitor; therefore check the self-heating condition.

Please confirm the surface temperature of the capacitor so that the temperature remains within the upper limits

of the operating temperature, including the rise in temperature due to self-heating. When the capacitor is

used with a high-frequency voltage or pulse voltage, heat may be generated by dielectric loss.

1-1. The load should be contained to the level

　such that when measuring at atmospheric

　　temperature of 25°C, the product's self-heating

　　 remains below 20°C and the surface

temperature of the capacitor in the actual circuit

remains within the maximum operating

temperature.

5. DC Voltage and AC Voltage Characteristic

1. The capacitance value of a high dielectric constant type

capacitor changes depending on the DC voltage applied.

Please consider the DC voltage characteristics when a

capacitor is selected for use in a DC circuit.

1-1. The capacitance of ceramic capacitors may change

sharply depending on the applied voltage. (See figure)

Please confirm the following in order to secure the

capacitance.

(1) Determine whether the capacitance change caused

by the applied voltage is within the allowed range .

(2) In the DC voltage characteristics, the rate of

capacitance change becomes larger as voltage

increases, even if the applied voltage is below

the rated voltage. When a high dielectric constant

type capacitor is used in a circuit that requires a

tight (narrow) capacitance tolerance (e.g., a time

constant circuit), please carefully consider the

voltage characteristics, and confirm the various

characteristics in the actual operating conditions

　of the system.

2. The capacitance values of high dielectric

constant type capacitors changes depending

on the AC voltage applied.

Please consider the AC voltage characteristics

when selecting a capacitor to be used in a

AC circuit.

6. Capacitance Aging

[Example of Change Over Time (Aging characteristics) ]

1. The high dielectric constant type capacitors

have an Aging characteristic in which the capacitance

value decreases with the passage of time.

When you use a high dielectric constant type

capacitors 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.

7.Vibration and Shock

1. Please confirm the kind of vibration and/or shock, its condition, and any generation of resonance.

Please mount the capacitor so as not to generate resonance, and do not allow any impact on the terminals.

2. Mechanical shock due to being dropped may cause damage or

a crack in the dielectric material of the capacitor.

Do not use a dropped capacitor because the quality and reliability

may be deteriorated.

3. When printed circuit boards are piled up or handled, the corner

　of another printed circuit board

should not be allowed to hit the capacitor in order to avoid

a crack or other damage to the capacitor.

■Soldering and Mounting

1.Mounting Position

1. Confirm the best mounting position and direction that minimizes the stress imposed on the capacitor during flexing

or bending the printed circuit board.

1-1.Choose a mounting position that minimizes the stress imposed on the chip during flexing or bending of the board.

　[Component Direction]

Locate chip horizontal to the

direction in which stress acts.

(Bad Example) (Good Example)

[Chip Mounting Close to Board Separation Point]

It is effective to implement the following measures, to reduce stress in separating the board.

It is best to implement all of the following three measures; however, implement as many measures as possible

to reduce stress.

Stress Level

(1) Turn the mounting direction of the component parallel to the board separation surface.

A　>　D *1

(2) Add slits in the board separation part.

A　>　B

(3) Keep the mounting position of the component away from the board separation surface.

A　>　C

*1 A > D is valid when stress is added vertically to the perforation as with Hand Separation.

If a Cutting Disc is used, stress will be diagonal to the PCB, therefore A > D is invalid.

[Mounting Capacitors Near Screw Holes]

When a capacitor is mounted near a screw hole, it may be affected by the board deflection that occurs during

the tightening of the screw. Mount the capacitor in a position as far away from the screw holes as possible.

2.Information before Mounting

1. Do not re-use capacitors that were removed from the equipment.

2. Confirm capacitance characteristics under actual applied voltage.

3. Confirm the mechanical stress under actual process and equipment use.

4. Confirm the rated capacitance, rated voltage and other electrical characteristics before assembly.

5. Prior to use, confirm the solderability of capacitors that were in long-term storage.

6. Prior to measuring capacitance, carry out a heat treatment for capacitors that were in long-term storage.

7.The use of Sn-Zn based solder will deteriorate the reliability of the MLCC.

Please contact our sales representative or product engineers on the use of Sn-Zn based solder in advance.
