 14 / 30 page5. DC Voltage and AC Voltage Characteristic1. The capacitance value of a high dielectric constant typecapacitor changes depending on the DC voltage applied.Please consider the DC voltage characteristics when acapacitor is selected for use in a DC circuit.1-1. The capacitance of ceramic capacitors may changesharply depending on the applied voltage. (See figure)Please confirm the following in order to secure thecapacitance.(1) Determine whether the capacitance change causedby the applied voltage is within the allowed range .(2) In the DC voltage characteristics, the rate ofcapacitance change becomes larger as voltageincreases, even if the applied voltage is belowthe rated voltage. When a high dielectric constanttype capacitor is used in a circuit that requires atight (narrow) capacitance tolerance (e.g., a timeconstant circuit), please carefully consider thevoltage characteristics, and confirm the variouscharacteristics in the actual operating conditions　of the system.2. The capacitance values of high dielectricconstant type capacitors changes dependingon the AC voltage applied.Please consider the AC voltage characteristicswhen selecting a capacitor to be used in aAC circuit.6. Capacitance Aging[ Example of Change Over Time (Aging characteristics) ]1. The high dielectric constant type capacitorshave an Aging characteristic in which the capacitancevalue decreases with the passage of time.When you use a high dielectric constant typecapacitors in a circuit that needs a tight (narrow)capacitance tolerance (e.g., a time-constant circuit),please carefully consider the characteristicsof these capacitors, such as their aging, voltage,and temperature characteristics. In addition,check capacitors using your actual appliancesat the intended environment and operating conditions.7.Vibration and Shock1. 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 ora crack in the dielectric material of the capacitor.Do not use a dropped capacitor because the quality and reliabilitymay be deteriorated.3. When printed circuit boards are piled up or handled, the corner　of another printed circuit boardshould not be allowed to hit the capacitor in order to avoida crack or other damage to the capacitor.Caution-100-80-60-40-200200102030DC Voltage (V)4050[Example of DC Voltage Characteristics]Sample: X7R(R7) Characteristics0.1μF, Rated Voltage 50VDC00.51AC Voltage (Vr.m.s.)1.52[Example of AC Voltage Characteristics]Sample: X7R(R7) Characteristics10μF, Rated Voltage 6.3VDC3020100-10-20-30-40-50-60FloorCrackMounting printed circuit boardCrack!20100-10-20-30-4010100100010000Time(h)C0G(5C)X7R(R7)X5R(R6)JEMCGC-2701X14
