!Note • Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.• This catalog has only typical specifications. Therefore, please approve our product specifi cations or transact the approval sheet for product specifi cations before ordering.C85E.pdfApr.7,2014High Voltage Ceramic Capacitors !Cautionc !Caution (Storage and Operating Condition)Operating and Storage EnvironmentThe insulating coating of capacitors does not form aperfect seal; therefore, do not use or storecapacitors in a corrosive atmosphere, especiallywhere chloride gas, sulfi de gas, acid, alkali, saltor the like are present. Also, avoid exposure tomoisture. Before cleaning, bonding or molding thisproduct, verify that these processes do not affectproduct quality by testing the performance of acleaned, bonded or molded product in the intendedequipment. Store the capacitors where thetemperature and relative humidity do not exceed -10to 40 degrees centigrade and 15 to 85%.Use capacitors within 6 months after delivery.Check the solderability after 6 months or more.FAILURE TO FOLLOW THE ABOVE CAUTIONS MAYRESULT, WORST CASE, IN A SHORT CIRCUITAND CAUSE FUMING OR PARTIAL DISPERSIONWHEN THE PRODUCT IS USED.c !Caution (Soldering and Mounting)1. Vibration and ImpactDo not expose a capacitor or its lead wires toexcessive shock or vibration during use.Excessive shock or vibration may cause fatiguedestruction of lead wires mounted on the circuitboard.Please take measures to hold a capacitor on thecircuit boards by adhesive, molding resin or anothercoating.Please confi rm there is no infl uence of holdingmeasures on the product with the intended equipment.2. SolderingWhen soldering this product to a PCB/PWB, do notexceed the solder heat resistance specifi cation ofthe capacitor. Subjecting this product to excessiveheating could melt the internal junction solder andmay result in thermal shocks that can crack theceramic element.Soldering the capacitor with a soldering iron shouldbe performed in following conditions.Temperature of iron-tip: 400 degrees C. max.Soldering iron wattage: 50W max.Soldering time: 3.5 sec. max.3. Bonding, Resin Molding and CoatingFor bonding, molding or coating this product, verifythat these processes do not affect the quality of thecapacitor by testing the performance of the bonded,molded or coated product in the intended equipment.When the amount of applications, dryness/hardeningconditions of adhesives and molding resins containingorganic solvents (ethyl acetate, methyl ethyl ketone,toluene, etc). are unsuitable, the outer coating resinof a capacitor is damaged by the organic solvents andit may result, worst case, in a short circuit.The variation in thickness of adhesive, molding resinor coating may cause outer coating resin crackingand/or ceramic element cracking of a capacitor in atemperature cycling.4. Treatment after Bonding, Resin Molding and CoatingWhen the outer coating is hot (over 100 degrees C.)after soldering, it becomes soft and fragile.Therefore, please be careful not to give it mechanicalstress.FAILURE TO FOLLOW THE ABOVE CAUTIONS MAYRESULT, WORST CASE, IN A SHORT CIRCUITAND CAUSE FUMING OR PARTIAL DISPERSIONWHEN THE PRODUCT IS USED.c !Caution (Handling)Vibration and ImpactDo not expose a capacitor or its lead wires toexcessive shock or vibration during use.Excessive shock or vibration may cause fatiguedestruction of lead wires mounted on the circuitboard.Please take measures to hold a capacitor on thecircuit boards by adhesive, molding resin or anothercoating.Please confi rm there is no infl uence of holdingmeasures on the product with the intended equipment.FAILURE TO FOLLOW THE ABOVE CAUTIONS MAYRESULT, WORST CASE, IN A SHORT CIRCUITAND CAUSE FUMING OR PARTIAL DISPERSIONWHEN THE PRODUCT IS USED.68

DEA/DEC/DEF Series (Temp. Char. CH, SL)Capacitance might change a little depending on thesurrounding temperature or an applied voltage.Please contact us if you intend to use thisproduct in a strict time constant circuit.2. DEB/DEC Series (Temp. Char. B, E, F)Capacitors have an aging characteristic, wherebythe capacitor continually decreases itscapacitance slightly if the capacitor is left onfor a long time. Moreover, capacitance might changegreatly depending on the surrounding temperature oran applied voltage. Therefore, it is not likely to besuitable for use in a time constant circuit.Please contact us if you need detailed information.3. DEH/DES SeriesCapacitance might change greatly depending on thesurrounding temperature or an applied voltage.Therefore, it is not likely to be suitable for use in atime constant circuit. Please contact us if you needdetailed information.69
