The products should be used within 6 monthsupon receipt.2) The capacitors must be operated and stored in an environment free of dewcondensation and these gases such as Hydrogen Sulphide, Hydrogen Sulphate,Chlorine, Ammonia and sulfur.3) Avoid storing in sun light and falling of dew.4) Do not use capacitors under high humidity and high and low atmospheric pressurewhich may affect capacitors reliability.5) Capacitors should be tested for the solderability when they are stored for long time.1-2. Handling in transportationIn case of the transportation of the capacitors, the performance of the capacitorsmay be deteriorated depending on the transportation condition.(Refer to JEITA RCR-2335C 9.2 Handling in transportation)2Circuit design Caution2-1. Operating temperatureOperating temperature should be followed strictly within this specification, especiallybe careful with maximum temperature.1) Do not use capacitors above the maximum allowable operating temperature.2) Surface temperature including self heating should be below maximum operatingtemperature.(Due to dielectric loss, capacitors will heat itself when AC is applied. Especially athigh frequencies around its SRF, the heat might be so extreme that it may damageitself or the product mounted on. Please design the circuit so that the maximumtemperature of the capacitors including the self heating to be below the maximumallowable operating temperature. Temperature rise at capacitor surface shall bebelow 20 C)3) The electrical characteristics of the capacitors will vary depending on thetemperature. The capacitors should be selected and designed in taking thetemperature into consideration.2-2. Operating voltage1) Operating voltage across the terminals should be below the rated voltage.When AC and DC are super imposed, V0-P must be below the rated voltage.— (1) and (2)AC or pulse with overshooting, VP-P must be below the rated voltage.— (3), (4) and (5)When the voltage is started to apply to the circuit or it is stopped applying, theirregular voltage may be generated for a transit period because of resonance orswitching.

Soldering5-1. Flux selectionAlthough highly-activated flux gives better solderability, substances which increaseactivity may also degrade the insulation of the chip capacitors. To avoid suchdegradation, it is recommended following.1) It is recommended to use a mildly activated rosin flux (less than 0.1wt% chlorine).Strong flux is not recommended.2) Excessive flux must be avoided. Please provide proper amount of flux.3) When water-soluble flux is used, enough washing is necessary.5-2.

No.Process5SolderingCondition2) Direct contact of the soldering iron with ceramic dielectric of chip capacitorsmay cause crack. Do not touch the ceramic dielectric and the terminations bysolder iron.5-7.Soldering rework using spot heaterHeat stress during rework may possibly be reduced by using a spot heater(also called a “blower”) rather than a soldering iron.It is applied only to adding solder in the case of insufficient solder amount.1) Reworking using a spot heater may suppress the occurrence of cracks in thecapacitor compared to using a soldering iron. A spot heater can heat up a capacitoruniformly with a small heat gradient which leads to lower thermalstress caused by quick heating and cooling or localized heating.Moreover, where ultra-small capacitors are mounted close together on a printedcircuit board, reworking with a spot heater can eliminate the risk of direct contactbetween the tip of a soldering iron and a capacitor.2) Rework conditionIf the blower nozzle of a spot heater is too close to a capacitor, a crack in thecapacitor may occur due to heat stress. Below are recommendations for avoidingsuch an occurrence.Keep more than 5mm between a capacitor and a spot heater nozzle.The blower temperature of the spot heater shall be lower than 400 C.The airflow shall be set as weak as possible.The diameter of the nozzle is recommended to be 2mm(one-outlet type).The size isstandard and common.Duration of blowing hot air is recommended to be 10s or less for CGA3 (CC0603),CGA4 (CC0805) and CGA5 (CC1206), and 30s or less for CGA6 (CC1210),CGA8(CC1812) and CGA9 (CC2220), considering surface area of the capacitorand melting temperature of solder.The angle between the nozzle and the capacitor is recommended to be 45degreesin order to work easily and to avoid partial area heating.As is the case when using a soldering iron, preheating reduces thermal stress oncapacitors and improves operating efficiency.・Recommended rework condition(Consult the component manufactures for details.)Distance from nozzle5mm and overNozzle angle45degreesNozzle temp.400 C and lessSet as weak as possible(The airflow shall be the minimum value necessary forsolder to melt in the conditions mentioned above.)φ2mm(one-outlet type)AirflowNozzle diameterBlowing duration10s and less (CGA3 [CC0603], CGA4 [CC0805], CGA5 [CC1206])30s and less (CGA6 [CC1210], CGA8 [CC1812], CGA9 [CC2220])・Example of recommended spot heater useOne-outlet type nozzleAngle : 45degrees— 19 —

No.Process5SolderingCondition3) Amount of solder should be suitable to from a proper fillet shape.Excess solder causes mechanical and thermal stress on a capacitor andresults in cracks. Insufficient solder causes weak adherence of the capacitorto the substrate and may result in detachment of a capacitor and deterioratereliability of the printed wiring board.See the example of appropriate solder fillet shape for 5-5.Amount of solder.5-8. Sn-Zn solderSn-Zn solder affects product reliability.Please contact TDK in advance when utilize Sn-Zn solder.5-9. Countermeasure for tombstoneThe misalignment between the mounted positions of the capacitors and the landpatterns should be minimized. The tombstone phenomenon may occur especiallythe capacitors are mounted (in longitudinal direction) in the same direction of thereflow soldering.(Refer to JEITA RCR-2335C Annex A (Informative) Recommendations to prevent thetombstone phenomenon)6Cleaning1) If an unsuitable cleaning fluid is used, flux residue or some foreign articles maystick to chip capacitors surface to deteriorate especially the insulation resistance.2) If cleaning condition is not suitable, it may damage the chip capacitors.2)-1. Insufficient washing(1) Terminal electrodes may corrode by Halogen in the flux.(2) Halogen in the flux may adhere on the surface of capacitors, and lower theinsulation resistance.(3) Water soluble flux has higher tendency to have above mentionedproblems (1) and (2).2)-2. Excessive washingWhen ultrasonic cleaning is used, excessively high ultrasonic energy outputcan affect the connection between the ceramic chip capacitor's body and theterminal electrode. To avoid this, following is the recommended condition.Power : 20 W/ max.Frequency : 40 kHz max.Washing time : 5 minutes max.2)-3. If the cleaning fluid is contaminated, density of Halogen increases, and it maybring the same result as insufficient cleaning.— 20 —

Printed circuit board cropping should be carried out using a boardcropping jig as shown in the following figure or a board cropping apparatus toprevent inducing mechanical stress on the board.(1)Example of a board cropping jigRecommended example: The board should be pushed from the back side,close to the cropping jig so that the board is not bent and the stress applied tothe capacitor is compressive.Unrecommended example: If the pushing point is far from the cropping jig andthe pushing direction is from the front side of the board, large tensile stress isapplied to the capacitor, which may cause cracks.Outline of rcuitboardDirection ofloadComponentsLoad pointSlotBoardcropping jigV-groove— 21 —SlotUnrecommendedDirectionof loadLoad pointPrintedcircuitboardComponentsV-grooveSlot
