(1) environmental conditions (a) to be exposed directly to water or salt water (b) to be dew formation (c) under conditions of corrosive gases such as hydrogen sulfide, sulfurous acid, chlorine and ammonia (2) under severe conditions of vibration or impact beyond the specified conditions in the specifications 2-1-6. dc voltage characteristics the capacitors (class 2) employ dielectric ceramics with dielectric constant having voltage dependency, and if applied dc voltage is high, capacitance may broadly change. for the specified capacitance, the following should be confirmed. (1) if capacitance change by applied voltage is within the allowable range, or if its application allows unlimited capacitance change. (2) dc voltage characteristics demonstrate, even if applied voltage is under the rated voltage, capacitance change rate increases with higher voltage (capacitance down). accordingly, when the capacitors are used for circuits with narrow capacitance allowable range such as time constant circuits, we recommend to apply lower voltage upon due consideration on capacitance aging in addition to the above.

(1) if the signal of a specific frequency is applied to the capacitors, electric and acoustic noise may be generated by resonating the characteristic frequency which is determined by the dimensions of the capacitor. as a measure to prevent this phenomenon, changing the size of the capacitor is effective to change its resonance frequency. also there is another measure changing the materials of the capacitors to the low-loss type, which has no (or less) piezoelectricity, or to class1. which has no (or less) piezoelectricity, or to class1 is also available. (2) vibration or impact applied to the capacitors may cause noise because mechanical force is converted to electrical signals (especially, application to around the amplifier unit) . as a measure to prevent this phenomenon, changing the materials of the capacitor to the low-loss type, which has no (or less) piezoelectricity, or to class1 is also available. (3) even if a whining sound is generated, there is no problem in product performance and reliability, however, check the worrisome phenomenon which may generate noise in your equipment. as a measure to prevent this phenomenon, changing to the capacitor different in characteristics, size and shape as shown in the (1), (2) above is effective. as the other measures, changing the mounting direction of the capacitors to bring under control the resonance with equipment bodies such as printed circuit board, or the capacitors are fixed with equipment bodies such as printed circuit board by adhesive may be effective. 2- 2.design of printed circuit board 2-2-1. selection of printed circuit board when the capacitors are mounted and soldered on an aluminum substrate, the substrate has influences on capacitor?s reliabilities against ?temperature cycles? and ?heat shock? because of difference in thermal expansion coefficient between them. it shall be carefully confirmed that the actual board applied does not deteriorate the characteristics of the capacitors. capacitance change vs. dc voltage dc voltage (v) time (h) time (h) heat treatment under ordinary temperature before and after heat treatment

(1) solder resist shall be utilized to equalize the amounts of solder on both sides. (2) if the capacitors are arranged in succession, solder resist shall be used to divide the pattern in the mixed mounting with a component with lead wires or in the arrangement near a chassis etc. see the table below. ng examples and recommended examples ng examples improved examples by pattern division mixed mounting with a component with lead wires the lead wire of a component with lead wires sectional view solder resist sectional view arrangement near chassis chassis solder (ground solder) sectional view solder resist sectional view retrofitting of component with lead wires soldering iron lead wire of retrofitted component sectional view solder resist sectional view lateral arrangement land portion to be excessively soldered solder resist 2-2-4. component layout the capacitors / components shall be placed on the pc board so as to have both electrodes subjected to uniform stresses, or to position the component electrodes at right angles to the grid glove or bending line to avoid cracking in the capacitors caused by the bending of the pc board after or during placing / mounting the capacitors / components on the pc board. (1) the recommended layout of the capacitor to minimize mechanical stress caused by warp or bending of a pc board is as below. ng example recommended example warp of circuit board lay out the capacitor sideways against the stressing direction (2) the following drawing is for your reference since mechanical stress near the dividing/breaking position of a pc board varies depending on the mounting position of the capacitors.

(2) if the storage place is humid, dusty, and contains corrosive gasses (hydrogen sulfide, sulfurous acid, hydrogen chloride and ammonia, etc.), the solderability of the terminal electrodes may deteriorate. also, storage in a place subjected to heating or exposed to direct sunlight causes deformed tapes and reels of taped version and/or components sticking to tapes, which results in troubles at the time of mounting. (3) the storage period shall be within 6 months. products stored for more than 6 months shall be checked their solderability before use. (4) the capacitors of high dielectric constant series (class 2, characteristic b,x7r,x5r and f,y5v) change in capacitance with the passage of time, ?capacitance aging?, due to the inherent characteristics of ceramic dielectric materials. the changed capacitance can be recovered by heat treatment to each initial value at the time of shipping. (see 2. operating condition and circuit design, 2-1-7. capacitance aging) (5) when the initial capacitance is measured, the capacitors shall be heat-treated at 150+0/-10 for 1 hour and then subjected to ordinary temperature and humidity for 48 4 hours before measuring the initial value. 3- 2.adhesives for mounting (1) the amount and viscosity of an adhesive for mounting shall be such that the adhesive shall not flow off on the land during it?s curing. (2) if the amount of adhesive is insufficient for mounting, the capacitor may fall after or during soldering. (3) if the adhesive is too low in its viscosity, the capacitors may be out of alignment after or during soldering. (4) adhesives for mounting can be cured by ultraviolet or infrared radiation. in order to prevent the terminal electrodes of the capacitors from oxidizing, the curing shall be dune at conditions of 160 max., for 2 minutes max. (5) if curing is insufficient, the capacitor may fall after or during soldering. also insulation resistance between terminal electrodes may deteriorate due to moisture absorption. in order to prevent these problems, the curing conditions shall be sufficiently examined. 3- 3.chip mounting consideration (1) when mounting the capacitors/components on a pc board, the capacitor bodies shall be free from excessive impact loads such as mechanical impact or stress in the positioning, pushing force and displacement of vacuum nozzles at the time of mounting. (2) the maintenance and inspections for chip mounter must be performed regularly. (3) if the bottom dead center of the vacuum nozzle is too low, the capacitor is cracked by an excessive force at the time of mounting. the following precautions and recommendations are for your reference in use. (a) set and adjust the bottom dead center of the vacuum nozzles to the upper surface of the pc board after correcting the warp of the pc board. (b) set the pushing force of the vacuum nozzle at the time of mounting to 1 to 3 n in static load. (c) for double surface mounting, apply a supporting pin on the rear surface of the pc board to suppress the bending of the pc board in order to minimize the impact of the vacuum nozzles. the typical examples are shown in the table below. (d) adjust the vacuum nozzles so that their bottom dead center at the time of mounting is not too low. (4) the closing dimensions of positioning chucks shall be controlled and the maintenance, checks and replacement of positioning chucks shall be regularly performed to prevent chipping or cracking of the capacitors caused by mechanical impact at the time of positioning due to worn positioning chucks. (5) maximum stroke of the nozzle shall be adjusted so that the maximum bending of pc board does not exceed 0.5mm at 90mm span. the pc board shall be supported by means of adequate supporting pins.
