Once application and assembly environments have been checked, the capacitor may be used in conformance with the rating and performance which are provided in both the catalog and the specifications. Use exceeding that which is specified may result in inferior performance or cause a short, open, smoking, or flaming to occur, etc. 2. Please consult the manufacturer in advance when the capacitor is used in devices such as: devices which deal with human life, i.e. medical devices; devices which are highly public orientated; and devices which demand a high standard of liability. Accident or malfunction of devices such as medical devices, space equipment and devices having to do with atomic power could generate grave consequence with respect to human lives or, possibly, a portion of the public. Capacitors used in these devices may require high reliability design different from that of general purpose capacitors. 3. Please use the capacitors in conformance with the operating temperature provided in both the catalog and the specifications. Be especially cautious not to exceed the maximum temperature. In the situation the maximum temperature set forth in both the catalog and specifications is exceeded, the capacitor's insulation resistance may deteriorate, power may suddenly surge and short-circuit may occur. The capacitor has a loss, and may self-heat due to equivalent series resistance when alternating electric current is passed therethrough. As this effect becomes especially pronounced in high frequency circuits, please exercise caution. When using the capacitor in a (self-heating) circuit, please make sure the surface of the capacitor remains under the maximum temperature for usage. Also, please make certain temperature rises remain below 20C. 4. Please keep voltage under the rated voltage which is applied to the capacitor. Also, please make certain the peak voltage remains below the rated voltage when AC voltage is super-imposed to the DC voltage. In the situation where AC or pulse voltage is employed, ensure average peak voltage does not exceed the rated voltage. Exceeding the rated voltage provided in both catalog and specifications may lead to defective withstanding voltage or, in worst case situations, may cause the capacitor to smoke or flame. 5. When the capacitor is to be employed in a circuit in which there is continuous application of a high frequency voltage or a steep pulse voltage, even though it is within the rated voltage, please inquire to the manufacturer. In the situation the capacitor is to be employed using a high frequency AC voltage or a extremely fast rising pulse voltage, even though it is within the rated voltage, it is possible capacitor reliability will deteriorate. 6. It is a common phenomenon of high-dielectric products to have a deteriorated amount of static electricity due to the application of DC voltage. Due caution is necessary as the degree of deterioration varies depending on the quality of capacitor materials, capacity, as well as the load voltage at the time of operation. 7. Do not use the capacitor in an environment where it might easily exceed the respective provisions concerning shock and vibration specified in the catalog and specifications. In addition, it is a common piezo phenomenon of high dielectric products to have some Voltage due to vibration or to have noise due to Voltage change. Please contact sales in such case. 8. If the electrostatic capacity value of the delivered capacitor is within the specified tolerance, please consider this when designing the respective product in order that the assembled product function appropriately. 9. Please contact us upon using conductive adhesives. Storage 1. If the component is stored in minimal packaging (a heat-sealed or chuck-type plastic bag), the bag should be kept closed. Once the bag has been opened, reseal it or store it in a desiccator. 2. Keep storage place temperature +5 to +35 degree C, humidity 45 to 70% RH. 3. The storage atmosphere must be free of gas containing sulfur and chlorine. Also, avoid exposing the product to saline moisture. If the product is exposed to such atmospheres, the terminals will oxidize and solderability will be effected. 4. Precautions 1)-3) apply to chip capacitors packaged in carrier tapes and bulk cases. 5. The solderability is assured for 12 months from our shipping date (six months for silver palladium) if the above storage precautions are followed. 6. Chip capacitors may crack if exposed to hydrogen (H2) gas while sealed or if coated with silicon, which generates hydrogen gas. Multilayer Ceramic Chip Capacitors Surface Mounting Information Dimensions for recommended typical land Land Pattern Sample capacitor c b a Soldering resist When mounting the capacitor to the substrate, it is important to consider carefully that the amount of solder (size of fillet) used has a direct effect upon the capacitor once it is mounted. a) The greater the amount of solder, the greater the stress to the elements. As this may cause the substrate to break or crack, it is important to establish the appropriate dimensions with regard to the amount of solder when designing the land of the substrate. b) In the situation where two or more devices are mounted onto a common land, separate the device into exclusive pads by using soldering resist Standard (Unit : mm) Size LW 03 0.60.3 a b c 0.20 to 0.30 0.25 to 0.35 0.30 to 0.40 05 1.00.5 0.30 to 0.50 0.35 to 0.45 0.40 to 0.60 105 1.60.8 0.70 to 1.00 0.80 to 1.00 0.60 to 0.80 21 2.01.25 1.00 to 1.30 1.00 to 1.20 0.80 to 1.10 316 3.21.6 2.10 to 2.50 1.10 to 1.30 1.00 to 1.30 32 3.22.5 2.10 to 2.50 1.10 to 1.30 1.90 to 2.30 42 4.52.0 2.50 to 3.20 1.80 to 2.30 1.50 to 1.80 43 4.53.2 2.50 to 3.20 1.80 to 2.30 2.60 to 3.00 52 5.72.0 4.20 to 4.70 2.00 to 2.50 1.50 to 1.80 53 5.72.8 4.20 to 4.70 2.00 to 2.50 2.20 to 2.60 55 5.75.0 4.20 to 4.70 2.00 to 2.50 4.20 to 4.70 CA series : Please refer applicable page.

Recommended chip position on PCB to minimize stress from PCB warpage (Not recommended) (Ideal) Actual Mounting 1) If the position of the vacuum nozzle is too low, a large force may be applied to the chip capacitor during mounting, resulting in cracking. 2) During mounting, set the nozzle pressure to a static load of 100 to 300 gf. 3) To minimize the shock of the vaccum nozzle, provide a support pin on the back of the PCB to minimize PCB flexture. Crack Support pin 4) Bottom position of pick up nozzle should be adjusted to the top surface of a substrate which camber is corrected. 5) To reduce the possibility of chipping and cracks, minimize vibration to chips stored in a bulk case. 6) The discharge pressure must be adjusted to the part size. Verify the pressure during setup to avoid fracturing or cracking the chips capacitors. Resin Mold 1) If a large amount of resin is used for molding the chip, cracks may occur due to contraction stress during curing. To avoid such cracks, use a low shrinkage resin. 2) The insulation resistance of the chip will degrade due to moisture absorption. Use a low moisture absorption resin. 3) Check carefully that the resin does not generate a decomposition gas or reaction gas during the curing process or during normal storage. Such gases may crack the chip capacitor or damage the device itself. Multilayer Ceramic Chip Capacitors Surface Mounting Information Soldering Method 1) Ceramic is easily damaged by rapid heating or cooling. If some heat shock is unavoidable, preheat enough to limit the temperature difference (Delta T) to within 130 degree Celsius. 2) The product size 1.00.5mm to 3.21.6mm can be used in reflow and wave soldering, and the product size of over 3.22.5mm, 0.60.3mm, and capacitor arrays can be used in reflow. Circuit shortage and smoking can be created by using capacitors which are used neglecting the above caution. 3) Please see our recommended soldering conditions. Please contact us if you use lead free solder because the peak temperature of lead free is different from non-lead free.
