3 / 23 page Reference only EGD08E 2 / 22 6. SOLDERING When soldering this product to a PCB/PWB, do not exceed the solder heat resistance specification of the capacitor. Subjecting this product to excessive heating could melt the internal junction solder and may result in thermal shocks that can crack the ceramic element. When soldering capacitor with a soldering iron, it should be performed in following conditions. Temperature of iron-tip : 400 °C max. Soldering iron wattage : 50W max. Soldering time : 3.5s max. 7. BONDING, RESIN MOLDING AND COATING In case of bonding, molding or coating this product, verify that these processes do not affect the quality of capacitor by testing the performance of the bonded, molded or coated product in the intended equipment. In case of the amount of applications, dryness / hardening conditions of adhesives and molding resins containing organic solvents (ethyl acetate, methyl ethyl ketone, toluene, etc.) are unsuitable, the outer coating resin of a capacitor is damaged by the organic solvents and it may result, worst case, in a short circuit. The variation in thickness of adhesive, molding resin or coating may cause a outer coating resin cracking and/or ceramic element cracking of a capacitor in a temperature cycling. 8. TREATMENT AFTER BONDING, RESIN MOLDING AND COATING When the outer coating is hot (over 100 ℃) after soldering, it becomes soft and fragile. So please be careful not to give it mechanical stress. Failure to follow the above cautions may result, worst case, in a short circuit and cause fuming or partial dispersion when the product is used. 9. OPERATING AND STORAGE ENVIRONMENT The insulating coating of capacitors does not form a perfect seal; therefore, do not use or store capacitors in a corrosive atmosphere, especially where chloride gas, sulfide gas, acid, alkali, salt or the like are present. And avoid exposure to moisture. Before cleaning, bonding, or molding this product, verify that these processes do not affect product quality by testing the performance of a cleaned, bonded or molded product in the intended equipment. Store the capacitors where the temperature and relative humidity do not exceed -10 to 40 °C and 15 to 85%. Use capacitors within 6 months after delivered. Check the solderability after 6 months or more. 10.
