5. VIBRATION AND IMPACT
Do not expose a capacitor or its leads to excessive shock or vibration during use.
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 chip : 400 ℃ max.
Soldering iron wattage : 50 W max.
Soldering time : 3.5 s 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.
