aution (Storage and operating condition)
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
are likely to be 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 degrees centigrade and 15 to 85 % R.H.
Use capacitors within 6 months.
 Caution (Soldering and Mounting)
1. Vibration and impact:
Do
not expose a capacitor or its leads to excessive shock or vibration during use.
2. 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 these capacitor with a soldering iron, it should be performed in following conditions.
3. Cleaning (ultrasonic cleaning):
To perform ultrasonic cleaning, observe the following conditions.
Rinse bath capacity: Output of 20 watts per liter or less.
Rinsing time: 5 min maximum.
Do not vibrate the PCB/PWB directly.
Excessive ultrasonic cleaning may lead to fatigue destruction of the lead wires.
Temperature of iron-tip: 400 degrees C. max.
Soldering iron wattage: 50W max.
Soldering time: 3.5 sec. max.
 Caution (Handling)
V
ibration and impact
Do not expose a capacitor or its leads to excessive shock or vibration during use.
Failure to follow the above cautions may result, in worst case, in a short circuit and cause
fuming or partial dispersion where the product is used.
