Utilization under unusual environment (deoxidation-gas and corrosion-gas and others) is
strictly prohibited because of a possible deterioration of the performance.
Twisting boards may cause direct damage to the parts. The boards must be handled in
minimum stress.
Only reflow soldering is applicable.
Do not touch the parts by soldering iron to avoid chipping problem.
The product side is not insulation construction.
Avoid the pattern layout designing under/near the product.
If you use the product exceeding the max. working voltage, it may be a cause
of the short mode failure
