R-T CHARACTERISTICS
APPLICATION NOTES
■
Utilization under unusual environment (reduction-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.
