Soldering Recommendations:
When soldering this component to a PC board, the
solder heat resistance specification of the capacitor
must not be exceeded.
Subjecting this component to excessive heating could
melt the internal solder junction and may cause
thermal stress that can crack the ceramic element.
In order to keep a sufficient distance between solder
wave and the capacitor element we recommend to
use capacitor styles with crimped leads.
