To comply with recommended conditions for
reflow soldering. Pre-heating shall be done
at 150 ~ 200°C and for 60 ~ 180 sec.
Peak temp. is 265°C, within 10 sec.
Measurement for solder temperature profile
shall be made at a point on the terminal
nearest where the terminals protrude through
the soldering side of PC board.

ESR measurements should be made at a point on the terminal nearest the end seal of the capacitor.
Conditioning : If there is doubt about the measured result, measurement should be made again after the rated voltage is applied for 120 minutes
at the temperature of 105°C.
