Test Method
The lead wire of the capacitor is dipped into molten solder for
5±0.5 seconds. The depth of immersion is up to 1.5 mm
(+5/−0 mm) from the root of lead wires.
Solder Temperature: Lead free solder (Sn-3Ag – 0.5Cu)
245°C ±5°C.
As shown in the figure below, the lead wires are immersed in
molten solder up to 1.5 mm (+5/−0 mm) from the end of the
epoxy meniscus (root of lead wire).
Duration/Solder Temperature: 3.5±0.5 seconds/350°C ±10°C or

Pre-treatment: Capacitor is stored at 85°C ±2°C for 1 hour and
then placed at room condition¹ for 24 ±2 hours before initial
measurements.
Post-treatment: Capacitor is stored for 1 to 2 hours at room
condition¹.
Capacitor is stored at 120°C +0/−5°C for 60 +0/−5 seconds.
Then, as shown in the figure below, the lead wires are immersed
in molten solder up to 1.5 mm (+5/-0mm) from the end of the
epoxy meniscus (root of lead wire).
