DEH Series Specifications and Test Methods
The lead wire should be immersed into the melted solder of
350±10°C up to about 1.5 to 2mm from the main body for
3.5±0.5 sec.
Pre-treatment:
Post-treatment:
Measurement order:
First the capacitor should be
stored at 120+0/-5°C for
60+0/-5 sec.
Then, as in figure, the lead wires
should be immersed in solder of
260+0/-5°C up to 1.5 to 2.0mm
from the root of terminal for
7.5+0/-1 sec.
Pre-treatment:
Post-treatment:
Measurement order:
The capacitor should be subjected to 5 temperature cycles.
