Aluminum Organic Capacitor (AO-CAP)
A700 Polymer Aluminum, 2 – 25 VDC
Soldering Process
KEMET’sfamiliesofsurfacemountcapacitorsare
compatible with wave (single or dual), convection, IR,
orvaporphasereowtechniques.Preheatingofthese

passes at these conditions.
Please note that although the X/7343–43 case size can
withstandwavesoldering,thetallprole(4.3mmmaximum)
dictates care in wave process development.
Hand soldering should be performed with care due to the
dicultyinprocesscontrol.Ifperformed,careshouldbe
taken to avoid contact of the soldering iron to the molded
case. The iron should be used to heat the solder pad,
applying solder between the pad and the termination, until
reowoccurs.Oncereowoccurs,theironshouldbe
removed immediately. “Wiping” the edges of a chip and
heating the top surface is not recommended.
