KEMET Organic Capacitor (KO-CAP
®
) – Automotive Grade
T591, T598, T597, and T599 High Humidity and High Temperature Automotive Grade Polymer Electrolytic, 2.5 - 50 VDC
Soldering Process
KEMET’sfamiliesofsurfacemountcapacitorsare
compatiblewithwave(singleordual),convection,IR,
orvaporphasereowtechniques.Preheatingofthese
components is recommended to avoid extreme thermal
stress.KEMET'srecommendedproleconditionsfor
convectionandIRreowreecttheproleconditionsofthe
IPC/J–STD–020Dstandardformoisturesensitivitytesting.
Thedevicescansafelywithstandamaximumofthreereow
passes at these conditions.
PleasenotethatalthoughtheX/7343–43casesizecan
withstandwavesoldering,thetallprole(4.3mmmaximum)
dictates care in wave process development.
Handsolderingshouldbeperformedwithcareduetothe
dicultyinprocesscontrol.Ifperformed,careshouldbe
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
reowoccurs.Oncereowoccurs,theironshouldbe
removedimmediately.“Wiping”theedgesofachipand
heatingthetopsurfaceisnotrecommended.
