KEMET Organic Capacitor (KO-CAP
®
)
T52x/T530 Polymer Electrolytic Capacitors
Soldering Process
The KEMET 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.

Storage
All KO-CAP Series are shipped in moisture barrier bags (MBBs) with desiccant and humidity indicator card (HIC). These
parts are classied as MSL3 (Moisture Sensitivity Level 3) per IPC/JEDEC J–STD–020 and packaged per IPC/JEDEC
J–STD–033. MSL3 species a oor time of 168H at 30°C maximum temperature and 60% relative humidity. Unused
capacitors should be sealed in a MBB with fresh desiccant.
The calculated shelf life in a sealed bag would be 12 months from a bag seal date in a storage environment of < 40°C and
humidity < 90% RH. It should be 24 months from a bag seal date in a storage environment of < 30°C and humidity < 70% RH.
If baking is required, refer to IPC/JEDEC J–STD–033 for bake procedure.
