Manual Soldering Recommendations
Following is the recommendation for manual
soldering with a soldering iron.
The soldering iron tip temperature should
besetat350°C(+10°Cmaximum)withthe
soldering duration not to exceed more than 3
seconds.

Soldering Process
The implementation of the RoHS directive has resulted in the selection of SnAgCu (SAC) alloys or SnCu alloys as primary solder.
Thishasincreasedtheliquidustemperaturefromthatof183°CforSnPbeutecticalloyto217–221°Cforthenewalloys.Asa
result,theheatstresstothecomponents,eveninwavesoldering,hasincreasedconsiderablyduetohigherpre-heatandwave
temperatures.Polypropylenecapacitorsareespeciallysensitivetoheat(themeltingpointofpolypropyleneis160–170°C).
Wavesolderingcanbedestructive,especiallyformechanicallysmallpolypropylenecapacitors(withleadspacingof5mmto
15mm),andgreatcarehastobetakenduringsoldering.TherecommendedsolderprolesfromKEMETshouldbeused.Please
consultKEMETwithanyquestions.Ingeneral,thewavesolderingcurvefromIECPublication61760–1Edition2servesasasolid
guideline for successful soldering. Please see Figure 1.
Reowsolderingisnotrecommendedforthrough-holelmcapacitors.Exposingcapacitorstoasolderingproleinexcessofthe
abovetherecommendedlimitsmayresulttodegradationorpermanentdamagetothecapacitors.
Do not place the polypropylene capacitor through an adhesive curing oven to cure resin for surface mount components. Insert
through-holepartsafterthecuringofsurfacemountparts.ConsultKEMETtodiscusstheactualtemperatureproleintheoven,
if through-hole components must pass through the adhesive curing process. A maximum two soldering cycles is recommended.
Pleaseallowtimeforthecapacitorsurfacetemperaturetoreturntoanormaltemperaturebeforethesecondsolderingcycle.
