Overview
TheA72Seriesisconstructedofpolypropylenelmand
metalfoilormetallizedlmandmetalfoilwithaxialleads
oftinnedwire.Theaxialleadsareelectricallyweldedto
the metal layer on the ends of the capacitor winding. The
capacitor is encapsulated in a polyester tape wrapping case
with thermosetting resin material. Two different winding
constructions are used depending on voltage parameters.
Please see the Performance Characteristics for more
information.
Applications
Typical applications include resonant circuit, high frequency
mediumtoheighcurrent,silicon-controlledrectier
(SCR and IGBT) as well as applications with high voltage
and medium to high current.
Not suitable for across-the-line application (see Suppressor
Capacitors).

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 recommended limits may result in 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.

Selective Soldering Recommendations
Selectivedipsolderingisavariationofreowsoldering.Inthismethod,theprintedcircuitboardwiththrough-hole
componentstobesolderedispreheatedandtransportedoverthesolderbathasinnormalowsolderingwithouttouching
the solder. When the board is over the bath, it is stopped and pre-designed solder pots are lifted from the bath with molten
solder only at the places of the selected components, and pressed against the lower surface of the board to solder the
components.
Thetemperatureproleforselectivesolderingissimilartothedoublewaveowsolderingoutlinedinthisdocument,
however, instead of two baths, there is only one bath with a time from 3 to 10 seconds. In selective soldering, the risk of
overheatingisgreaterthanindoublewaveowsoldering.Greatcaremustbetakensothatthepartsarenotoverheated.
