Polypropylene Pulse/High Frequency Capacitors
A70, Single Metallized Polypropylene Film, Axial
Overview
Applications
The A70 Series is constructed of metallized polypropylene
film 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.
Typical applications include temperature compensation
circuits, timing, oscillator circuits, power factor correction,
and coupling capacitors in switched mode power supply
(SMPS) applications. Not suitable for across-the-line
application (see Suppressor Capacitors).

Film Capacitors – Polypropylene Pulse/High Frequency Capacitors
A70, Single Metallized Polypropylene Film, Axial
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 profiles 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.
Reflow soldering is not recommended for through-hole film capacitors. Exposing capacitors to a soldering profile 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 profile 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 reflow 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 flow 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 profile for selective soldering is similar to the double wave flow 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 flow soldering. Great care must be taken so that the parts are not overheated.
