Printed Circuit Board Mount Power Film Capacitors
C4AK, Radial, 2 or 4 Leads, 450 – 1,000 VDC, for DC Link
(Automotive Grade) - 125°C with Long Life and High Voltage
Overview
Applications
The C4AK capacitor is a new polypropylene material
metallized film capacitor with a rectangular, plastic box-type
design (black color) filled with resin, and uses 2 or 4 tinned
wires.
Typical applications include DC filtering, DC link, power
electronics, energy storage, renewable energy grid interface,
motor drives, and automotive applications.
Automotive grade devices meet the demanding Automotive
Electronics Council's AEC-Q200 qualification requirements
with longer life at 125°C (higher voltage derated) and 135°C.
Benefits
• High voltage & long life at 125°C
• Voltage derated at 135°C
• THB 85°C/85% R.H. at VR for 1,000 hours
• Low Halogen Content according to JS709C

Environmental Compliance
As a leading global supplier of electronic components and an environmentally conscious company, KEMET continually
aspires to improve the environmental effects of our manufacturing processes and our finished electronic components.
In Europe (RoHS Directive) and in some other geographical areas such as China (China RoHS), legislation has been enacted
to prevent or otherwise limit the use of certain hazardous materials, including lead (Pb), in electronic equipment. KEMET
monitors legislation globally to ensure compliance and endeavors to adjust our manufacturing processes and/or electronic
components as may be required by applicable law.

Environmental Compliance cont.
For military, medical, automotive, and some commercial applications, the use of lead (Pb) in the termination is necessary
and/or required by design. KEMET is committed to communicating RoHS compliance to our customers. Information related
to RoHS compliance will be provided in data sheets and using specific identifiers on the packaging labels.
All KEMET power film capacitors are RoHS compliant.

Materials & Environment
The selection of raw materials that KEMET uses for the production of its electronic components is the result of extensive
experience. KEMET directs specific attention toward environmental protection. KEMET selects its suppliers according to
ISO 9001 standards and performs statistical analyses on raw materials before acceptance for use in manufacturing our
electronic components. All materials are, to the best of KEMET’s knowledge, non-toxic and free from cadmium; mercury;
chrome and compounds; polychlorine triphenyl (PCB); bromide and chlorinedioxins bromurate clorurate; CFC and HCFC;
and asbestos.
Dissipation Factor
Dissipation factor is a complex function involved with capacitor inefficiency. The tgδ may vary up and down with increased
temperature. For more information, refer to Performance Characteristics.
Sealing
Hermetically Sealed Capacitors
As the temperature increases, the pressure inside the capacitor increases. If the internal pressure is high enough, it can
cause a breach in the capacitor. Such a breach can result in leakage, impregnation, filling fluid, or moisture susceptibility.
Barometric Pressure
The altitude at which hermetically sealed capacitors are operated controls the capacitor's voltage rating. As the barometric
pressure decreases, the susceptibility to terminal arc-over increases. Non-hermetic capacitors can be affected by internal
stresses due to pressure changes. These effects can be in the form of capacitance changes, dielectric arc-over, and/or low
insulation resistance. Altitude can also affect heat transfer. Heat that is generated in an operation cannot be dissipated
properly, and high RI2 losses and eventual failure can result.

C4AK, Radial, 2 or 4 Leads, 450 – 1,000 VDC, for DC Link (Automotive Grade) - 125°C with Long Life and High Voltage
Soldering Process
The implementation of the RoHS directive has resulted in the selection of SnAuCu (SAC) alloys, or SnCu alloys, as the primary
solder material. This has increased the liquidus temperature from 183°C for a SnPb eutectic alloy to 217 – 221°C for 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 – 15 mm),
and great care must be taken during soldering. The recommended solder profiles from KEMET should be used. Contact 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. See Figure 1.
Reflow soldering is not recommended for through-hole film capacitors. Exposing capacitors to a soldering profile in excess of the
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 curing the surface mount parts. Contact 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.
Allow time for the capacitor surface temperature to return to normal 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 pre-heated 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. 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 with a time from 3 – 10 seconds. In selective soldering, the risk of
overheating is greater than in double wave flow soldering, and great care must be taken so that the parts do not overheat.
