Printed Circuit Board Mount Power Film Capacitors
C4C, Axial Round, 850 – 3,000 VDC/450 – 750 VAC
Overview
Applications
The C4C capacitor is a polypropylene metallized film and
polyester double-metallized foil capacitor with a polyester
tape wrapping filled with resin, and uses tinned
copper wires.
Typical applications include snubber, clamping, resonance,
coupling/decoupling, pulse, and blocking.
Benefits
• Self-healing
• Low loss
• High ripple current
• High contact reliability
• Suitable for high frequency applications
• PP metallized and PET double-sided metallized foil

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.
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.

Power and AC Film Capacitors – Printed Circuit Board Mount Power Film Capacitors
C4C, Axial Round, 850 – 3,000 VDC/450 – 750 VAC
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.

First wave
Temperature (°C)
The implementation of the RoHS Directive has required the
selection 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 components,
even in wave soldering, has increased considerably due
to higher pre-heat and wave temperatures. Polypropylene
capacitors are especially sensitive to heat (melting point
of polypropylene is 160 – 170°C). Wave soldering can be
destructive especially for mechanically small polypropylene
capacitors (lead spacings 5 – 10 mm) and great care must
be taken during soldering. The solder profiles from KEMET
are highly recommended. You may also refer to the wave
soldering curve from IEC Publication 61760–1 Edition 2.
Please consult KEMET with any questions.
