Film Capacitors
Available from APC Hi-Rel, AVX produces a full range of film dielectric components – from low power SMD solutions for the commercial and automotive industry, to medium and high power film capacitors suited to all power electronic applications over a voltage range spanning 75V volts up to 100 kV. Our technology includes both dry and oil impregnated designs, based on polyester and polypropylene dielectrics. Applications range from DC filtering, semiconductor protection and tuning, to discharge and high energy storage.

High Power Film Capacitors
AVX’s high power capacitors use high purity oil impregnation to achieve superior energy density in a compact capacitor design. They offer a high voltage range of 1.2kV – 100kV, with standard and custom terminal options. Our proprietary Controlled Self-Healing technology enhances the lifetime performance of power film capacitors. Controlled self-healing enables the capacitor to operate continually without catastrophic failure by immediately insulating any overstress sites that may occur in the dielectric layer. During operation, the capacitance will reduce slightly as a result of the controlled self-healing mechanism; capacitors are designed to lose no more than 2% of the original value over their operating lifetime at full voltage and temperature.
Available in the following capacitors:
Medium Power Film Capacitors
AVX medium power film capacitors incorporate a dry segmented and non-segmented metallized polypropylene or polyester dielectric. The segmentation provides controlled self-healing, designed to achieve very high dielectric strength and avoid catastrophic failure. With AVX controlled self-healing technology, the segmented capacitors comprises several million elements, each protected by “fuse gates”. During operation, any dielectric breakdown becomes insulated locally, minimizing the risk of short circuit and the capacitor continues functioning normally.
Available in:
- AC Filtering, DC Filtering, Discharge, Protection, Tuning
SMD Chip Film Capacitors
The self healing property of film dielectric provides an open failure mode capacitor with excellent reliability. The intrinsic characteristic of film provides a capacitor which exhibits low DC Bias, excellent thermal behavior, no Piezoeffect and low ESR,ESL and dissipation factor. AVX’s SMD film capacitors are available in three dielectrics: PEN, PET-HT, and PPS, and in case sizes ranging from 1206 to 6054. Customised designs available on request.

Energy Storage Discharge Capacitors
DISFIM Products
AVX’s disfim capacitors, from APC Hi-Rel, are designed for energy storage and discharge applications. Controlled self-healing enables the capacitor to operate continually without catastrophic failure by immediately insulating any over-stress sites that may occur in the dielectric layer. During operation, the capacitance will reduce slightly as a result of the controlled self-healing mechanism; discharge capacitors are designed to lose no more than 5% of the original value over their operating lifetime at design voltage and temperature.
Features:
- Voltage range from 2kV to 75kV
- Maximum energy per capacitor: 150kJ
- Specific energy up to 2000J/l
- Lifetime up to several tens of millions of shots
- Stray inductance’s from 50nH to 500nH
Applications: Power laser, electromagnetic and ETC guns, high voltage supplies, marx generators, cable failure detectors, welding machine

Hybrid and Electric Vehicle Capacitors
Hybrid and Electric Vehicle Capacitors – FHC1 & FHC2 Series
The FHC 1 and 2 products assure reliable operation for long lifetimes due to unique controlled self-healing technology. The FHC 1 & 2 provide a standard option for DC link capacitors used in DC filtering between rectifier and inverter in automotive applications. The series uses a dry-wound (non-oil-filled) segmented metallised polypropylene, specially treated to have a very high dielectric strength in operating conditions up to 115°C.
Features:
- Controlled self-healing property
- Custom designs (mechanical/electrical)
- Alternative to electrolytic, mica, film foil and ceramic
- Total safety, reliability and soft end of lifetime due to controlled self-healing
- Dry solution, no drying out
- Standard solution
Applications: DC-link capacitor in EV/HEV, select motor drives, renewable energy (wind, solar, power grid), power electronics that need high reliability, WBG technology
