- KYOCERA AVX launches advanced FFLK capacitors for EV and industrial DC filtering applications.
- Patented self-healing film technology enhances reliability and prevents catastrophic failures.
On April 20, KYOCERA AVX introduced a new range of traction-grade FFLK series DC filtering film capacitors engineered to deliver extended operational life in high-demand environments such as electric vehicle traction systems and industrial motor control applications. These capacitors are designed to meet the growing reliability requirements of electrified mobility and power electronics systems, where consistent performance under high voltage stress is critical for system efficiency and durability.
Design Architecture and Material Composition
The FFLK series incorporates cylindrical aluminum housings combined with either dry or wet metallized polypropylene film technology. The units are built using UL94 V-0 rated self-extinguishing thermoplastic resin to enhance safety performance under extreme conditions. Connectivity options include female M6 or M10 connectors as well as male M8 or M20 connectors, offering flexibility for various integration requirements. Additionally, each capacitor is equipped with a mechanical mounting bolt, ensuring secure installation in vibration-prone automotive and industrial environments.
Self-Healing Dielectric Technology Enhances Reliability
A defining feature of the FFLK series is its proprietary dielectric film technology, originally developed and patented by KYOCERA AVX in 1976. This specialized film enables controlled self-healing behavior by isolating dielectric breakdown events. When a fault occurs, the adjacent electrode material vaporizes, effectively neutralizing the defect. This mechanism prevents short circuits, eliminates the risk of catastrophic failure, and ensures continued normal operation of the capacitor, significantly improving long-term reliability.
Wide Range of Configurations for Diverse Applications
The newly launched series is available in multiple configurations, offering a broad selection of voltage ratings, capacitance values, and physical sizes. The cylindrical casings range from 130 mm to 340 mm in height and 85 mm to 116 mm in diameter, enabling compatibility with different system architectures. This flexibility supports deployment across a wide range of use cases, from compact EV platforms to large-scale industrial motor systems requiring robust DC filtering performance.
Global Manufacturing and Corporate Background
Headquartered in Fountain Inn, South Carolina, in the United States, KYOCERA AVX operates as a subsidiary of Kyocera Corp, based in Japan. The company continues to expand its portfolio of advanced electronic components, supporting the global transition toward electrification and high-efficiency power systems.
