KYOCERA AVX Launches Traction-Grade DC Filtering Capacitors

KYOCERA AVX, a well-established global leader in advanced electronic components, has recently introduced the FFLK series of traction-grade DC filtering capacitors. This new series is strategically developed for a range of demanding applications such as industrial motor control and electric vehicle (EV) traction systems, which often encounter high power, shock, vibration, and temperature stresses.

Key Features and Advantages

The FFLK series boasts several notable features making it stand out in the competitive market of DC filtering solutions. Firstly, they are designed to achieve superior volumetric efficiency, which translates to higher current handling capabilities within compact case sizes compared to both KYOCERA AVX’s existing solutions and those from rival suppliers. This inherently improves system design flexibility, particularly in scenarios where space is at a premium.

These capacitors are equipped with cylindrical aluminum forms, utilizing dry or wet metallized polypropylene films. They come with UL94 V-0 rated thermoplastic resins, ensuring safety and reliability in operation. Notably, they also offer various connection options via available M6, M10, M8, and M20 connectors, supplemented by a mechanical mounting bolt for enhanced installation options.

A significant aspect of the FFLK series is the controlled self-healing capability of the dielectric film. Originally developed and patented by KYOCERA AVX in 1976, this unique feature isolates dielectric breakdowns and neutralizes them by vaporizing surrounding electrodes, averting potential short circuits and serious failures while allowing for standard operation barring a gradual capacitance decline over time. This makes the FFLK series an exceptionally reliable solution that outperforms many competitive DC film capacitors.

Diverse Application Range

The applications for the FFLK series capacitors are notably robust, encompassing high-power industrial motor controls and electric vehicle traction systems. They have been crafted to perform effectively even under extreme conditions often found in industrial environments. For example, variants using dry segmented metallized polypropylene film are rated from 900VDC to 1,900VDC, while those with wet film are rated up to 3,800VDC, providing developers with ample flexibility. Capacitor values range from 25µF to 3,020µF, offering customization to meet various system requirements.

Furthermore, these components have been designed to comply with international standards, including IEC, UL, EN, and RoHS regulations. With a lifespan projected at around 100,000 hours—when used under specified voltage, temperature limits, and conditions—the FFLK series ensures longevity in performance, reducing the need for frequent replacements in critical applications.

Market Positioning and Impact

KYOCERA AVX's Product Marketing Manager Perrin Hardee succinctly highlighted the advantages of the FFLK series by stating that they combine size, cost-efficiency, power handling, durability, safety, and specification coherence into a singular product line. The capacitors allow for a full range of voltage performance under a unified part number, thus addressing many common challenges faced by engineers in the field.

Furthermore, as the EV market expands, the demand for reliable and efficient components like those in the FFLK series is set to rise. Their ability to withstand higher levels of surge voltage while maintaining lower Equivalent Series Resistance (ESR) positions them as a superior choice over conventional aluminum electrolytic capacitors in traction applications, ensuring enhanced energy efficiency and performance longevity.

To learn more about the new FFLK series of DC filtering capacitors, individuals and businesses can access datasheets and educational materials directly from the KYOCERA AVX website or order products through distributors like DigiKey or Mouser Electronics. For tailored requirements, customers can reach out to dedicated representatives across different global regions, ensuring that they receive optimal solutions for their specifications.

Conclusion

The introduction of the FFLK series emphasizes KYOCERA AVX's commitment to fostering technological advancement through innovative electronic solutions. By enabling more efficient and reliable operations in demanding applications like industrial motor control and electric vehicle traction systems, these capacitors significantly contribute to the evolution of modern electronics, supporting a sustainable and efficient future.
