    MML Technology - Exceptional properties in one capacitor

    We would like to use this chance to acquaint you with the nearly groundbreaking MML™ Technology and its impressive characteristic. This product unites all positive features regarding weight, capacity, and performance and is set to be a major factor in upcoming progress and unlock new possibilities within the technological framework.

    Abstract Miniature Micro-Layer Technology

    01

    What is MML™
    technology

    MML™ is a revolutionary new technology that provides the highest capacitance per volume in film capacitors available on the market and can replace other technologies.
    02

    MML™ and it's technical
    performance

    Outstanding size and weight reduction compared to other technologies or higher capacity and performances are only an excerpt of the technical performances.
    03

    MML™ vs. other
    technologies

    Higher energy density & improved performance, as well as favorable performance characteristics compared to other film technologies, give more scope for system architecture.
    04

    compatibility &
    applications of MML™

    MML™ technology can easily meet and exceed the capacitance and packaging requirements for ex. Markets like Commercial Aircraft ASCU, Motor control in eVTOL, Space, Defence or other.

    01| What is MML ™ technology
