Discover the power of MML™ technology

The best performing film capacitors on the market with the highest energy density ever!

Exxelia's revolutionary MML™ ultra-high energy density Film Capacitors are a game changer in the industry due to their unparalleled energy density of 400 J/dm3. This allows for a significant reduction in size and weight in comparison to traditional Polypropylene or Polyester dielectrics, as well as an increased operating temperature of up to 140°C and protection against transient voltage.

Not only do MML™ capacitors offer a large flexibility in design, allowing for low profile configurations, but they have also been tested in actual cases for controls and DC-Links functions in aircraft applications and have shown a reduction in size and weight of about 50% compared to other film technologies.

Furthermore, when compared to MLCCs, MML™ capacitors have demonstrated a reduction in weight of between 70% to 90%, with no capacitance derating with voltage applied and a low drift of less than 5% across the temperature range. Applications that previously required clusters of stacked MLCCs can now be replaced by a single MML™ unit of similar size, with the added reliability that film dielectric offers.

The exceptional properties of Exxelia's new MML™ capacitors make them suitable for a wide range of applications including power supplies, DC-links, AC/DC/AC power converters, charge/discharge or power generation functions of commercial/military aircraft, satellite platforms and payloads, launchers, defibrillators, downhole tools and any other applications that require confined electronics.
