Exxelia Revolutionary MML™ Ultra-High Energy Density Film Capacitors

MML™ is an advanced new technology that provides the highest capacitance per volume in film capacitors compering to all other existing film solutions.

The MML™ capacitors allow very low-profile configurations and offer high flexibility in the design.

The technology offers a tremendous reduction in size and weight compared to traditional Polypropylene or Polyester dielectrics, due to the unparalleled energy density of 400 J/dm3, together with an increased operating temperature up to 140 °C and transient voltage protection.

Compering the MML technology with MLCC demonstrates between 70% to 90% reduction in weight, while showing no capacitance derating with voltage applied and a low drift < 5% through the temperature range.

case studies have been conducted on actual cases of controls and DC-Links functions for aircraft applications. All have shown about 50% reduction in size and weight compared to other film technologies.

A single MML™ unit can replace a stacked MLCC’s used in different applications. with all the increased reliability that film dielectric offers.

With such outstanding properties, Exxelia new MML™ capacitors are perfectly suitable for 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 applications of confined electronics.

Features & Benefits:

  • Lightweight: 50% lighter vs other film technologies; 80 to 90% lighter than ceramic
