Discover the power of MML™ technology

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

Condensateur MML

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.

Our presence at Electronica 2022

Aircraft & Space Embedded Products cluster, bringing together components that can be mounted on a satellite, radar or aircraft, we were ready to introduce two innovations that are particularly well suited to the challenges of the aviation of the future and the objectives of decarbonisation of the air. Its latest film capacitor innovation called MML™ (named after its "Miniature Micro-Layer" dielectric) shows an energy density up to 4 times higher than other film dielectrics. MML® technology makes power capacitors smaller, lighter and compatible with higher temperatures, and is therefore particularly suitable for DC-Link, decoupling & charge-discharge applications. Alongside MML™ components, we presented the latest innovations in magnetic components, saving up to 40% in weight and 20% in volume while dissipating more power, some of which have been designed for eVTOL applications, as well as the CCM & Dual Active Bridge multi-output transformers. Rail & Energy Exxelia showed Alcon capacitors for the first time at its Rail & Energy cluster. Alcon is one of India&#39;s leading designers and manufacturers of standard and customised aluminium electrolytic and film capacitors for niche markets. Alcon supplies many of the components used in trains, electrical charging stations and power generation systems. Exxelia&#39;s film and ceramic capacitors for signalling systems, as well as current and instrument transformers, and resistors was presented on display.   Medical​​ Exxelia Micropen & Exxelia Ohmcraft components was showcased at Electronica for the very first time with a unique offering for the medical sector. Indeed, Exxelia Micropen&#39;s unique additive printing technology is widely used for disposable medical equipment such as endotracheal tubes or surgical ablation tools, and high voltage resistors are used in laboratory equipment such as mass spectrometers or thermal cyclers.
