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'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'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'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.  

Exxelia revolutionary MML™ ultra-high energy density Film Capacitors

MML™ is a revolutionary new technology that provides the highest capacitance per volume in film capacitors available on the market.    Why is it a game changer? Because an unparalleled energy density of 400 J/dm3 allows for a tremendous reduction in size and weight compared to traditional Polypropylene or Polyester dielectrics, together with an increased operating temperature up to 140 °C and transient voltage protection.   Besides, MML™ capacitors offer a large flexibility in design, easily allowing low profile configurations. Several 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.  The comparative picture with MLCC is even more flattering, as it 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. Applications using clusters of stacked MLCCs can now be replaced by a single MML™ unit of similar size, 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. Samples are readily available on request. Features & Benefits : Miniaturization of the function : Up to 50% size reduction vs other film technologies ; matching footprint with stacked MLCC Lightweight : 50% lighter vs other film technologies ; 80 to 90% lighter than ceramic No capacitance derating in voltage, stable in temperature (<5% drift through the temperature range) Capacitance from 1μF to 1000μF  Voltages from 50V to 1000V  Operating Temperature -55 °C to +140 °C Highly customizable
