Exxelia & Ariane 6
Several of our ESA QPL certified components such as our CCM and SESI ranges are notably on board, as well as two very special custom designed film capacitors
In January 2022, the upper and lower stages of Ariane 6 have arrived on the launch complex of the Guiana Space Center.

Magnetic Components based on Adaptive CCM Technology Exxelia designed CCM technology to respond to the growing interest of electronic engineers for inductors and transformers with multiple outputs, high power density and reduced footprint. Qualified for aeronautic and space applications, the CCM product line features terrific robustness. The monolithic design provides high mechanical performance, proven by the successfully testing in accordance with MIL-STD-202 (methods 213 and 204). The series offers five different sizes, allowing optimized component design in a pick-and-place surface mount (SMD) package. Through-hole (TH) packages are also available upon request. The CCM series is particularly flexible with a number of pins options available, from 2×6 pins for the smallest package, up to 2×10. CCM transformers and inductors can operate over a wide temperature range with a minimal temperature of -55° C. The standard thermal grade of the technology is 140° C. Thanks to the technology design, the thermal resistance is 30% lower than standard industrial components. The epoxy molding protecting the winding ensures a lower temperature gradient and a better heat dissipation. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Component materials meet UL 94-V0 rating. Cost-effective Common-mode Chokes Qualified for Aerospace Exxelia designed this extensive and cost-effective range to be an easy commercial (COTS) solution for aerospace, defense, and other high-reliability applications. The TCM series is available in a through-hole package for horizontal or vertical mounting. TCM chokes are offered with inductances from 0.7 mH to 47 mH under rated currents from 0.3 to 4.0 A. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Excellent thermal properties allow the series to operate from -55° C to +125° C. The high mechanical performance of the component materials (all meeting to UL94 V0 rating) makes TCM a perfect fit for aviation, defense and transportation industries.
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
