JUICE Mission to Jupiter: Exxelia components ready to withstand extreme space conditions

On April 14, 2023, the JUICE (JUpiter ICy moons Explorer) mission will launch to explore the icy moons of Jupiter. It is an incredible event that has been long-awaited by astronomy enthusiasts. But did you know that components from Exxelia are on board this satellite?

Mission Juice ESAExxelia is known for the quality and reliability of its products, making it a popular choice for space missions.

Exxelia components are used in many embedded systems on board the JUICE mission, including capacitors (High Voltage C Series X7R & TCK Series X7R, CEC Series NP0, Polyester PET PM 948) and magnetics (Inductors MPCI, CMC, SESI inductors, Common mode choke and specific transformers). They have been carefully designed and tested to withstand the extreme conditions of space.

Exxelia has been working closely on this project for more than 10 years, notably on the GALA (GAnymede Laser Altimeter) and MAJIS (Moon and Jupiter Imaging Spectrometer) instruments.

 

Conditions in space are extreme, with high levels of radiation, drastic temperature variations, and intense vibrations. Exxelia components have been designed to withstand these conditions, providing consistent and reliable performance throughout the mission.

 

1st European mission to Jupiter. Focusing on its icy moons and evaluating the potential for habitable worlds.

The JUICE mission is an ambitious undertaking that aims to explore Jupiter's icy moons and study their composition and history. This mission will help us better understand the evolution of the solar system and search for signs of life beyond Earth.

Exxelia expose à PCIM

Two new ranges of MIL-qualified tantalum capacitors: MIL39006/22 & MIL39006/25 The recently introduced ranges of MIL-qualified tantalum capacitors will be showcased on the company booth. MIL 39006/22 and MIL 39006/25 respectively equivalent to CLR79 and CLR81 types featuring hermetically sealed cylindrical tantalum cases and axial leads are available in T1, T2 T3 and T4 cases with extended capacitance and voltage ratings. MIL 39006/22 is qualified for voltages from 6V to 125V and provides from 1200µF @6V to 56µF @125V. MIL 39006/25 is qualified for voltages from 25V to 125V and delivers from 680µF @25V to 82µF @125V. Both ranges combine high energy density with a large operating temperature range of -55°C - +125°C and H vibrations and shocks resistance. PHM 912, very high energy density film capacitors PHM 912 is a new standard series of film capacitors based on a novel metallized plastic film dielectric from Dupont Teijin®. The PHM 912 capacitors are specifically designed for DC filtering or energy storage. Very stable in both temperature and frequency, they are well-adapted for applications such as filtering in H.F. switch mode power supplies, DC link or decoupling. The range can withstand temperatures up to 155°C and up to 175°C in custom version. With their high energy density, these capacitors allow highly integrated power filters. Their compact construction results in a low ESR, ESL and excellent high current and frequency performances. The series provides 250V @68µF and 0,27µF @1000V.  The PHM 912 series makes significant advances over previous technologies by combining the benefits of excellent temperature resistance with superior energy densities, making it one of the most compact capacitors on the market. Felsic HV, long lifetime and high voltage screw terminal aluminum electrolytic capacitor The Felsic HV family of aluminum electrolytic screw terminal capacitors provides great performances in energy density combined with ultra-long lifetime. For instance, 6 800µF @450V fit into a volume of Ø77x220mm  and can withstand 200,000 hours between 0 to 70° under 37Amps, which makes them the perfect choice for use in rolling stock traction systems or the CVS. The family also has one of the lowest ESR of its class with less than 10m0hms in most cases. Products are available for voltages from 160 to 450Vdc, and offer capacitance values from 1500μF up to 47 000μF offering the best compromise between reliability and compactness.

X-59 QueSST de la NASA : Exxelia est à bord

Si le programme tient ses promesses, il pourrait permettre l’émergence d’avions de transport supersoniques capables de voler au-dessus des terres, sans les limitations imposées au Concorde en son temps. Pour ce projet, Exxelia produit principalement des bobines en provenance de nos sites USA. Nos composants sont à destination du moteur de l’avion.     Avec son nez allongé, ses ailes “bossues” et ses petites surfaces portantes dispersées, le X-59 ne ressemble à aucun autre avion. Une configuration exceptionnelle pour des capacités exceptionnelles. Crédits: NASA     Il volera à une vitesse de 1,5 Mach (1,5 fois la vitesse du son), soit plus de 1 800 kilomètres par heure. La NASA espère que son appareil pourra, à terme, être utilisé dans le domaine de l’aviation civile.   Si les essais sont concluants, le X-59 QueSST pourrait donc avoir deux effets révolutionnaires sur le paysage aéronautique américain, voire mondial : L’avion d’essai pourrait servir d’inspiration à de futurs avions de transport produits en série, qu’il s’agisse d’avions de ligne ou d’avions d’affaire. L’ensemble du projet LBFD pourrait permettre une évolution de la réglementation aérienne actuelle. Plutôt que d’interdire tous les vols supersoniques civils au-dessus des USA, comme c’est le cas aujourd’hui, la NASA propose d’instaurer une réglementation en fonction du niveau de bruit.   Source : Lockheed Martin, NASA
