Des composants Exxelia à bord du Rover Perseverance

Après la sonde InSight qui s'est posée sur la planète rouge le 26 novembre 2018 avec à son bord nos condensateurs film, c'est à bord du robot Perseverance qu'Exxelia fait son retour sur Mars !

 

Au terme d’un voyage de sept mois, le robot Perseverance de la NASA s'est posé sur Mars, hier à 21h55 heure Française. L'objectif de sa mission consiste à rechercher des traces de vie primitive ancienne sur la Planète rouge. 

Le robot est équipé de plusieurs instruments de mesure et de prélèvement, dont SuperCam, MEDA et PIXL sur lesquels nos composants sont embarqués:

  • Transformateurs et inductances: SESI, CMC et MPCI
  • Condensateurs film PM94
  • Condensateurs tantale solide CTC21
  • Résistances Ohmcraft HVD, HVR and CN 

L'objectif principal de SuperCam est de caractériser les roches présentes sur le sol Martien. L'instrument peut effectuer des analyses à distance grâce à son laser et à ses spectomètres, sans attendre le retour des échantillons sur terre.

L'analyseur dynamique, connu sous le nom de MEDA (Mars Environmental Dynamics Analyzer), effectue des mesures météorologiques, notamment la vitesse et la direction du vent, la température et l'humidité. Il mesure également la quantité et la taille des particules de poussière dans l'atmopshère martienne. 

PIXL est un spectromètre à fluorescence X qui fournira une détection et une analyse à échelle fine des éléments chimiques dans les roches et le sol.

Film capacitor series keeps its cool even at 150°C

The Exxelia Dearborn 880P series of metalised Polyphenylene Sulfide (PPS) Film Capacitors is designed to keep cool when things get hot. With an operating temperature range of -55 to +150°C, they experience no derating for DC operations and none in AC operations up to +125°C. This enables them to function at full capacity in extreme heat applications. The ability to operate at such high temperatures can eliminate the need for a cooling system within the design, thus reducing overall design time, weight and space. PPS is a high-temperature, low-loss dielectric film used in the 880P series of wrap-and-fill capacitors. This allows them to feature superior electrical characteristics over an extremely wide temperature range and maintain excellent capacitance stability in one rugged, lightweight package. It performs consistently well in commercial applications such as in power supplies and in more demanding applications, such as in avionics, on a congested control or instrumentation panel. The series features a capacitance range of 0.0047 to 10.0µF and voltage ratings from 50 to 400VDC with precision tolerances as low as ±¼% through ±10% yielding greater accuracy of capacitance. It is also a customisable unit with voltage maximums of 700 – 800VDC at 125°C maximum (higher voltages are available at reduced capacitance). Made in the USA, the units are highly durable and capable of withstanding a five-pound pull force on lead axis. They are non-polar and demonstrate low loss factor, good voltage breakdown strength and high insulation resistance (low leak current) – and are completely stable over normal temperatures, voltages and frequency ranges. These characteristics allow the 880P series capacitors to deliver high performance in a variety of applications such as DC timing circuits, low- to high-frequency AC applications, and pulse or energy discharge uses. Additionally, the package has axial leads with moisture-resistant, flame-retardant epoxy end seals and an outer tape covering for maximum performance.
