Exxelia onboard Solar Orbiter
Exxelia proud to be onboard Solar Orbiter which carries more than 16,000 of our passives to provide unprecedented insight into how our parent star works !
Solar Orbiter is the most complex scientific laboratory ever to have been sent to the Sun, our highly reliable space qualified capacitors and magnetics were chosen to complete the most delicate mission => resisting the most severe temperatures going up to 500°C for taking the closest ever images of the Sun, observing the solar wind and the Sun's polar regions like never before. Only our components were able to resist such a severe environment.
14,400 CEC/CNC chips ceramic capacitors
520 of our CNC stacks ceramic capacitors
470 SESI QPL Inductors
380 MSCI RF Inductors
287 ESA qualified CTC21/E Tantalum Capacitors & 50 ESA Film Capacitors PM94
NEW INVAR TUNING ELEMENTS WITH SELF-LOCKING SYSTEM
Working frequencies in Space applications are shifting to Ka, Ku or even Q band, while cavity filters are undergoing the general trend towards miniaturization: this context calls for a much more precise and stable tuning element now offered by Exxelia Temex, daughter company of Exxelia, through their last innovative and unrivalled solution to incorporate a self-locking system into their Invar Tuning Elements. Invar-36 is a unique Iron-Nickel alloy (64 % Fe / 36 % Ni) sought-after for its very low coefficient of thermal expansion. With 1.1 ppm. K–1 between 0°C and 100°C, Invar-36 is about 17 times more stable than Brass which is the most traditional and common alloy Tuning Elements are made of. The working temperature range in Space is so wide that this property becomes essential for a reliable and stable cavity filter tuning. Self-locking system is a technology commonly used on Tuning Element made of Brass or other soft “easy-to-machine” alloys but is innovative and pretty advanced when applied to hard and tough Invar 36. The design consists of two threaded segments separated by two parallel slots. After cutting both parallel slots, the rotor is compressed in its length in order to create a plastic deformation. Thus, an offset is induced between the two threaded segments which generates a constant tensile stress in the rotor from the moment threaded segments are screwed.
