Exxelia's components onboard Rover Perseverance

After the InSight probe that landed on the Red Planet on November 26, 2018 with our film capacitors onboard, it is with the Perseverance robot that Exxelia proudly makes its return to Mars!


 

At the end of a seven-month journey, NASA's Perseverance robot has landed on Mars yesterday at 3:55 pm EST. The mission's objective is to search for traces of ancient primitive life on the Red Planet. The robot is equipped with several measuring and sampling instruments, including SuperCam, MEDA and PIXL served by our components: 

  • Transformers and Inductors : SESI, CMC and MPCI series
  • Film capacitors PM94 series
  • Tantalum capacitors CTC21 series
  • Ohmcraft resistors HVD, HVR and CN series

The main objective of SuperCam is to characterize the rocks present on Martian soil. The instrument can perform remote analyzes thanks to its laser and its spectometers, without waiting for the samples to return to earth, all with the aim of detecting any traces of primitive life.

The Mars Environmental Dynamics Analyzer, known as MEDA, makes weather measurements including wind speed and direction, temperature and humidity. It also measures the amount and size of dust particles in the Martian atmosphere.

PIXL is an X-ray fluorescence spectrometer that provides fine-scale detection and analysis of chemical elements within the rocks and soil.

Powerful ALUMUNIM ELECTROLYTIC CAPACITOR RANGES AT RAILTEX – BOOTH #H02

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 and ultra-long lifetime. For instance, 6 800µF @450V fit into a  volume of Ø77 x 220mm  and can withstand 200,000h 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 for aluminum capacitors with less than 10m0hms in most cases. Products are available for voltages from 160 to 450 Vdc, and offer capacitance values from 1500μF up to 47 000μF offering the best compromise between reliability and compacity. Snapsic HV, high voltage snap aluminum electrolytic capacitor Because it covers voltages from 16 to 500Vdc and temperatures up to +105°C, and because it is customizable, the Snapsic HV series is very versatile and can cover all needs of energy storage in medium voltage both in rolling stock equipment or signaling systems. Thanks to its high ripple current, it is often used in SMPS and HVAC rolling stocks units with a typical variation of 470µF @450V in Ø35 x 50mm, as well as in various signaling control units, where a smaller package can be used with for example 1 000µF @250V in Ø35 x 40mm.   Prorelsic, the long lifetime axial aluminum electrolytic capacitors for signaling equipment Exxelia’s range of aluminum electrolytic solutions would not be complete without the axial leaded Prorelsic series. These capacitors show high ripple current and extra-long life-time with 20 000h @105°C. The most common sizes are Ø8.5 x 19mm, Ø10 x 19mm and Ø12 x 30mm, with typical values of 47µF @40V, 100µF @25V and 47µF @100V respectively. Prorelsic capacitors are perfectly suited for smoothing, coupling/decoupling and energy storage functions in railway signaling equipment.
