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.

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.
