Powerful ALUMUNIM ELECTROLYTIC CAPACITOR RANGES AT RAILTEX – BOOTH #H02
Exxelia is pleased to exhibit at RailTex 2017 in Birmingham, United-Kingdom. From May 9th to 11th at booth #H02, Exxelia will be showcasing innovative ranges of Aluminum Electrolytic capacitors for use in both rolling stock and signaling systems.
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.
Larger Batches of High Q-Factor Dielectric Resonators
Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia with the support of ESA and CNES developed the E7000 series that provides a narrow bandwidth with smaller size. E7000 is Ba-Mg-Ta materials based that combines an ultra-high Q-factor and the possibility to get all the temperature coefficients upon request. E7000 features the high-performance requested for space use in the frequency range from 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ. Being one of the few manufacturers producing its own raw materials, Exxelia perfectly masters the production of dielectric resonators. Induced by the success of this new range, the company is now able to provide larger batches (up to 20kg of powder) of its E7000 series while keeping the exact same product properties, resulting in opportunities for cost-effective volume fabrication. Typical applications for the E7000 series: Satellite multiplexing filter devices, radio links for communication systems (LMDS), military radars.
Exxelia's components onboard Rover Perseverance
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.
