SPACE & MILITARY GRADE PASSIVES AT CMSE - BOOTH # B13 -

Exxelia will be showcasing Military and Space-qualified passive components (ESA QPL, MIL, DSCC, etc.) at the 2018 Components for Military and Space Electronics conference (CMSE) - booth# 13 - at the Sheraton Four Point Hotel in Los Angeles on May 7-10, 2018.


CMSE is one of the most recognized conference dedicated to the use of component in military and space systems. As a key supplier of highly reliable passive components, Exxelia will be displaying in booth B13, a wide variety of military and space-qualified capacitors (ceramic, tantalum, film, electrolytic aluminum), wound magnetics solutions and EMI/RFI filters.

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 (B13). MIL 39006/22 and MIL 39006/25 respectively equivalent to CLR79 and CLR81 types feature 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 56 µF @ 125V. MIL 39006/25 is qualified for voltages from 25V to 125V and delivers from 680µF @ 25V to 82 µF @ 125V. Both ranges combine high energy density with a large operating temperature range of -55°C - +125°C and H vibrations and shocks resistance.

Alsic 20G, Aluminum Electrolytic capacitors with large operating temperatures
 Alsic 20G is a range of radial leaded aluminum electrolytic capacitors for typical use in military and aerospace high frequency switch-mode power supplies requiring advanced performance under all operating conditions. Alsic 20G operational rated life is 8,000 hours at rated voltage and 105°C, and provides from 330µF @ 500V to 80 000μF @16V. The range features ruggedized design with insulating aluminum case and tin coated leads. With capacitance stability at high temperature, low inductance and impedance, competitive ESR and high ripple current, these capacitors are perfectly adapted for mission-critical applications. 

C48X dielectric: NPO and X7R advantages combined
Under working voltage, C48X dielectric provides equivalent capacitance values to an X7R material with the advantage of a very low dissipation factor (less than 5.10-4). It can also withstand very high dV/dt, up to 10kV/µs which makes it perfect for pulse and charge/discharge applications for firing units. Exxelia’s C48X capacitors, available from 200V to 5kV with EIA sizes from 1812 to 16080, are ideally suited for power applications where heat dissipation may be detrimental to performances and reliability, such as 400Hz Aircraft, Ignition systems, and Space, or as Precision/filtering capacitance in thermally challenged environment for AC or DC voltage.

Exxelia's Smart Magnetic: Breakthrough technology for more compact and powerful converters

This advance makes it possible to design more compact, lighter converters. However, the advantages of this technology are not limited to these fundamental aspects. In this article, we will explore in detail the multiple functional, economic and environmental benefits offered by Exxelia's Smart Magnetic technology.   Functional advantages for increased reliability: The Smart Magnetics project makes it possible in particular to optimize the Dual Active Bridge topology which requires the combination of a transformer and a choke. The Dual Active Bridge converter is a technology that is becoming widespread because it allows bidirectional power transmission. This meets the challenges of electrical systems (recovery + supply of energy), Integrating the Dual Active Bridge (DAB) transformer and choke into a single component has significant functional advantages. Unlike assembling two separate components, using an integrated component eliminates interconnections. The repeatability and reproducibility of the processes guarantee perfect control of the electrical characteristics, and ensure optimum performance of the converter. In addition, this consolidation reduces the number of components required, which improves the reliability of the final product.   Rationalization of the value chain for optimized production costs: The Smart Magnetic project also contributes to improving the value chain through effective streamlining. By replacing two distinct components with a single component, the management of the components of the circuit is simplified. From the customer's point of view, there is only one product to supply, one product to integrate/assemble in the system. These simplifications result in high added value and increased competitiveness on the market.   Contribution to a more environmentally friendly industry: By adopting Smart Magnetic solutions, the benefits go beyond simply improving energy efficiency. This innovation also reduces the consumption of raw materials by using less material in the Smart Magnetic component compared to standard formats requiring two separate components. As a result, this technology contributes to the preservation of natural resources. In addition, Smart Magnetic responds to the challenges posed by the electrification of vehicles, whether in air, land or sea transport, by promoting the deployment of solutions that are less dependent on fossil fuels.   Various applications: The versatility of Smart Magnetic solutions makes it suitable for many applications. For example, it can be used as a bi-directional converter between batteries and circuits, for power applications or even in resonant converter topologies. It is also useful in applications requiring high current and in Multi-output flyback converters. This diverse range of applications testifies to the flexibility of the Smart Magnetic project.   A project ? Do not hesitate to contact us.
