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.

HIGH VOLTAGE CERAMIC CAPACITORS BASED ON BRAND NEW DIELECTRIC MATERIAL

No more compromises between stability and capacitance! The brand new C48X material combines most advantages of NPO and X7R dielectrics, enabling the new high power and high frequency ceramic capacitor range to provide great stability in voltage, high capacitance, great dissipation factor and fast charge/discharge. Miniaturization is a driving need for future electronics pieces of equipment. This evolution, true whatever the application, leads Exxelia Technologies (ex-Eurofarad) to develop a brand new high voltage ceramic capacitors range based on a new dielectric material named C48X, combining most of the advantages of NPO and X7R dielectrics. Compared to X7R material, C48X dielectric allows to get the same capacitance values under working voltage with the unrivaled advantage of a very low dissipation factor (less than 5.10-4). Besides, it can also withstand very high dV/dt, up to 10kV/μs, which makes it the solution of choice for pulse and fast charge/discharge applications. Thus capacitors with C48X dielectric appear to be ideally suited for power applications where heat dissipation may be detrimental to performances and reliability. Exxelia Technologies’ capacitors based on the C48X material have been developed from 200V to 5kV with chip sizes ranging from 1812 to 16080, allowing a maximum capacitance value of 10μF 200V (10 times more than with an NPO ceramic). The standard stacked versions are proposed with a maximum capacitance value of 47μF 200V. Regarding the mounting of these capacitors, many configurations are possible to be compatible either with surface mounting or through-hole mounting. All these versions can be suitable for space use and can be designed in order to avoid any whisker growth risk (10% min lead in all tin-lead alloys used). The introduction of the C48X range in the EPPL (European Space Agency Preferred Parts List) for space is in progress for sizes 0603 to 6560 from 100V to 1kV up to size 1210 and up to 5kV until the size 6560). Some typical applications: • 400Hz Aircraft • Defense • Space • Precision/filtering capacitance in thermally challenged environment for AC or DC voltage

Exxelia equips the Turkish satellite IMECE with tantalum and ceramic capacitors

IMECE is a technological feat that pushes the boundaries of high-resolution imaging. Exxelia is proud to play an essential role in this space adventure by providing quality components to ensure proper operation.   IMECE is an earth observation satellite designed and developed by TÜBİTAK Space Technologies Research Institute (TÜBİTAK UZAY) and produced in Türkiye to provide high-resolution imagery. The spacecraft has a mass of 800 kg (1,800 lb) and it will serve at 680 km (420 mi) on a sun-synchronous geocentric orbit. The Satellite, projected for a mission duration of five years, has 0.99m image resolution of Panchromatic (PAN). The satellite has been launched on 15 April 2023 on a SpaceX's Falcon 9 Block 5 rocket as part of the Transporter-7 ridershare mission.   Exxelia equips the satellite with PM series capacitors that are used in the satellite's Power Distribution Unit (PDU). Exxelia's PM series capacitors are renowned for their reliability, performance, and durability, making them ideal for space applications. Exxelia also supplies tantalum capacitors and ceramic capacitors for the payloads of the IMECE Satellite. These components are designed to withstand the extreme conditions of space and ensure the proper operation of scientific instruments and equipment on board the satellite.   We look forward to the discoveries and data that the IMECE Satellite will provide during its five-year mission. The future of space exploration looks promising, and Exxelia will continue to play an active role in this exciting adventure.
