Exxelia à PCIM 2017

Exxelia exposera sur le salon PCIM 2017 à Nuremberg, Allemagne. Du 16 au 18 mai, sur le stand n° 6314, la société exposera ses dernières solutions dédiées à l’électronique de puissance.

Magnetic Components based on Adaptive CCM Technology

Exxelia designed CCM technology to respond to the growing interest of electronic engineers for inductors and transformers with multiple outputs, high power density and reduced footprint. Qualified for aeronautic and space applications, the CCM product line features terrific robustness. The monolithic design provides high mechanical performance, proven by the successfully testing in accordance with MIL-STD-202 (methods 213 and 204). The series offers five different sizes, allowing optimized component design in a pick-and-place surface mount (SMD) package. Through-hole (TH) packages are also available upon request. The CCM series is particularly flexible with a number of pins options available, from 2×6 pins for the smallest package, up to 2×10. CCM transformers and inductors can operate over a wide temperature range with a minimal temperature of -55° C. The standard thermal grade of the technology is 140° C. Thanks to the technology design, the thermal resistance is 30% lower than standard industrial components. The epoxy molding protecting the winding ensures a lower temperature gradient and a better heat dissipation. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Component materials meet UL 94-V0 rating.

Cost-effective Common-mode Chokes Qualified for Aerospace

Exxelia designed this extensive and cost-effective range to be an easy commercial (COTS) solution for aerospace, defense, and other high-reliability applications. The TCM series is available in a through-hole package for horizontal or vertical mounting. TCM chokes are offered with inductances from 0.7 mH to 47 mH under rated currents from 0.3 to 4.0 A. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Excellent thermal properties allow the series to operate from -55° C to +125° C. The high mechanical performance of the component materials (all meeting to UL94 V0 rating) makes TCM a perfect fit for aviation, defense and transportation industries.

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.

MIL 39006-Qualified Wet Tantalum Capacitors

Exxelia has received the M-Level (1.0%/1000h) MIL-PRF-39006/22 and MIL-PRF-39006/25 qualifications approval for its new ranges of wet tantalum capacitors. MIL 39006/22 and MIL 39006/25 respectively equivalent to CLR79 and CLR81 types feature hermetically sealed cylindrical tantalum cases and axial leads. Both ranges are available in all cases:  T1, T2 T3 and T4 with extended capacitance and voltage ratings. MIL39006/22 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 provides from 680µF @ 25V to 82 µF @ 125V. Both ranges combine high energy density with large temperature ranges -55°C up to 125°C and are available with H vibration and shocks features. These state-of-art MIL-qualified wet tantalum capacitors are widely used in avionics applications where high performance and extreme reliability are required. Performance highlights compared to solid tantalum capacitors include more capacitance, higher ripple currents, lower ESR and lower dc-leakage current. “These new ranges introduction leverages our decades of experience in providing high-reliability capacitors for the Military market, and proves Exxelia’s ability to reach the most demanding specifications in terms of product development”, states Exxelia Sales & Marketing VP, Jérôme Tabourel, “We are proud to be part of the few MIL-qualified manufacturers of tantalum capacitors, our flexibility and advantageous lead times will bring new supply perspectives.”  MIL39006/22 and MIL39006/25 are available for order now.
