Exxelia at IMS

Exxelia is pleased to exhibit at IMS in Philadelphia, USA. From June 11 to 15 at booth# 2050, the company will be previewing several high-reliability microwave and RF components dedicated to a variety of industries including medical, transportation and defense.


Ultra low ESR, high RF power and high self-resonant frequency

The NHB series is a complete range of MLCC based on NPO dielectric material providing a very high Self Resonant Frequency and limiting the parasite Parallel Resonant Frequencies. The series is available in 1111 size with capacitance ranging from 0. 3pF to 100pF. NHB series offers excellent performance for RF power applications at high temperature up to 175°C and at 500 VDC. The lowest ESR is obtained by combining highly conductive metal electrodes and proprietary of new NPO low loss rugged dielectrics. NHB series particularly fits for high power and high frequency applications such as: cellular base station equipment, broadband wireless service, point to point / multipoint radios and broadcasting equipment. Typical circuit applications: impedance matching, bypass, feedback, tuning, coupling and DC blocking.

100% invar tuning screws with self-locking system  

Invar-36 is a unique Iron-Nickel alloy (64 % Fe / 36 % Ni) sought-after for its very low coefficient of thermal expansion. With 1.1 ppm. K–1 between 0°C and 100°C, Invar-36 is about 17 times more stable than Brass which is the most traditional and common alloy Tuning Elements are made of. The working temperature range in Space is so wide that this property becomes essential for a reliable and stable cavity filter tuning. Self-locking system is a technology commonly used on Tuning Element made of Brass or other soft “easy-to-machine” alloys but is innovative and pretty advanced when applied to hard and tough Invar 36. The design consists of two threaded segments separated by two parallel slots. After cutting both parallel slots, the rotor is compressed in its length in order to create a plastic deformation. Thus, an offset is induced between the two threaded segments which generates a constant tensile stress in the rotor from the moment threaded segments are screwed.

High Q Factor Dielectric Resonators in large batches

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.

Exxelia à PCIM 2017

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.

Condensateurs au tantale qualifiés MIL-PRF-39006

Exxelia introduit deux nouvelles gammes de condensateurs tantale gélifiés ayant obtenu la qualification MIL-PRF-39006 de niveau M (1.0% / 1000h) : MIL 39006/22 & MIL 39006/25. Ces deux gammes, respectivement équivalentes aux modèles CLR79 et CLR81, associent compacité, fort courant efficace et faible courant de fuite. Conçus avec un boîtier tantale cylindrique hermétique avec terminaisons axiales, les produits MIL 39006/22 & MIL 39006/25 sont proposés dans des tailles de boîtier standards de T1 à T4 avec des plages de capacitance et de tension étendues. La gamme MIL 39006/22 est qualifiée pour des tensions de 6V à 125V, avec des capacités allant de 1200µF @ 6V  à 56 µF @ 125V. La gamme MIL 39006/25 est quant à elle qualifiée pour des tensions de 25V à 125V avec des capacités allant de 680µF @ 25V à 82 µF @ 125V. Ces deux gammes combinent une grande capacité de stockage d’énergie avec une plage étendue de température de fonctionnement de -55°C à 125°C, ainsi qu’une très bonne tenue aux chocs et vibrations (option H disponible).            Les condensateurs tantale gélifiés qualifiés MIL sont principalement utilisés pour des applications aéronautiques où performances techniques avancées et extrême fiabilité sont nécessaires. « Exxelia possède un long historique dans la fabrication de condensateurs dédiés aux marchés exigeants comme la défense, le spatial ou encore l’aéronautique. Ces nouvelles gammes démontrent notre capacité à développer des produits répondant aux spécifications les plus exigeantes en matière de fiabilité", explique Jérôme Tabourel, Directeur Marketing & Ventes d’Exxelia. « Nous sommes fiers de compter parmi les quelques fabricants de condensateurs tantale ayant obtenu la qualification MIL, notre flexibilité et nos délais avantageux apporteront de nouvelles perspectives d’approvisionnement sur ce marché. » Les gammes MIL 39006/22 et MIL 39006/25 sont disponibles à la commande.
