Composants magnétiques innovants à l’APEC 2017 – stand 623 –
Exxelia participera au 2017 Applied Power Electronics Conference (APEC) à Tampa – Floride – du 27 au 30 mars 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.
Exxelia adopts laser marking for its products
Laser marking is part of the GREEN approach that Exxelia has recently implemented for its products. Indeed, it allows the reduction of the presence of chemicals in Exxelia magnetic products, currently, identified by ink marking which requires the use of protective varnish in order to resist the chemical cleaning agents used by our customers. Moreover, it allows a GREEN production with the drastic reduction of consumables (generally chemical) linked to ink marking and thus the need for recycling, for less impact on the environment. Exxelia is part of an eco-responsible approach with many industrial advantages, namely Indelible marking => optimal traceability (even on the smallest products), permanent and of constant quality. Resistance to corrosion and heat. Resistance to chemical agents => no need to use protective varnish on our markings. No more use of consumables (compared to ink marking).
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.
