Larger Batches of High Q-Factor Dielectric Resonators

Exxelia can now produce larger batches of its E7000 series for increased cost-effectiveness. Designed for high-end filters where Q-factor is critical, especially in space or military applications, the E7000 series of dielectric resonator features tremendous properties.


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.

Introducing new EXXELIA.COM

Completely re-designed Exxelia new website features user-friendly design, improved functionalities and enhanced rich content to assist electronic engineers, component purchasers, industry professionals and students to quickly access information.  Created with the user experience firmly in mind, the website has been designed to make Exxelia’s vast product portfolio easy to browse. A parametric search engine with filters specific to each product category (capacitance, voltage, temperature, insertion loss, current, frequency, etc.) enables to narrow down the product portfolio and access information in a quick, trouble free and efficient way. More than 680 product series are listed on the website with relevant literature accessible for each series: datasheets, 3D models, high-res pictures and much more.      Technical data, application guides, white papers work together to provide a detailed overview of Exxelia’s capabilities across wide range of technologies. An application section presents the major markets the group is involved in, with a dedicated product selection for every sub-environments: avionics & cockpit, actuation systems, satellites, radars, medical imaging, etc. This section also contributes to better present Exxelia’s diversified offer of components that includes capacitors, magnetics, filters and electromechanical solutions.  “We are thrilled about the new website launch and the robust information it provides to better understand Exxelia wide product offering. We believe this will improve the overall customer experience and strengthen our brand as a technology leader and quality product manufacturer” said Marie Evrard, Head of Marketing and Communication at Exxelia.  “We believe this new site will allow our visitors to have a very informative experience as we increase our market presence. The group continues to grow and it was necessary to streamline our website to make it easier to navigate.” states Jérôme Tabourel, Marketing & Sales VP at Exxelia. Exxelia new website will be updated on a regular basis with new product launches, company info, events and technical information.  

Magnetic Components based on Adaptive CCM Technology at APEC – Booth# 653 –

Exxelia will exhibit the CCM series during the Applied Power Electronics Conference at Exxelia’s booth #623 from March 27-30, 2017 in Tampa, FL. 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. Exxelia can evaluate losses and related temperature rise thanks to an in-depth knowledge of CCM technology. Thermal resistance data is available for each package size. Exxelia can also manufacture products in CCM technology according to MIL-STD-981.
