High Q MLCC CP SeriesExxelia also features advanced High-Power High-Q series, designed for lower frequency applications with power handling up to 7200V and capacitance value up to 10nF. These capacitors are available in NPO and P90 dielectrics, offering exceptional performance with low ESR and ESL, making them ideal for the most demanding application. Those CP (P90) and CL (NP0) series are ideal for defense communication (VHF/UHF), medical MR body coils, and RF generators for plasma, semiconductor manufacturing, and extreme ultraviolet (EuV) lithography. 

 

Exxelia will also exhibit its comprehensive range of materials & tuning components, with a special focus on its cutting-edge microwave ferrite products. These advanced components are engineered to meet the rigorous demands of modern microwave applications, providing unparalleled performance and reliability. 

 

High Epsilon Ferrite YK21-DK21As a highlight of our presence at IMS Microwave Week, Exxelia will be pre-launching a new High-epsilon microwave ferrite. This new High-Epsilon Ferrite is featuring a permittivity of 21 and is available in two versions (YK21 and DK21) to address all power applications. It represents a significant advancement in ferrite technology, engineered to enhance the performance of high-frequency radar systems, especially in Active Electronically Scanned Array (AESA) radar applications. This new component delivers exceptional magnetic properties and stability, crucial for the optimal performance of isolator and circulator devices.

Exxelia's Smart Magnetic: Breakthrough technology for more compact and powerful converters

This advance makes it possible to design more compact, lighter converters. However, the advantages of this technology are not limited to these fundamental aspects. In this article, we will explore in detail the multiple functional, economic and environmental benefits offered by Exxelia's Smart Magnetic technology.   Functional advantages for increased reliability: The Smart Magnetics project makes it possible in particular to optimize the Dual Active Bridge topology which requires the combination of a transformer and a choke. The Dual Active Bridge converter is a technology that is becoming widespread because it allows bidirectional power transmission. This meets the challenges of electrical systems (recovery + supply of energy), Integrating the Dual Active Bridge (DAB) transformer and choke into a single component has significant functional advantages. Unlike assembling two separate components, using an integrated component eliminates interconnections. The repeatability and reproducibility of the processes guarantee perfect control of the electrical characteristics, and ensure optimum performance of the converter. In addition, this consolidation reduces the number of components required, which improves the reliability of the final product.   Rationalization of the value chain for optimized production costs: The Smart Magnetic project also contributes to improving the value chain through effective streamlining. By replacing two distinct components with a single component, the management of the components of the circuit is simplified. From the customer's point of view, there is only one product to supply, one product to integrate/assemble in the system. These simplifications result in high added value and increased competitiveness on the market.   Contribution to a more environmentally friendly industry: By adopting Smart Magnetic solutions, the benefits go beyond simply improving energy efficiency. This innovation also reduces the consumption of raw materials by using less material in the Smart Magnetic component compared to standard formats requiring two separate components. As a result, this technology contributes to the preservation of natural resources. In addition, Smart Magnetic responds to the challenges posed by the electrification of vehicles, whether in air, land or sea transport, by promoting the deployment of solutions that are less dependent on fossil fuels.   Various applications: The versatility of Smart Magnetic solutions makes it suitable for many applications. For example, it can be used as a bi-directional converter between batteries and circuits, for power applications or even in resonant converter topologies. It is also useful in applications requiring high current and in Multi-output flyback converters. This diverse range of applications testifies to the flexibility of the Smart Magnetic project.   A project ? Do not hesitate to contact us.

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.
