Condensateurs céramique multicouches 0402 certifiés ESA QPL

Les gammes CEC et CNC de condensateurs céramique multicouches ont obtenu la certification QPL pour les tailles de boîtier 0402. Il s’agit de la taille de boîtier la plus petite ayant obtenu la certification QPL de l’ESA.

Les gammes de condensateurs céramique multicouches basse tension pour montage en surface, CEC19 et CNC19, ont obtenu le statut QPL respectivement selon les critères de l’ESCC 3009/042 et 3009/043. Les tailles de boîtier 0402 certifiées QPL sont disponibles de 10V à 25V, permettant un gain d’espace substantiel et un meilleur rendement. Les condensateurs céramiques d’Exxelia sont désormais certifiés QPL pour les tailles de boîtier de 0402 à 2220, de 10V à 100V.

Les condensateurs CEC sont réalisés avec le diélectrique NPO (type 1) reconnu pour sa très grande stabilité en tension et en température. Les CNC sont réalisés avec le diélectrique X7R (type2) qui offre la possibilité d’atteindre de fortes valeurs de capacité. Les versions avec des terminaisons polymères sont également certifiées QPL.

Ces condensateurs chips polyvalents sont développés pour être utilisés dans une multitude d’applications nécessitant une fiabilité à toute épreuve : satellites, lanceurs, charges utiles, etc.

CEC19 en bref :
- Diélectrique NPO qui présente une très grande stabilité
- Capacité maximale : 330pF à 10V, 120pF à 16V et 100pF à 25V,
- Grande plage de température : -55°C à 125°C

CNC19 en bref :
- Diélectrique X7R qui offre une grande capacité
- Valeurs de capacité élevées : de 68pF à 12nF à 10V, 8.2nF à 16V et 5.6nF à 25V
- Grande plage de température : -55°C to 125°C

Microwave Ferrites, Coaxial & Dielectric Resonators : Ask now !

Exxelia offers a wide range, including: Coaxial resonators : Resonators generally used in filters, duplexers, DRO's, and VCO's over a wide frequency range: 300 MHz to 6 GHz. They are available in several dimensions: 2x2, 4x4, 6x6, and up to 12x12 mm, offering the best compromise between impedance, Q factor, and resonance frequency.     Dielectric resonators : The dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia, with the support of the ESA and CNES, has developed the E7000 series which offers narrow bandwidth with reduced size. The E7000 dielectric resonator is based on Ba-Mg-Ta materials which combine ultra-high quality factor and the possibility to obtain all temperature coefficients on request. E7000 presents the high performances required for space use in the frequency range of 5 to 32 GHz and ensures up to Qxf > 250,000 at 10 GHz. As one of the few manufacturers producing its own raw materials, Exxelia perfectly masters the production of dielectric resonators. Encouraged by the success of this new range, Exxelia is now able to supply larger batches (up to 20 kg of powder) while retaining the same product properties.   Ferrites : Ferrites are magnetic materials used in a variety of applications. They are particularly effective in suppressing electromagnetic interference and noise in high-frequency applications, making them indispensable for modern communication systems. Ferrites are offered in disc, triangle, or specific designs. These materials are based on Exxelia formulations, offering low deltaH (ΔH) conducive to reducing IMD. Their combination with a dielectric material allows for a wide choice of composites (FDA) to miniaturize isolator/circulator designs. Exxelia's ferrites are distinguished by their exceptional quality and superior performance. These ferrites are made from high-quality materials and benefit from state-of-the-art design and manufacturing processes. They have been tested for use in demanding environments and have demonstrated exceptional reliability in applications up to 40 GHz.
