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

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 power and high frequency ceramics with the new C48X dielectric Range of high voltage ceramic capacitors based on brand new dielectric material C48X, combining most advantages of NPO and X7R dielectrics. Compared to X7R material, C48X dielectric allows to get the same capacitance values under working voltage with the unrivaled advantage of a very low dissipation factor (less than 5.10–4). Besides, it can also withstand very high dV/dt, up to 10kV/μs, which makes it the solution of choice for pulse and fast charge/discharge applications or firing units. Thus capacitors with C48X dielectric appear to be ideally suited for power applications where heat dissipation may be detrimental to performances and reliability. 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 CCM technology adapts to most every need, even the harshest environments, including VIGON® resistance. 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. 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. 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.
