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

HIGH VOLTAGE CERAMIC CAPACITORS BASED ON BRAND NEW DIELECTRIC MATERIAL

No more compromises between stability and capacitance! The brand new C48X material combines most advantages of NPO and X7R dielectrics, enabling the new high power and high frequency ceramic capacitor range to provide great stability in voltage, high capacitance, great dissipation factor and fast charge/discharge. Miniaturization is a driving need for future electronics pieces of equipment. This evolution, true whatever the application, leads Exxelia Technologies (ex-Eurofarad) to develop a brand new high voltage ceramic capacitors range based on a new dielectric material named C48X, combining most of the 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. Thus capacitors with C48X dielectric appear to be ideally suited for power applications where heat dissipation may be detrimental to performances and reliability. Exxelia Technologies’ capacitors based on the C48X material have been developed from 200V to 5kV with chip sizes ranging from 1812 to 16080, allowing a maximum capacitance value of 10μF 200V (10 times more than with an NPO ceramic). The standard stacked versions are proposed with a maximum capacitance value of 47μF 200V. Regarding the mounting of these capacitors, many configurations are possible to be compatible either with surface mounting or through-hole mounting. All these versions can be suitable for space use and can be designed in order to avoid any whisker growth risk (10% min lead in all tin-lead alloys used). The introduction of the C48X range in the EPPL (European Space Agency Preferred Parts List) for space is in progress for sizes 0603 to 6560 from 100V to 1kV up to size 1210 and up to 5kV until the size 6560). Some typical applications: • 400Hz Aircraft • Defense • Space • Precision/filtering capacitance in thermally challenged environment for AC or DC voltage
