Innovative new products at Electronica - Booth# B5 312 -

Exxelia will be exhibiting at Electronica, the biggest global trade fair for electronic components, which will take place from November 8th to 11th in Munich, Germany. On its booth # B5 312, the company will be showcasing a bunch of innovative new ranges.


Felsic HV, long lifetime and high voltage screw terminal
The Felsic HV family of aluminum electrolytic screw terminal capacitors provides great performances in energy density and ultra-long lifetime. For example products can withstand 8 000 hours at 105°C under high values of current which makes them the perfect choice to overcome railway constraints. The family also has one of the lowest ESR for aluminum capacitors, less than 10m0hms in most cases. Products are available for voltages from 160 to 450 Vdc, and offer capacitance values from 1500μF up to 47 000μF. Thus the family is a good compromise between reliability and compacity, with for example 47 000μF @ 160V in a 90x200mm volume.

Cost-effective common-mode chokes qualified for aerospace
Designed and qualified for aerospace, the TCM series is available in a through-hole package for horizontal and vertical mounting. TCM common-mode chokes are offered with inductances from 0.7 to 47mH under rated currents from 0.3A to 4A, and thoroughly tested by a dielectric withstanding strength at 1500VAC. Their excellent thermal properties allow the TCMs to operate without a hitch from -55°C up to +125°C, which, combined to the high mechanical resistance of the chosen materials (all meeting to UL94 V0 rating) make those products the perfect fit for aviation, defense and transportation industries.

Ceramic capacitors based on the new C48X dielectric
New 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.

Ultra low ESR, high RF power and high self-resonant frequency
The new 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.

Condensateurs céramique multicouches 0402 certifiés ESA QPL

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
