Exxelia at Eurosatory

Exxelia is exhibiting at Eurosatory from June 11th to 15th in Paris, France. The company will be showcasing high-reliability electromechanical solutions and military grade passive components on hall 5A booth #E543.


State-of-the art absolute optical encoders
Exxelia has acquired deep expertise in the development of contactless position sensors of several type: absolute and incremental optical encoders, magnetic technology and inductive sensors. Several ranges of state-of-the-art absolute optical encoders will be showcased at the company booth - Hall 5A booth# E543. Absolute optical encoders are position sensors that use optical signals to identify an absolute angular position. They provide the highest resolution, operating speed reliability as well as long life operation in most demanding environments. Exxelia ranges of absolute optical encoders offer very high performance levels for a very small footprint: high precision (<30arcsc.), high resolution (up to 21 bits), extreme thinness (10mm) and EMI EMC compatibility. With their compact design, Exxelia miniature encoders meet the requirements of the most demanding application such as aerospace, defense, medical, oil & mining industries. Various protocols are available to match with any application. 
Exxelia encoders can be easily combined with other functions such as slip rings to provide customers turkey solutions.  

Two new ranges of MIL-qualified wet tantalum capacitors: MIL39006/22 & MIL39006/25
The recently introduced ranges of MIL-qualified tantalum capacitors will be showcased on the company booth. MIL 39006/22 and MIL 39006/25 respectively equivalent to CLR79 and CLR81 types featuring hermetically sealed cylindrical tantalum cases and axial leads are available in T1, T2 T3 and T4 cases with extended capacitance and voltage ratings. MIL 39006/22 is qualified for voltages from 6V to 125V and provides from 1200µF @6V to 56µF @125V. MIL 39006/25 is qualified for voltages from 25V to 125V and delivers from 680µF @25V to 82µF @125V. Both ranges combine high energy density with a large operating temperature range of -55°C - +125°C and H vibrations and shocks resistance.

Gammes de condensateurs HiQ à l'EuMW

  Exxelia Temex will be exhibiting at European Microwave Week 2016 through its mother group Exxelia. Showcased on the booth #237 will be all the company’s solutions intended for applications requiring low loss in equivalent series resistance (ESR) and high Q factor for specified DC or RF voltage, including Classic HiQ, Super HiQ and NHB series. Classic HiQ series is a range of RF ceramic capacitors providing low ESR and Ultra High-Q. The high-density ceramic construction provides a hermetic package and the highest working voltage on the market; up to 1500V and RF currents. Available in 0505 and 1111 sizes with capacitance values from 0.1pF up to 1000pF, the Classic HiQ series is perfectly adapted for applications such as: linear RF power amplifiers (LPA), mixers, filter networks, timing circuits, delay lines, oscillators, etc. Super HiQ series offers excellent performance in critical high RF power applications requiring consistent and reliable operation. The range has been engineered in all standard EIA sizes to provide constant capacitance over voltage, temperature and aging. It is also available in RF specific sizes (0402, 0603, 0805, 1206, 1210). The ultra-stable Super HiQ series offers Ultra-low ESR and Ultra HiQ with capacitance values from 0.2pF up to 1000pF. In addition, it enables superior high-voltage handling with working voltage up to 1500V. This series is particularly fit for cellular base station equipment, broadband wireless service, RF generators applications. Typical circuit applications: filters networks, matching networks, tuning, coupling and DC blocking. 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, available in 1111size 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 (Equivalent Series Resistance) is obtained by combining highly conductive metal electrodes and proprietary new NPO low loss rugged dielectrics. NHB series is particularly fit 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. All capacitors are packaged either as bulk chips or with tape or reel. All components are RoHS compliant and available with magnetic and non-magnetic terminations. They also provide as a good alternative for MIL-PRF-55681 / CDR capacitors. European Military, space grades and custom made capacitors are also available on request.

Nouveau diélectrique céramique haute tension, haute stabilité

La miniaturisation des systèmes électroniques est devenue un enjeu majeur et touche tous les domaines d’application. Afin de répondre à cette tendance, Exxelia Technologies (ex-Eurofarad) a développé une gamme de condensateurs céramique haute tension basée sur un tout nouveau matériau diélectrique (C48X) combinant tous les avantages des produits X7R et NPO/C0G. En effet, le C48X permet d’obtenir les mêmes valeurs de capacité sous tension que le X7R, avec l’avantage indéniable d’avoir un facteur de dissipation extrêmement faible (moins de 5.10-4). De plus, le C48X supporte un dV/dT très élevé jusqu’à 10kV/μs, faisant de ce matériau une solution de choix pour les applications nécessitant une charge/décharge ultra rapide ou pour des systèmes d’allumage. Les condensateurs C48X sont également parfaitement adaptés aux applications de puissance où la dissipation de chaleur peut être préjudiciable aux performances et à la fiabilité. Les condensateurs C48X du groupe Exxelia ont été développés des tailles 1812 à 16080 pour des tensions allant de 200 à 5000V, avec une capacité maximale de 10μF à 200V (10 fois supérieure par rapport à la capacité obtenue avec une céramique NPO). Les produits stackés sont proposés avec une capacité maximale de 47μF à 200V. Plusieurs solutions de report existent sur cette nouvelle gamme, compatible aussi bien avec un montage en surface qu’avec un report sur circuit à trous traversants. Toutes ces versions sont adaptées aux usages spatiaux et peuvent être conçues pour éviter le risque de whiskers (alliage étain-plomb à 10% de plomb mini). La gamme C48X est en cours d’introduction en EPPL ESA pour les tailles 0603 à 6560 de 100V à 1kV jusqu’à la taille 1210 et jusqu’à 5kV pour les tailles supérieures. Quelques applications usuelles : • Alimentations à 400Hz, • Defense • Spatial • Filtrage AC ou DC en environnement thermique
