Nouveau diélectrique céramique haute tension, haute stabilité

Exxelia annonce une nouvelle gamme de condensateurs céramique haute tension basés sur le nouveau matériau diélectrique C48X.

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

Exxelia Micropen Expands Manufacturing in Honeoye Falls

To accommodate current and future demand for its technologies, Exxelia Micropen has completed construction to expand its Honeoye Falls facility by more than 20 percent. The 9,000-square-foot addition includes 5,000 square feet of new cleanroom space, enabling the company to double the capacity of its manufacturing operations.   Exxelia Micropen utilizes its proprietary technology to “print” ultra-precise lines of conductive inks on three-dimensional and flexible surfaces, including advanced medical devices. The technology is also used to make high-performance resistors for a wide range of demanding applications in aerospace, imaging, and electronics. Since 2017, the company has experienced double-digit growth every year as demand for its innovative engineering, design, and manufacturing services has escalated.   “As we continue to develop new partnerships to meet the unique needs of customers across the globe, we outgrew our space,” “The expansion allows us to boost our production volumes while we continue to provide the innovative technologies and exceptional service and delivery times that our customers have come to rely on.” said Ed Petrazzolo, CEO, Exxelia Micropen.   Exxelia Micropen partnered with Hamilton Stern Construction and Hanlon Architects for the expansion, which began in the spring. In addition to the manufacturing space, the project includes a new lobby, employee breakroom, and more office space. Parking also grew to a total of 140 spaces.   “The expansion of Exxelia Micropen’s facility is a prime example of the success of our Design-Build service, which provides clients with a cohesive, one-stop-shop experience to save time and reduce costs,” said Justin Hamilton, Principal, Hamilton Stern. “Our close partnership with Hanlon Architects, Marathon Engineering, and Exxelia Micropen enabled this project to be completed in roughly 13 months all while fully maintaining the facility’s production volumes. We are grateful for Exxelia Micropen’s trust in our firm to be part of their continued growth.”   “We are proud of what we have built in Honeoye Falls,” said Petrazzolo. “The talented employees we’re able to recruit from the Rochester area are critical to our success, and the expansion only reinforces our commitment to further develop our presence here. We look forward to a long, prosperous future as part of this community.”
