Les résistances d'Exxelia Ohmcraft permettent de faire des analyses pointues en recherche pharmaceutique

Le 9 Avril 2020, Rochester, New York – Lors de l’élaboration de nouvelles thérapies pharmaceutiques, les chercheurs effectuent des analyses métaboliques des cultures de cellules vivantes pour comprendre le rôle essentiel du métabolisme dans une grande variété de maladies et de conditions.


Pour ce faire, ils doivent s’appuyer sur des instruments de recherche et de diagnostic en sciences de la vie dotés de circuits amplificateurs complexes à gain élevé. Les principaux fabricants de ce type d’équipement se sont associés à Exxelia Ohmcraft pour concevoir des résistances CMS spécifiques à forte valeur de résistance, essentielles au fonctionnement de ces circuits.

Plus précisément, le taux de consommation d’oxygène (OCR) et le taux d’acidification extracellulaire (ECAR) sont deux indicateurs clés de la respiration mitochondriale et de la glycolyse qui fournissent une vue d’ensemble de la fonction métabolique cellulaire dans les cellules en culture. L’équipement analyseur effectue ces mesures automatiquement.

« La précision et la fiabilité de ces outils sont cruciales pour permettre aux chercheurs de progresser dans leurs études, qui ont le potentiel de changer – voire sauver – des vies » déclare Eric Van Wormer, Vice-Président d’Exxelia Ohmcraft. “Pour répondre aux besoins de conception de cette application particulière, nous avons développé une résistance sur-mesure avec un facteur de forme unique et utilisé des terminaisons spéciales pour faciliter la fabrication du produit final.”

La technologie d’Exxelia Ohmcraft utilise le système d’impression électronique Micropen pour “imprimer” des lignes serpentines précises et étroites avec de l’encre résistive sur un substrat en céramique, produisant des résistances plus performantes sur une plage de valeurs plus large et sur une surface plus petite que la technologie « thick film » conventionnelle de résistances.

Revolutionary Exxelia MML™ Ultra-High Energy Density Film Capacitors

Discover the power of MML™ technology The best performing film capacitors on the market with the highest energy density ever! Exxelia&#39;s revolutionary MML™ ultra-high energy density Film Capacitors are a game changer in the industry due to their unparalleled energy density of 400 J/dm3. This allows for a significant reduction in size and weight in comparison to traditional Polypropylene or Polyester dielectrics, as well as an increased operating temperature of up to 140°C and protection against transient voltage. Not only do MML™ capacitors offer a large flexibility in design, allowing for low profile configurations, but they have also been tested in actual cases for controls and DC-Links functions in aircraft applications and have shown a reduction in size and weight of about 50% compared to other film technologies.   Furthermore, when compared to MLCCs, MML™ capacitors have demonstrated a reduction in weight of between 70% to 90%, with no capacitance derating with voltage applied and a low drift of less than 5% across the temperature range. Applications that previously required clusters of stacked MLCCs can now be replaced by a single MML™ unit of similar size, with the added reliability that film dielectric offers. The exceptional properties of Exxelia&#39;s new MML™ capacitors make them suitable for a wide range of applications including power supplies, DC-links, AC/DC/AC power converters, charge/discharge or power generation functions of commercial/military aircraft, satellite platforms and payloads, launchers, defibrillators, downhole tools and any other applications that require confined electronics. Samples are available upon request.   Features & Benefits : Miniaturization of the function : Up to 50% size reduction vs other film technologies ; matching footprint with stacked MLCC Lightweight : 50% lighter vs other film technologies ; 80 to 90% lighter than ceramic No capacitance derating in voltage, stable in temperature (<5% drift through the temperature range) Capacitance from 1μF to 1000μF  Voltages from 50V to 1000V  Operating Temperature -55 °C to +140 °C Highly customizable   Get your white paper around our MML Film Capacitor Download our white paper now on our innovative Miniature Micro-Layer™ (MML™) technology, which offers the highest capacitance per volume for film capacitors available on the market, by filling out the form below.   Chargement&hellip;

Exxelia joins Heico Corporation group

The transaction will be carried out with IK Partners, majority shareholder of Exxelia since 2015, and should take place before the end of the first quarter of 2023.   Laurans A. Mendelson, HEICO&#39;s Chairman and Chief Executive Officer, along with Victor H. Mendelson, HEICO&#39;s Co-President and CEO of its Electronic Technologies Group, commented, "We are ecstatic that such a fine company, with its remarkable team members, management and products, will be part of HEICO, and we look forward to welcoming all of Exxelia&#39;s great people to the HEICO family.
