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.

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.

Magnetic Components based on Adaptive CCM Technology Exxelia designed CCM technology to respond to the growing interest of electronic engineers for inductors and transformers with multiple outputs, high power density and reduced footprint. Qualified for aeronautic and space applications, the CCM product line features terrific robustness. The monolithic design provides high mechanical performance, proven by the successfully testing in accordance with MIL-STD-202 (methods 213 and 204). The series offers five different sizes, allowing optimized component design in a pick-and-place surface mount (SMD) package. Through-hole (TH) packages are also available upon request. The CCM series is particularly flexible with a number of pins options available, from 2×6 pins for the smallest package, up to 2×10. CCM transformers and inductors can operate over a wide temperature range with a minimal temperature of -55° C. The standard thermal grade of the technology is 140° C. Thanks to the technology design, the thermal resistance is 30% lower than standard industrial components. The epoxy molding protecting the winding ensures a lower temperature gradient and a better heat dissipation. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Component materials meet UL 94-V0 rating. Cost-effective Common-mode Chokes Qualified for Aerospace Exxelia designed this extensive and cost-effective range to be an easy commercial (COTS) solution for aerospace, defense, and other high-reliability applications. The TCM series is available in a through-hole package for horizontal or vertical mounting. TCM chokes are offered with inductances from 0.7 mH to 47 mH under rated currents from 0.3 to 4.0 A. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Excellent thermal properties allow the series to operate from -55° C to +125° C. The high mechanical performance of the component materials (all meeting to UL94 V0 rating) makes TCM a perfect fit for aviation, defense and transportation industries.
