Exxelia Ohmcraft Custom Resistors Enable Metabolic Analyses of Live Cell Cultures in Pharmaceutical Research

ROCHESTER, N.Y., April 9, 2020 — In the development of new pharmaceutical therapies, researchers conduct metabolic analyses of live cell cultures to understand the critical role of metabolism in a wide variety of diseases and conditions.

To do so, they must rely on life science research and diagnostic instruments with complex high gain amplifier circuits. Leading manufacturers of this type of equipment have partnered with Exxelia Ohmcraft to design custom, high-resistance surface mount resistors that are essential to the function of these circuits.

Specifically, oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) are two key indicators of mitochondrial respiration and glycolysis that provide a systems-level view of cellular metabolic function in cultured cells. The analyzer equipment conducts these measurements automatically.

“The accuracy and reliability of these tools are crucial to the researchers’ ability to make progress in their studies, which have the potential to change—and save—lives,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “To meet the design needs of this particular application, we developed a custom resistor solution with a unique form factor and used special terminations to facilitate the manufacturability of the end product.”

Exxelia Ohmcraft’s technology utilizes the proprietary Micropen electronic printing system to “print” precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.

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.

Retour sur notre présence au salon électronica 2022

  Pôle « Produits embarqués » ; rassemblant les composants pouvant être montés sur un satellite, un radar ou un avion, nous avons pu présenter deux innovations particulièrement adaptées aux défis de l’aviation du futur et des objectifs de décarbonation de l’aérien avec notre dernière innovation de condensateur film : MML™. Aux côtés des composants MML™, nous avons exposé les dernières innovations en matière de composants magnétiques, permettant de gagner jusqu’à 40% de poids et 20% de volume tout en dissipant plus de puissance, et dont certains ont été conçus pour des applications eVTOL, ainsi que les transformateurs multi-sorties CCM & Dual Active Bridge.   Pôle « Ferroviaire & Energie » ; nous avons exposé pour la première fois les condensateurs Alcon. Alcon est l’un des principaux concepteurs et fabricants indiens de condensateurs aluminium électrolytique et film, standards et sur-mesure, pour marchés de niche. Alcon fournit notamment de nombreux composants présents à bord des trains, des bornes de recharge électrique ou de systèmes de génération de puissance. Les condensateurs film et céramique d’Exxelia pour les systèmes de signalisation, ainsi que des transformateurs de courant et de mesure, et des résistances ont été aussi en démonstration.   Pôle médical ; les composants Exxelia Micropen & Exxelia Ohmcraft  ont été aussi présentés à Electronica pour la toute première fois avec une offre exceptionnelle pour le secteur médical. En effet, la technologie d’impression additive unique Exxelia Micropen est largement utilisée pour le matériel médical jetable tel que les tubes endotrachéaux ou les outils d’ablation chirurgicale, et les résistances haute tension  sont utilisées dans les équipements de laboratoire tels que les spectromètres de masse ou les thermocycleurs.
