Exxelia Ohmcraft Resistors serve Neurodiagnostics of Newborn Patients

ROCHESTER, N.Y., January 4, 2021—Neurodiagnostic tools are used every day in neonatal critical care units to monitor, diagnose and treat impairments in newborns.

This type of equipment successfully detects disorders in the brain, nerves and muscles that have the potential to impact the child’s long-term health. To ensure the reliability of this testing, global leaders in the manufacturing of neurodiagnostic technologies leverage Exxelia Ohmcraft’s custom, high voltage surface mount resistors in their equipment.

Exxelia Ohmcraft has the ability to provide high voltage resistors in a small form factor, which is essential for the smaller multi-channel patient monitoring equipment utilized in hospitals today. Additionally, the low noise of Exxelia Ohmcraft’s resistors is critical to eliminating interference that could impact the biosignals being transmitted from the newborn patient to the monitoring equipment.

“By utilizing our resistors, leading neurodiagnostics manufacturers have been able to develop cutting-edge monitoring and testing solutions that improve outcomes and enhance the care of the youngest and most vulnerable patients,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “We are proud to partner with many of the world’s top medical device manufacturers in the design of many products that are crucial to the diagnosis, treatment and prevention of so many diseases and conditions.”

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.

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

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.

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.
