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.

100% invar tuning screws with self-locking system  Invar-36 is a unique Iron-Nickel alloy (64 % Fe / 36 % Ni) sought-after for its very low coefficient of thermal expansion. With 1.1 ppm. K–1 between 0°C and 100°C, Invar-36 is about 17 times more stable than Brass which is the most traditional and common alloy Tuning Elements are made of. The working temperature range in Space is so wide that this property becomes essential for a reliable and stable cavity filter tuning. Self-locking system is a technology commonly used on Tuning Element made of Brass or other soft “easy-to-machine” alloys but is innovative and pretty advanced when applied to hard and tough Invar 36. The design consists of two threaded segments separated by two parallel slots. After cutting both parallel slots, the rotor is compressed in its length in order to create a plastic deformation. Thus, an offset is induced between the two threaded segments which generates a constant tensile stress in the rotor from the moment threaded segments are screwed. High power and high frequency ceramics with the new C48X dielectric 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.   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 CCM technology adapts to most every need, even the harshest environments, including VIGON® resistance. 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. 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. 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.
