Exxelia at EMV

Exxelia is pleased to exhibit at EMV 2019 in Stuttgart, Germany from March 19 to 21 inHall C2 Booth# 113, Exxelia will be introducing a new filter design conception.

Showcased at Exxelia’s booth #113 in Hall C2, will be Asymmetric filter solutions, the most optimized design in the market.
Smaller, lighter and consequently easier to install, Exxelia is the only manufacturer to solve HEMP requirements with Asymmetric filter designs, hence addressing the security challenges of tomorrow.

Exxelia pushes the limits of design with the new BDP series allowing a 50% space saving in your installation while keeping high technical specifications (insertion loss of 80dB, 1250A, 300kHz to 18GHz) and complying with the MIL STD 188 125 1&2 test requirements.

Asymmetric designs allow to combine safety and miniaturization while still handling HEMP and TEMPEST requirements. Three important benefits stand out from this conception, starting with a lower heat dissipation: as no magnetic field is generated, inductors suffer no heat dissipation. Secondly, the leakage is significantly lower thanks to a low value capacitance. Finally by using only one common inductor, these designs definitely save space.

Dr. Guillaume Aubard, Exxelia Filters’ Business Development Manager will be speaking at EMV Forum Hall C2-319 on March 20th from 3:40pm to 4pm about the Asymmetric filter solutions for HEMP and TEMPEST following by a Q&A.

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

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.

Exxelia Ohmcraft’s Small, Low-Noise Resistors Maximize Design Options and Accuracy for Sensor Manufacturers

For more than 25 years, leading sensor manufacturers have turned to Exxelia Ohmcraft to provide small-form-factor, ultra-low-noise surface mount resistors to be used in a variety of critical sensor applications. In these applications, Exxelia Ohmcraft’s resistors enable designers to miniaturize the sensor’s footprint or accommodate multiple sensors in close proximity to each other—all while increasing accuracy of the end products. Resistors have a certain amount of electrical noise that is inherent in their construction, and the higher the noise, the more distorted the signal can become. Exxelia Ohmcraft’s high-resistance, low-noise chip resistors provide clearer signals to the sensor electronics, thereby improving their accuracy. To ensure requirements are met for specialty sensors such as those used to measure acceleration, velocity, or vibration, Exxelia Ohmcraft works closely with design engineers, who appreciate the combination of high performance, reliability, and small form factor that the company can provide. “Finding resistors that check all of these boxes can be a challenge for sensor designers. At Exxelia Ohmcraft, our understanding of these requirements allows us to provide the highest performing solution at the lowest possible cost,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. "In sensor electronics, it can be difficult to distinguish the signal one is trying to measure from the noise of the surrounding environment, but our low-noise resistors ensure that the signal quality is maximized.” 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.
