EXXELIA at Space Tech Expo EU 2019

Exxelia showcases Space Grade Magnetics & Ceramic Capacitors at Space Tech Expo Europe 2019 in Bremen, Germany

Exxelia showcases Space Grade Magnetics & Ceramic Capacitors at Space Tech Expo Europe 2019 in Bremen, Germany

November 5th, 2019 – Paris, France - Exxelia, a leading global designer and manufacturer of highly engineered passive components, will be showcasing its ESA qualified CCM technology and its EPPL C48X Ceramic Capacitors range booth K-24 at Space Tech Expo Europe, November 19-21 in Bremen, Germany.

 

ESA Qualified CCM Technology

Exxelia’s highly customizable Chameleon Concept Magnetics technology allows to manufacture inductors and transformers. Available in 5 different sizes allowing a high number of windings and up to 10*2 pins, this technology withstands harsh environments, shocks and vibrations and operates over a wide temperature range of -55°C / +125°C.   

Thanks to its epoxy molding protecting the windings and ensuring a better thermal dissipation to the pins and PCB, CCM products imply 50% less temperature rise, hence offering an additional 10 to 20% more power compared to a standard technology.

The CCM Technology in 5 key takeaways:

  • Ideal for the design of multi outputs transformers
  • Time saving & Higher reliability: up to 10*2 pins avoiding lead wire connections
  • Easy mounting on PCB: compatible with pick-and-place surface mount
  • Up to +20% more power versus standard technologies
  • No additional cost for tooling and qualification

 

C48X Ceramic Capacitor range officially listed in EPPL

Combining the advantages of class 1 (NPO) and class 2 (X7R) dielectrics, the C48X dielectric (-2,200ppm/°C) provides, under working voltage, equivalent capacitance values to an X7R material with the advantage of a very low dissipation factor of less than 5.10-4.

  • Withstands very high dV/dt, up to 10kV/ µs
  • Very low dissipation factor -> less than 5.10-4
  • Capacitance value of 3.3µF 200V -> up to 40 times more than an NPO
  • Polymer flexible layer for chips range

Compatible to surface mounting (chips, DIL or ribbon leads) or through-hole mounting and available from 200V to 5kV with sizes ranging from 1812 to 6560 allowing a maximum capacitance of 3.3µF at 200V, the EPPL C48X series is ideal for pulse and charge/discharge applications and precision filtering capacitance in thermally challenged environment for AC or DC voltage and 400 Hz application such as on-board network.

Exxelia onboard Solar Orbiter

Solar Orbiter, a European Space Agency mission, was launched on an Atlas V rocket 411 (AV-087) from Space Launch Complex 41 at Cape Canaveral Air Force Station at 11:03 p.m. EST on Sunday, Feb. 9 2020. The satellite reached its first working orbit around the Sun, called “halo orbit” and is ready to begin its first scientific observation campaign. The campaign will last six months, during which time the 55 payloads will be turned on one by one and tested before being used to perform scientific observations. Solar Orbiter is a highly complex scientific laboratory. Deploying such a mission is a one-of-a-kind achievement! The mission will take years and is one of the most highly anticipated scientific experiments of our time. And you know what they say: your best work comes when you're up against the toughest challenges. Unfortunately, these challenges aren't only in labs, but also in space. To study the Sun and its activity like never before, scientists are sending a probe into orbit around it. Solar Orbiter will be facing temperatures of up to 500°C, which is usually not survivable for complex equipment. But do you know what's even more challenging than getting data from a 500°C hot solar environment? Getting that data with expensive equipment that doesn't work, because you don't have enough reliable components at your disposal! That's why we, at Exxelia, were so happy when we heard that thousands of our capacitors and magnetics were chosen by the European Space Agency to achieve this mission; we're talking about components that will keep working in those kinds of harsh environments! They will help scientists better understand energy flow and particle acceleration within our own solar system and beyond. Shockingly, the Sun is mostly a mystery. We have some understanding of its composition, but it's unclear how the phenomena we see happen. Solar Orbiter is going to help us get a better idea of what makes the Sun tick by taking some of the most detailed images and observations of our star ever taken. Among the instruments on Solar Orbiter are: a Wide-Angle Imager and a Coronal Imager. Each will provide high-resolution images—an order of magnitude higher than those captured by NASA's Solar Dynamics Observatory—and spectacular views of the Sun's polar regions. The Wide-Angle Imager will capture images in five wavelengths, while the Coronal Imager will use seven wavelengths to observe phenomena that affect the upper layers of the solar atmosphere, such as magnetic fields and plasma flows. Our capacitors and magnetics are critical for stabilizing and powering these instruments on their mission to explore our home star! They need to be able to perform in a very hostile environment with temperatures ranging from -150°C (-238°F) to 500°C (932°F). Temperatures will reach their highest during the closest flybys of the Sun—which will take place as close as 15 million kilometers (about 93 million miles) from its surface. Our space capacitors and magnetics are capable of withstanding such high temperatures. They'll even keep functioning in cryogenic conditions, as low as -150°C (-238°F). These components are also very durable, which makes them perfectly suited for this mission.     Choosing the right capacitors for such a mission was not easy. The requirements and technical constraints were very strict. We had also to support and select the materials that could handle the launch vibrations and the shock of the rocket launching phase, we also had to achieve a very long life and high reliability in order to succeed in the mission. This project proves that our EXXELIA components are incredibly reliable and have nothing to envy to other electronic components on the market. Several other tests have been conducted by ESA in this project such as solar radiation, thermal shock...

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.
