Exxelia Showcased Space Grade Magnetics ＆ Ceramic Capacitors at Space Tech Expo Europe 2019
November 5th, 2019 - EXXELIA, a leading global designer and manufacturer of highly engineered passive components, showcased its ESA qualified CCM technology and its EPPL C48X Ceramic Capacitors range booth K-24 at Space Tech Expo Europe 2019, 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℃ / +125℃.
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.

WHAT ABOUT EXXELIA'S HIGH TEMPERATURE CERAMIC CAPACITORS?
High temperature ceramic capacitors and high temperature mica capacitors are often used in situations that require a higher voltage or a higher power than normal. Because of the ways in which they are built, they can offer low ESR and excellent inrush current and ripple capabilities that other types of capacitors cannot. The only downside is that they tend to be physically larger than other types of capacitors. The automotive industry is another area where high temperature capacitors are required. The temperature conditions can vary dramatically depending on what area of a car you’re talking about. The brake systems, the engine and the transmission are often the most temperature intensive areas.

From portable X-ray machines to satellite constellations, Exxelia supplies cutting-edge high reliability transformers and electronics magnetics solutions to ensure optimal performance in the most demanding environments.
MULTILAYER CERAMIC CAPACITORS MLCC
Our multilayer ceramic capacitor (MLCC) is a chip capacitor manufactured with layers of ceramic material and metal. The alternating layers can be built up to the desired capacitance range. The dielectric thickness determines the voltage rating. The capacitance is determined by multiplying the number of layers by the amount of active area and then the dielectric constant for the material. This number is then divided by the dielectric thickness. The active area is the overlap between the electrodes. A capacitor with a thicker dielectric layer handles higher voltages than one with a thinner layer. Inversely, the thinner dielectric will have a higher capacitance rating. The MLCC design provides a significant space-saving advantage over other capacitor styles.

DO I NEED CLASS 1 OR CLASS 2 CERAMIC CAPACITOR?
A Class 1 ceramic capacitor is the best choice for applications that demand low losses and high stability. This style provides a reliable capacitance within the designated range of frequency, temperature and voltage. Class 2 series offer higher capacitance, but have wider fluctuations. The thermal stability varies by +/- 15 percent; these should be used in applications that do not require a continual exact capacitance. Exxelia uses NPO and P100 as Class 1 dielectrics ; and BX, 2C1 and X7R as Class 2 dielectrics. Class 1 feedthrough capacitors offer high frequency noise reduction, and are excellent for use in microwave transmission, medical applications and DC supply and signal lines. Feedthrough design uses an axial-style lead for connections.
