  • Evolution of Electronics in the Civil Aeronautics Market

    04.22.2014 // Posted by: Didier Coulon

    The share of electronics in civil aircraft is rightly perceived as growing but is often overestimated in literature. The feeling that electronics are ubiquitous in the management of aeronautical systems may explain this mistake. Besides, if some electronic functions are relatively easy to identify like communications, radars, flight management systems or In-Flight Entertainment (IFE), others are less visible for example, those controlling certain traditional mechanical functions such as brakes, landing gear, flight controls, etc. Moreover, even if Electronic Control Units (ECUs) are clearly identifiable electronic sub-systems, other electronic equipment is disseminated in electronic systems (e.g. electronic equipment related to sensors and actuators). A trend reinforced with the arrival of a more electrical generation of aircraft like the Boeing 787 Dreamliner and the Airbus A350.

    For 2013, we estimate the production of electronic equipment dedicated to aeronautics to represent a 9.7 billion euro market at the world level. This market should grow at 8.1% per year until 2017. An excellent performance compared with the 3.2% of growth of the total world electronic production.

  • Green Chemistry: The Solution to the Environmental Regulation Problem for Electronics?

    05.01.2014 // Posted by: Mike Kirschner

    One of the greatest challenges electronics manufacturers continue to face in complying with the ever-expanding set of regulated chemical substances today is being aware of – in advance – whether any of the regulated substances are contained in their products. Despite a decade or more of demanding information on substances from their supply chains, the vast majority of manufacturers have little knowledge about substances beyond the RoHS six: lead, mercury, cadmium, hexavalent chromium, PBBs and PBDEs. And despite the Joint Industry Guide, JIG-101, having been around since 2005 (now supplanted by IEC 62474), most manufacturers can’t even seem to get information on that set of substances from much of their supply base. And with the list of disclosable REACH Substances of Very High Concern (SVHCs) at 151 heading toward as many as 500 by 2020, the industry appears to have a long way to go. Keep reading...

But the global weakness of the economy in the developed countries and a slower growth in the developing ones stopped this favourable orientation, and the world industrial electronic equipment production growth rate decreased from 8.4% in 2011 to 2.6% in 2012 and 3.5% in 2013.

Electromagnetic Components

Common Mode Choke

Common Mode Choke The common-mode inductor, or common mode choke (CM choke), is a passive electronic component used to remove EMI. Common-mode chokes are designed for high-speed applications, for switch-mode power supplies and DC power lines, circuits with poor or no grounding, and circuits with signal and noise that are "mixed", or pretty much on top of each other. This device is designed specifically for its unique frequency-selective properties, and the windings are designed for EMI suppression effectiveness. Two windings are precisely wound on a common magnetic core, and the result is a device that can scrub out noise that is "very close" to your desired frequency, and return a clear and balanced signal.


Inductors An Inductor is a length of conductor, normally wire, wound into a coil (thus the nickname that some people call this device) and around a core to concentrate the magnetic force (field) and maximize the inductance. The more turns of wire in the coil, the higher the inductance value. Inductors can be found in all facets of electronic design so they are not specific to one application area. Its primary properties are to resist changes in AC (alternating current) and to store and release energy from its magnetic field.

Multilayer Inductors

Multilayer Inductors Multilayer inductors can be made from one of two different cores, ceramic (air core) or ferrite. These inductors, when made in a ceramic core, usually possess high SRF’s and current ratings for higher frequency applications. When made in a ferrite core, the part will be naturally shielded and typically will have higher inductance values and higher Q factors at lower frequencies.

Thin Film Inductors

Thin Film Inductors Thin film inductors are the tightest tolerance inductors made. These are made specifically for High Q and high current characteristics within high frequency and lower inductance applications. Normally this would include RF and wireless applications including but not limited to the following applications: Bluetooth, Telecom Market, GPS, PDA, cellphones, etc. Typically they are used for impedance matching on your RF circuit. Another use for thin film inductors is for creating a resonant circuit (tuning a circuit).

Wirewound Inductors

Wirewound Inductors Wirewound inductors are the most versatile of the three technologies when it comes to their use in applications. This category of inductors includes not only chip inductors, but also all leaded inductors as well. A wirewound inductor will have the option to be magnetically shielded or not which helps it control unwanted signals from interfering with other components on the board especially important in filtering applications.
