Paris, France - August 29th 2019 – Exxelia, a leading global designer and manufacturer of highly engineered passive components and electromechanical solutions, celebrates the 10-year anniversary of its brand by confirming its market growth.
The group Exxelia was born from the merge of five long-established companies with complementary activities and know-how (Eurofarad, Firadec, Sic Safco, Microspire and Astema). Today, Exxelia counts thirteen manufacturing sites located in France, the United States, Vietnam and Morocco.
Embedded into the most advanced commercial aircrafts, the latest generation of fighter jets, onboard the most prestigious space exploration missions such as ChangE4 and Insight, Exxelia products have always been the trusted choice where the environment is harsh and reliability a must.
Paul Maisonnier, CEO of Exxelia says: “Over the past 10 years, Exxelia has double its revenue thanks to organic growth and strategic acquisitions. We are proud to be recognized as a leading designer and manufacturer of standard and custom solutions with a worldwide reputation for performance and quality.”
Looking ahead, Exxelia focuses on expanding its international presence to become the pure player world leader of complex passive components for high reliability applications.

What is a capacitor ?
▲ WHAT IS A CAPACITOR ? Definition from the dictionnary: « Capacitor »: Device able to accumulate charges and to relaunch them in a very short time. > See our capacitors in catalog What it really is: It's an electrical component made of 2 conductive armatures (called electrodes) separated by an isolating layer. Its main property is to store electrical charges on its armatures. There is a direct link between the voltage put on the capacitor and the value of the charge at the armatures This coefficient C, the capacitance, is the value caracterizing mathematically the capacitors. As we can identifie a direct link between U and I in the capacitor we can caracterize it as a dipole this way: 3 main dipoles : In the physical reality: Contacts with the PCB (terminations) + Other internal contact suh as the metallic contacts, or the physical internal resistivity of the used materials. → Resistance in the circuit Other losses due mainly to the leads → inductive effect in the circuit. Example of possible caracterization: That’s why the Esr is always written « at a certain frequency » which should be the resonnance frequency. This is also why the capacitors have frequency optimal ranges. The higher the resonance frequency is, the higher the frequencies are withstanded by the capacitor. In terms of energy Efficient energy is Ec. In reality E= Ec+Er+Ei with: Ec = Energy due to the ideal capacitor Er = Energy to the ESR Ei = Energy due to the leakage. So Er and Ei are caracterized by heating (Joule effect). So even if that’s not always a key paramter, the lower the esr the better it is for the circuit. If the capacitor is polarized : If the capacitor is not polarized : > See our capacitors in catalog ▲ MAIN CARACTERISTICS 1) Voltages (V) 2) Capacitance of Capacitor 3) Capacitance / volume 4) Tan Delta / ESR 5) Price of the function Whatever the function, the price of capacitors is important ! A cheap function does not mean a cheap product: 10 caps at 10€ is less expensive than 1 cap at 50€ … > See our capacitors in catalog ▲ FINAL OVERVIEW Technology Benefits of capacitors Constrains Aluminum The least expensive The highest energy density Polarized Difficulties in storage High ESR and tan Delta Lowest temperature range Ceramic Ideal for high frequencies The biggest range of values (CAPA voltage) Highest Price of the functions Low energy density Low values of capacitance Film Highest ripple curents Highest voltages Lowest ESR and tan Delta Most expensive Lowest energy density High price of the function Tantalum Lower ESR than aluminum, Good energy density and price of the function Polarized Solid can burn High ESR and tan Delta > See our capacitors in catalog
