Exxelia is proud to be a member of La French Fab banner.

La French Fab is the standard of the French industry in movement. A true unifying sign, gathering the SMEs, ETIs and large groups of the French territory.

La French Fab embodies the companies and industrial sites located in France who recognize themselves in the will to develop the French industry, adhere to the concepts and values of the brand and want to wear its colors.

With 6 industrial manufacturing plants in France, Exxelia shares the values of the French Fab in its desire to develop and transform French industry.

Like the French Fab, Exxelia is convinced that the transformation of industry requires innovation to achieve industry 4.0.

In order to achieve this objective, Exxelia has launched the development of industry 4.0 by placing digital technology at the heart of its strategy, and is currently in the deployment phase of this industry of the future which will contribute to the renewal of the French industrial ecosystem.

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 !
