New entity, Exxelia Magnetics

Exxelia announces the fusion of its two companies, Exxelia Microspire and Exxelia N’Ergy, to create a single company Exxelia Magnetics.

This is an internal merger of two innovative, professional and complementary companies both designer and manufacturer of high-end would magnetic components, which have a history of successfully working together for a year.

Exxelia Magnetics will have greater scale, breadth and capabilities to compete more effectively in the global marketplace.

Exxelia Microspire

Microspire was founded in 1978 and became part of Exxelia Group in 2008.

Exxelia Microspire has been designing, developing and manufacturing wound components for over 35 years: transformers and inductors, electro-magnets, rotors and stators.

Exxelia Microspire has several manufacturing sites, notably newly located low production cost facilities offering competitive solutions.

Exxelia Microspire’s know-how includes standard winding technologies: linear (in RM, ETD, EP, EFD, ER, EQ and other formats) and toroid. For harsh environment applications with shock, vibration, and high temperature issues, Microspire offers innovative specific technologies including SESI, TT and CCM.

Exxelia Microspire’s qualified technologies, clearly defined design rules and industrial organization provide the platform on which it is able to offer its customers optimal solutions.

Exxelia N'Ergy

Exxelia N’Ergy (ex N’Ergy) was acquired in 2015 by Exxelia Group.  Exxelia N’Ergy designs and manufactures passive specific electromagnetic components in small and medium range:

Transformers,
Chokes,
Sensors (tachometer, gyros, …),
Electromagnets.

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 !
