Exxelia joins Heico Corporation group

Exxelia is turning a page in its shareholder history and should join the American group HEICO Corporation via its subsidiary Electronic Technologies Group (ETG).

The transaction will be carried out with IK Partners, majority shareholder of Exxelia since 2015, and should take place before the end of the first quarter of 2023.


Laurans A. Mendelson, HEICO's Chairman and Chief Executive Officer, along with Victor H. Mendelson, HEICO's Co-President and CEO of its Electronic Technologies Group, commented, "We are ecstatic that such a fine company, with its remarkable team members, management and products, will be part of HEICO, and we look forward to welcoming all of Exxelia's great people to the HEICO family. While furthering HEICO's strategy of expanding our already impressive range of mission-critical and Hi-Rel components for the most demanding applications, Exxelia also provides HEICO with added broad geographic and product diversity, including in the important European market."


Paul Maisonnier, CEO of Exxelia, commented, "We are excited to embark on a new stage of development with HEICO. We really appreciate the values of the Mendelson Family, which match perfectly those of Exxelia. Our goal to develop Exxelia into a world leader in Hi-Rel passive components and sub-systems for harsh environments, serving the aeronautic, defense, space and medical markets will be accelerated under the HEICO umbrella. Together we will strengthen our innovation and operational capabilities and accelerate our internationalisation strategy. We thank IK for their support over the past years, which has enabled us to establish a solid platform to support our ambitions for global growth."


Dan Soudry, Managing Partner at IK Partners and Advisor to the IK VII Fund, and Diki Korniloff, Partner at IK Partners, added: "As shareholders of Exxelia since 2015, we are very pleased to have been able to support its very talented management team through the various stages of transformation, structuring and growth of the Company, doubling its employee base to more than 2,100 people and leading to a strong increase in investment in R&D and in its manufacturing footprint. Notably, we believe that HEICO is an excellent home for Exxelia given that they share common values and we are very pleased HEICO is acquiring Exxelia. We'd like to take this opportunity to wish the team and HEICO all the very best for the future."

MIL 39006-Qualified Wet Tantalum Capacitors

Exxelia has received the M-Level (1.0%/1000h) MIL-PRF-39006/22 and MIL-PRF-39006/25 qualifications approval for its new ranges of wet tantalum capacitors. MIL 39006/22 and MIL 39006/25 respectively equivalent to CLR79 and CLR81 types feature hermetically sealed cylindrical tantalum cases and axial leads. Both ranges are available in all cases:  T1, T2 T3 and T4 with extended capacitance and voltage ratings. MIL39006/22 is qualified for voltages from 6V to 125V and provides from 1200µF @ 6V to 56 µF @ 125V. MIL 39006/25 is qualified for voltages from 25V to 125V and provides from 680µF @ 25V to 82 µF @ 125V. Both ranges combine high energy density with large temperature ranges -55°C up to 125°C and are available with H vibration and shocks features. These state-of-art MIL-qualified wet tantalum capacitors are widely used in avionics applications where high performance and extreme reliability are required. Performance highlights compared to solid tantalum capacitors include more capacitance, higher ripple currents, lower ESR and lower dc-leakage current. “These new ranges introduction leverages our decades of experience in providing high-reliability capacitors for the Military market, and proves Exxelia’s ability to reach the most demanding specifications in terms of product development”, states Exxelia Sales & Marketing VP, Jérôme Tabourel, “We are proud to be part of the few MIL-qualified manufacturers of tantalum capacitors, our flexibility and advantageous lead times will bring new supply perspectives.”  MIL39006/22 and MIL39006/25 are available for order now.          

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 !
