New Plug&Play filters for datacenters and mission critical facilities

New unrivalled Plug & Play TEMPEST filters for data centers and mission critical facilities.

Electronic equipment can leak sensitive information over conducted or radiated electromagnetic emanations, and signals transmitted down unprotected lines can potentially be intercepted. That’s why filters are implemented into systems to prevent EMI disturbances, as TEMPEST filters stop the high frequency EM signals (or noise) emanating inside the secured environment.

Exxelia has a long history of manufacturing state-of-the-art electromagnetic interference (EMI) filtering technologies for space, avionic and defense markets. Thanks to this in-depth knowledge, Exxelia came to the conclusion that the installation of a product is as critical as its reliability, especially when shielding continuity and sensitive copper terminals are involved.

That’s where Exxelia’s new full range of TEMPEST pluggable filters will save time and spare headaches! The 9260W series is a multi-socket line extension with a built-in 16A Tempest filter (minimum 60dB, from 100KHz to 1GHz), CE qualified according to EM 60950-1 standard. 9260W series Plug&Play solution is available with UK, US and EU standard plugs and can be provided with any other standard plug upon request.
In addition, Exxelia completed its offer with the 9259W series of pluggable filters featuring various plug interfaces such as VGA/DVI, USB, Ethernet, Phone, Audio and much more.

9260W series and 9259W series are both fully compliant with EMC expectations and allow considerable time saving and cost-effectiveness. When a standard filter needs to be wired and shielded to each socket one-by-one before carefully re-closing the whole equipment, Exxelia new series can be installed using no special tools and with a smaller footprint. To all people handling sensitive information, a simple plugging operation is now enough to protect their data.

Available now, 9259W and 9260W series are fully customizable upon request.

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 !

50th anniversary of our Pessac manufacturing site

Our manufacturing site in Pessac is one of the 12 industrial sites of Exxelia. It has approximately 130 employees. “We produce essential but inexpensive parts, but we produce 50 million a year! And we have a year of visibility on our order books", "We produce parts in complex alloys here, but also our own recipes for insulating ceramics", assures Mickaël Pelé, Director of the Exxelia Pessac factory. This factory was founded in Pessac half a century ago: it is an integral part of the life of the City and the Region, which have actively participated in its development. Perfectly inserted into the local ecosystem, there are numerous interactions with neighboring institutions, laboratories, universities, schools and businesses. The Pessac factory was built in 1971 and inaugurated in September 1972. Its creation was initiated by Jean-Claude Asscher, President of the Tekelec-Airtronic group. Initially dedicated to distribution, the Tekelec-Airtronic group launched into manufacturing under license to then develop and industrialize its own products. Its development followed that of electronics, telecommunications and IT in France and around the world. The group will reach a significant size: in 1992, with 20 companies employing 3,000 people in different countries, its turnover will exceed one billion dollars. The Pessac plant remained associated with the group until the early 2000s.   Here is a retrospective of the event in video:
