Certification QPL pour les gammes PM907S et PM98S

Exxelia annonce l’obtention de la qualification ESA/QPL pour ses gammes de condensateurs film : PM907S et PM948S.

 

Les gammes PM907S et PM948S de condensateurs film viennent d’être officiellement qualifiées QPL par l’organisme européen ESCC (European Space Components Coordination). La certification QPL atteste que les performances du produit ont été validées par un organisme accrédité indépendant. Les produits qualifiés QPL offrent une qualité et fiabilité supérieures, qui répondent aux exigences des applications spatiales.

Les gammes PM907S et PM948S appartiennent à la famille des condensateurs film polyester métallisés (PET), haute précision. La gamme PM907S est adaptée aux tensions de 50V à 1250V, et offre une capacité allant de 82nF jusqu’à 180μF. La gamme PM948S couvre quant à elle les tensions situées entre 50V et 630V, et offre une capacité allant de 22nF jusqu’à 47μF.

Ces deux gammes supportent des conditions extrêmes, des températures oscillant entre -55°C et +125°C, tout en offrant une forte concentration d’énergie, de faibles ESR et ESL, ainsi qu’un courant RMS élevé.
Ces produits sont principalement utilisés dans des alimentations à découpage et pour la fonction de filtrage des BUS.

La liste des gammes de condensateurs film certifiées QPL et développées par Exxelia, comprend désormais les gammes :
– PM90S
– PM907S
– PM96S (T)
– PM94S
– PM948S
– MKT5
– KM111S
– KM94S
– HT78PS

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:

NHB series - NPO dielectric

The NHB series is a complete range of MLCC based on NPO dielectric material providing a very high Self Resonant Frequency and limiting the parasite Parallel Resonant Frequencies. The series is available in 1111 size with capacitance ranging from 0. 3pF to 100pF. NHB series offers excellent performance for RF power applications at high temperature up to 175°C and at 500 VDC. The lowest ESR is obtained by combining highly conductive metal electrodes and proprietary of new NPO low loss rugged dielectrics. NHB series particularly fits for high power and high frequency applications such as: cellular base station equipment, broadband wireless service, point to point / multipoint radios and broadcasting equipment. Typical circuit applications: impedance matching, bypass, feedback, tuning, coupling and DC blocking.
