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

Exxelia Ohmcraft’s Small, Low-Noise Resistors Maximize Design Options and Accuracy for Sensor Manufacturers

For more than 25 years, leading sensor manufacturers have turned to Exxelia Ohmcraft to provide small-form-factor, ultra-low-noise surface mount resistors to be used in a variety of critical sensor applications. In these applications, Exxelia Ohmcraft’s resistors enable designers to miniaturize the sensor’s footprint or accommodate multiple sensors in close proximity to each other—all while increasing accuracy of the end products. Resistors have a certain amount of electrical noise that is inherent in their construction, and the higher the noise, the more distorted the signal can become. Exxelia Ohmcraft’s high-resistance, low-noise chip resistors provide clearer signals to the sensor electronics, thereby improving their accuracy. To ensure requirements are met for specialty sensors such as those used to measure acceleration, velocity, or vibration, Exxelia Ohmcraft works closely with design engineers, who appreciate the combination of high performance, reliability, and small form factor that the company can provide. “Finding resistors that check all of these boxes can be a challenge for sensor designers. At Exxelia Ohmcraft, our understanding of these requirements allows us to provide the highest performing solution at the lowest possible cost,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. "In sensor electronics, it can be difficult to distinguish the signal one is trying to measure from the noise of the surrounding environment, but our low-noise resistors ensure that the signal quality is maximized.” Exxelia Ohmcraft’s technology utilizes the proprietary Micropen electronic printing system to “print” precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.

Exxelia unveils new Innovative Aluminum Electrolytic Capacitor product line

FELSIC HC highest energy density of screw terminal aluminum electrolytic capacitor What if engineers could save 30% on room and weight, for a given energy storage function? This is now achievable with EXXELIA new FELSIC HC series of aluminum electrolytic screw terminal capacitors ! As Jérôme Tabourel, Exxelia Vice President of Marketing and Sales says: “Thanks to the use of improved materials, this new FELSIC family offers the highest energy density of the market, while still offering ultra-long life time”. These excellent characteristics allow to reduce the number of components used for the function, hence allowing room and weight savings of 30% on circuit board and greater reliability. Where to use FELSIC HC? These products are the perfect choice for Energy Storage and Power Industry equipment. SPECIFICATIONS: Capacitance from 100μF to 3 121 000μF  Energy density up to 21 µF/cm3 for a custom design Voltages from 10V to 500V Life time of 8000 hours at 85°C Operating Temperature -40°C to +85°C
