Exxelia dévoile une nouvelle gamme innovante de condensateurs électrolytiques aluminium

17 novembre 2020 - Paris, France - Exxelia, fabricant mondial de composants passifs complexes et de sous-systèmes dédiés aux environnements sévères, lance sa nouvelle gamme FELSIC HC, condensateurs Aluminium Electrolytique innovant.

FELSIC HC : la plus haute densité énergétique de condensateur électrolytique aluminium à bornes à vis

Et si les ingénieurs pouvaient économiser 30% de volume et de poids, pour une même capacité de stockage d'énergie ?

C'est désormais possible grâce à la nouvelle série de condensateurs aluminium électrolytiques à bornes à vis FELSIC HC d'EXXELIA !

Comme le dit Jérôme Tabourel, vice-président du Marketing et des Ventes d'Exxelia: "Grâce à l'utilisation de matériaux améliorés, cette nouvelle famille FELSIC offre la plus haute densité énergétique du marché, tout en ayant une durée de vie ultra longue".

Ces excellentes caractéristiques permettent de réduire le nombre de composants utilisés pour la fabrication, permettant ainsi un gain de volume et de poids de 30% et une plus grande fiabilité.

Où utiliser la gamme FELSIC HC ?  Ces produits sont le choix idéal pour le stockage d'énergie et les applications d’électronique de puissance.

 

CARACTÉRISTIQUES:

  • Capacité de 100μF à 3 121 000μF

  • Densité énergétique jusqu'à 21 µF/cm3 pour une conception personnalisée

  • Tension de 10V à 500V

  • Durée de vie de 8000 heures à 85°C

NEW INVAR TUNING ELEMENTS WITH SELF-LOCKING SYSTEM

Working frequencies in Space applications are shifting to Ka, Ku or even Q band, while cavity filters are undergoing the general trend towards miniaturization: this context calls for a much more precise and stable tuning element now offered by Exxelia Temex, daughter company of Exxelia, through their last innovative and unrivalled solution to incorporate a self-locking system into their Invar Tuning Elements. Invar-36 is a unique Iron-Nickel alloy (64 % Fe / 36 % Ni) sought-after for its very low coefficient of thermal expansion. With 1.1 ppm. K–1 between 0°C and 100°C, Invar-36 is about 17 times more stable than Brass which is the most traditional and common alloy Tuning Elements are made of. The working temperature range in Space is so wide that this property becomes essential for a reliable and stable cavity filter tuning. Self-locking system is a technology commonly used on Tuning Element made of Brass or other soft “easy-to-machine” alloys but is innovative and pretty advanced when applied to hard and tough Invar 36. The design consists of two threaded segments separated by two parallel slots. After cutting both parallel slots, the rotor is compressed in its length in order to create a plastic deformation. Thus, an offset is induced between the two threaded segments which generates a constant tensile stress in the rotor from the moment threaded segments are screwed.

Exxelia unveils two brand new High Temperature Film Capacitors series operating up to 200°C

Exxelia unveils two brand new High Temperature Film Capacitors series operating up to 200°C June 30th 2020 - Paris, France - Exxelia, an established designer and manufacturer of complex passive components, resistors & sub-systems dedicated to harsh environments, launches its new 253P & 560P product series providing unmatched performances at high temperature.   253P series, the 200°C Film capacitor series with unmatched stability The PTFE 253P series is the most stable 200°C Film capacitor on the market with its unparalleled stability of <2,5% with capacitance from 0.22μF to 1μF under 250VDC to 800VDC. It offers the lowest loss characteristic (Tẟ) of all film technologies less than 0,1% at extreme temperatures (200°C) with excellent life performance in operations. The series offers great resistance to vibrations, shocks and to over voltage making it ideal for Oil & Gas applications as well as Defense and Civil Aviation. SPECIFICATIONS: Voltages from 250VDC to 800VDC Capacitance from 0.22μF to 1μF Standard Tolerance ±10%, ±5%* Operating Temperature -55°C to +200°C  560P Film Capacitor series, is a High Temperature Polymer operating up to 180°C Exxelia’s 560P product series combines electrical performance between BOPP & PET while exhibiting a higher operating temperature up to 180°C and longer lifetime, it is the perfect cost-effective solution for high reliability and performance in severe environments. With absolutely no derating up to 150°C, its very stable TCC <2,5% and its great resistance to vibrations, shocks and over voltage, the series supplant high temperature ceramics and tantalums being an ideal choice for many capacitor applications in harsh environments i.e. DC Link, AC Filtering, ....   SPECIFICATIONS: Voltages from 320VDC to 800VDC Capacitance value from 0.022μF to 10μF Standard Tolerance ±10%, ±5%* Temperature ranges from -55°C to +180°C   Both series are available with a high degree of customization (* tighter tolerances available upon request). Representative samples are readily available for evaluation. For more information contact sales.usa@exxelia.com or visit www.exxelia.com
