Nouvelle gamme de selfs mode commun, TCM

Exxelia introduit une nouvelle gamme  de selfs de mode commun, la gamme TCM. Fabriquée et qualifiée pour répondre aux exigences des applications aérospatiales, la gamme TCM est une solution compétitive dédiée aux les environnements sévères.

This extensive and cost-effective range is designed to be compatible with avionics applications.

The TCM series is available in a through-hole package for horizontal and vertical mounting. TCM common-mode chokes are offered with inductances from 0.7 to 47mH under rated currents from 0.3A to 4A, and thoroughly tested by a dielectric withstanding strength at 1500VAC. Their excellent thermal properties allow the TCMs to operate without a hitch from -55°C up to +125°C, which, combined to the high mechanical resistance of the chosen materials (all meeting to UL94 V0 rating) make those products the perfect fit for aviation, defense and transportation industries.

TCM series can be designed into circuit boards of a large number of power electronic devices used for a wide range of applications, including switch mode power supplies and converters, inverters, battery management systems, chargers.
Exxelia TCM series fully complies with the requirements of RoHS and REACH.

Exxelia revolutionary MML™ ultra-high energy density Film Capacitors

MML™ is a revolutionary new technology that provides the highest capacitance per volume in film capacitors available on the market.    Why is it a game changer? Because an unparalleled energy density of 400 J/dm3 allows for a tremendous reduction in size and weight compared to traditional Polypropylene or Polyester dielectrics, together with an increased operating temperature up to 140 °C and transient voltage protection.   Besides, MML™ capacitors offer a large flexibility in design, easily allowing low profile configurations. Several studies have been conducted on actual cases of controls and DC-Links functions for aircraft applications. All have shown about 50% reduction in size and weight compared to other film technologies.  The comparative picture with MLCC is even more flattering, as it demonstrates between 70% to 90% reduction in weight, while showing no capacitance derating with voltage applied and a low drift < 5% through the temperature range. Applications using clusters of stacked MLCCs can now be replaced by a single MML™ unit of similar size, with all the increased reliability that film dielectric offers. With such outstanding properties, Exxelia new MML™ capacitors are perfectly suitable for power supplies, DC-links, AC/DC/AC power converters, charge/discharge or power generation functions of commercial/military aircraft, satellite platforms and payloads, launchers, defibrillators, downhole tools and any applications of confined electronics. Samples are readily available on request. Features & Benefits : Miniaturization of the function : Up to 50% size reduction vs other film technologies ; matching footprint with stacked MLCC Lightweight : 50% lighter vs other film technologies ; 80 to 90% lighter than ceramic No capacitance derating in voltage, stable in temperature (<5% drift through the temperature range) Capacitance from 1μF to 1000μF  Voltages from 50V to 1000V  Operating Temperature -55 °C to +140 °C Highly customizable
