Exxelia à Railtex 2017
Exxelia exposera du 9 au 11 mai sur le salon RailTex 2017, à Birmingham, Royaume-Uni. Sur son stand n° H02, Exxelia présentera une large sélection de condensateurs électrolytiques aluminium servant aux systèmes de signalisation et matériels roulants ferroviaires.
Felsic HV, long lifetime and high voltage screw terminal aluminum electrolytic capacitor
The Felsic HV family of aluminum electrolytic screw terminal capacitors provides great performances in energy density and ultra-long lifetime. For instance, 6 800µF @450V fit into a volume of Ø77 x 220mm and can withstand 200,000h between 0 to 70° under 37Amps, which makes them the perfect choice for use in rolling stock traction systems or the CVS. The family also has one of the lowest ESR for aluminum capacitors with less than 10m0hms in most cases. Products are available for voltages from 160 to 450 Vdc, and offer capacitance values from 1500μF up to 47 000μF offering the best compromise between reliability and compacity.
Snapsic HV, high voltage snap aluminum electrolytic capacitor
Because it covers voltages from 16 to 500Vdc and temperatures up to +105°C, and because it is customizable, the Snapsic HV series is very versatile and can cover all needs of energy storage in medium voltage both in rolling stock equipment or signaling systems. Thanks to its high ripple current, it is often used in SMPS and HVAC rolling stocks units with a typical variation of 470µF @450V in Ø35 x 50mm, as well as in various signaling control units, where a smaller package can be used with for example 1 000µF @250V in Ø35 x 40mm.
Prorelsic, the long lifetime axial aluminum electrolytic capacitors for signaling equipment
Exxelia’s range of aluminum electrolytic solutions would not be complete without the axial leaded Prorelsic series. These capacitors show high ripple current and extra-long life-time with 20 000h @105°C. The most common sizes are Ø8.5 x 19mm, Ø10 x 19mm and Ø12 x 30mm, with typical values of 47µF @40V, 100µF @25V and 47µF @100V respectively. Prorelsic capacitors are perfectly suited for smoothing, coupling/decoupling and energy storage functions in railway signaling equipment.
Nouvelle gamme de selfs mode commun, TCM
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.
WT83 - Condensateur tantale à électrolyte gélifié
La gamme WT83 est une extension des familles ST79 (suivant les valeurs MIL CLR93) mais avec deux fois plus de capacitance. C'est la solution parfaite pour miniaturiser les conceptions existantes en jouant sur la taille et le poids. Par exemple, le WT83 offre 470µF à 100V en taille D, alors que le ST79 n'offre que 220μF dans les mêmes conditions.
