Powerful ALUMUNIM ELECTROLYTIC CAPACITOR RANGES AT RAILTEX – BOOTH #H02
Exxelia is pleased to exhibit at RailTex 2017 in Birmingham, United-Kingdom. From May 9th to 11th at booth #H02, Exxelia will be showcasing innovative ranges of Aluminum Electrolytic capacitors for use in both rolling stock and signaling systems.
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.
QPL CERTIFICATION for PM907S & PM948S SERIES OF FILM CAPACITORS
Series PM907S and PM948S of Film capacitors obtained the QPL certification from the European Space Components Coordination (ESCC). According to the ESCC Detail Specification No. 3006/025 and 3006/026 QPL certified products ensure superior performances, quality and reliability intended for use by the European Space Agency (ESA) and in Space in general. PM907S and PM948S are full series of Polyester Film Capacitors. PM907S products are suitable for voltages from 50V up to 1250V and offer capacitance values from 82nF up to 180μF. PM948S can be used with a voltages from 50V up to 630V with capacitance values from 22nF up to 47μF. Both series can support extreme conditions with temperatures from -55°C to +125°C, and offer high energy density, low ESR & ESL and high RMS current. Products are typically being used in SMPS (Switch Mode Power Suppliers) and BUS filtering. These two certified series complete the list of Exxelia Group’s QPL certified film capacitors, that now includes: – PM90S – PM907S – PM96S (T) – PM94S – PM948S – MKT5 – KM111S – KM94S
Innovative new products at Electronica - Booth# B5 312 -
Felsic HV, long lifetime and high voltage screw terminal The Felsic HV family of aluminum electrolytic screw terminal capacitors provides great performances in energy density and ultra-long lifetime. For example products can withstand 8 000 hours at 105°C under high values of current which makes them the perfect choice to overcome railway constraints. The family also has one of the lowest ESR for aluminum capacitors, 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. Thus the family is a good compromise between reliability and compacity, with for example 47 000μF @ 160V in a 90x200mm volume. Cost-effective common-mode chokes qualified for aerospace Designed and qualified for aerospace, 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. Ceramic capacitors based on the new C48X dielectric New range of high voltage ceramic capacitors based on brand new dielectric material C48X, combining most advantages of NPO and X7R dielectrics. Compared to X7R material, C48X dielectric allows to get the same capacitance values under working voltage with the unrivaled advantage of a very low dissipation factor (less than 5.10-4). Besides, it can also withstand very high dV/dt, up to 10kV/μs, which makes it the solution of choice for pulse and fast charge/discharge applications or firing units. Thus capacitors with C48X dielectric appear to be ideally suited for power applications where heat dissipation may be detrimental to performances and reliability. Ultra low ESR, high RF power and high self-resonant frequency The new 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.
