Gammes de condensateurs HiQ à l'EuMW
Exxelia exposera au salon European Microwave Week, du 4 au 6 octobre à l’Excel London, stand n°237. L’occasion de présenter les principales gammes de condensateurs RF/Microwave : Classic HiQ, Super HiQ ainsi que la nouvelle gamme NHB.
Exxelia Temex will be exhibiting at European Microwave Week 2016 through its mother group Exxelia. Showcased on the booth #237 will be all the company’s solutions intended for applications requiring low loss in equivalent series resistance (ESR) and high Q factor for specified DC or RF voltage, including Classic HiQ, Super HiQ and NHB series.
Classic HiQ series is a range of RF ceramic capacitors providing low ESR and Ultra High-Q. The high-density ceramic construction provides a hermetic package and the highest working voltage on the market; up to 1500V and RF currents. Available in 0505 and 1111 sizes with capacitance values from 0.1pF up to 1000pF, the Classic HiQ series is perfectly adapted for applications such as: linear RF power amplifiers (LPA), mixers, filter networks, timing circuits, delay lines, oscillators, etc.
Super HiQ series offers excellent performance in critical high RF power applications requiring consistent and reliable operation. The range has been engineered in all standard EIA sizes to provide constant capacitance over voltage, temperature and aging. It is also available in RF specific sizes (0402, 0603, 0805, 1206, 1210). The ultra-stable Super HiQ series offers Ultra-low ESR and Ultra HiQ with capacitance values from 0.2pF up to 1000pF. In addition, it enables superior high-voltage handling with working voltage up to 1500V. This series is particularly fit for cellular base station equipment, broadband wireless service, RF generators applications.
Typical circuit applications: filters networks, matching networks, tuning, coupling and DC blocking.
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, available in 1111size 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 (Equivalent Series Resistance) is obtained by combining highly conductive metal electrodes and proprietary new NPO low loss rugged dielectrics.
NHB series is particularly fit for high power and high frequency applications such as: cellular base station equipment, broadband wireless service, point to point / multipoint radios and broadcasting equipment.
Typical circuit applications: impedance matching, bypass, feedback, tuning, coupling and DC blocking.
All capacitors are packaged either as bulk chips or with tape or reel. All components are RoHS compliant and available with magnetic and non-magnetic terminations. They also provide as a good alternative for MIL-PRF-55681 / CDR capacitors. European Military, space grades and custom made capacitors are also available on request.

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.
