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 HiQSuper 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.

NewNHB 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.

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
