High-end RF capacitors showcased at electronica

A range of RF/Microwave capacitor products were exhibited by Exxelia at electronica. The company showcased its 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 the NHB series.

The Classic HiQ series is a range of RF ceramic capacitors providing low ESR and high-Q. The high-density ceramic construction provides a hermetic package and a working voltage of up to 1,500 V and RF currents. Available in 0505 and 1111 sizes with capacitance values from 0.1-1,000pF, the Classic HiQ series is adapted for applications such as: Linear RF Power Amplifiers (LPA), mixers, filter networks, timing circuits, delay lines and oscillators.

The Super HiQ series offers strong 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 stable Super HiQ series offers low ESR and ultra HiQ with capacitance values from 0.2-1,000pF. In addition, it enables superior high-voltage handling with working voltage up to 1,500 V. This series is particularly fit for cellular base station equipment, broadband wireless service and RF generators applications. Typical circuit applications include filters networks, matching networks, tuning, coupling and DC blocking.

The NHB series is a range of MLCC based on NPO dielectric material providing a high self resonant frequency and limiting the parasite parallel resonant frequencies, available in 1111 size with capacitance ranging from 0.3-100pF. The NHB series offers RF power applications performance at high temperatures up to 175°C and at 500VDC. The lowest ESR (Equivalent Series Resistance) is obtained by combining highly conductive metal electrodes and proprietary 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. European Military, space grades and custom made capacitors are also available on request.
