Ultra Hi-Q RF capacitors yield lowest ESR for high-power applications

April 29, 2016 // By Graham Prophet
Kemet's RF and microwave capacitor product portfolio is augmented with the Ultra HiQ-CBR Squared Multilayer Ceramic Capacitors, featuring a geometrically square construction resulting in lower inductance than standard EIA case sizes, thus improving low loss performance and operation at higher resonant frequencies.

Ultra HiQ-CBR Squared MLCC capacitors are suitable for high power applications such as wireless, satellite and microwave communications, RF and power amplifier modules and medical electronics.


They provide extremely low ESR under 100 pF and ultra-high Q to meet the needs of high power solutions, the comp any adds; their C0G dielectric features a robust and exceptionally stable copper electrode base metal electrode system, while the square size results in higher self-resonant frequency as compared to standard EIA case sizes.


Ultra HiQ-CBR Squared Capacitors are 250 VDC rated and are available in capacitance values up to 100 pF. Kemet is also expanding the existing HiQ-CBR product portfolio to include 200 VDC rated RF and microwave capacitors in EIA 0402 case size as well as extended capacitance offerings in EIA 0603 case size.
