New ultra Hi-Q radio frequency capacitors

KEMET is expanding its radio frequency (RF) and microwave product portfolio to now include a new series of Ultra HiQ-CBR Squared Multilayer Ceramic Capacitors. Featuring a geometrically square construction resulting in lower inductance than standard EIA case sizes, these devices improve both low loss performance and operation at higher resonant frequencies.

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

According to Mark Laps, Ceramic Specialty Technical Product Manager, “These new Ultra HiQ-CBR Squared MLCCs broaden KEMET’s RF and microwave component offerings by providing extremely low ESR under 100 pF and ultra-high Q to meet the needs of high power solutions.

“The 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 said that it would be 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.
