KEMET's HiQ-CBR series, high frequency, high performance portfolio of RF and Microwave Capacitors in C0G dielectric feature a robust and exceptionally stable base metal electrode system that provides excellent low loss performance (high Q). These devices offer extremely low ESR and high self-resonance characteristics, and are well-suited for resonant circuit applications or those where Q and stability of capacitance are required.
Applications can include Wireless & cellular base stations, Wireless LAN & broadcast equipment, Subscriber-based wireless services, Satellite communications, RF & power amplifier modules and Medical electronics.
Features & Benefits of RF and Microwave Capacitors include C0G dielectric, Ultra-high Q, BME copper electrode system, PB-Free & RoHS compliant, Low ESR, and High thermal stability.
KEMET has expanded its radio frequency (RF) and microwave product portfolio to include a new series of Ultra HiQ-CBR Squared MLCCs.
These new devices feature 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 ideal for high power applications such as wireless, satellite and microwave communications, RF and power amplifier modules and medical electronics.
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.
