Applications
CBR08C150F5GAC ultra-high Q RF capacitors are designed for impedance matching networks, bandpass filters, and resonant tank circuits in wireless communication equipment operating from 100 MHz to several GHz. Their low ESR and 15 pF C0G capacitance deliver minimal signal loss in LNA input matching, PA output networks, and RF antenna tuning circuits. These capacitors also serve in radar modules, satellite receivers, and test instrument RF front-ends requiring stable 15 pF / 50 V Class I ceramic capacitance.

Frequently Asked Questions
How does the ultra-high Q characteristic of CBR08C150F5GAC benefit RF impedance matching at microwave frequencies?
Ultra-high Q means very low equivalent series resistance (ESR), so CBR08C150F5GAC dissipates minimal energy in the capacitor itself at GHz frequencies. In an RF matching network operating at 2.4 GHz, high-Q 15 pF capacitors maintain insertion loss below 0.1 dB compared to standard ceramics that can add 0.3–0.5 dB, directly improving system efficiency in LNA and power amplifier matching stages.
What makes the C0G Class I dielectric of CBR08C150F5GAC suitable for precision RF filter designs?
C0G (NP0) Class I dielectric offers near-zero temperature coefficient (typically ±30 ppm/°C), so the 15 pF capacitance of CBR08C150F5GAC shifts by less than 1 fF across -55°C to +125°C. This stability maintains resonant frequency in LC bandpass filters and VCO tank circuits across the full operating temperature range without requiring calibration or trimming.
When is CBR08C150F5GAC a better choice than a standard 0805 MLCC for a 15 pF RF circuit node?
CBR08C150F5GAC is the better choice when signal insertion loss, Q factor, and capacitance accuracy all matter simultaneously — such as in a 50 Ω matched RF path at 900 MHz or higher. Standard 0805 MLCCs with X7R dielectric show capacitance variation of ±15% over temperature and lower Q, which would detune a 15 pF matching network and increase noise figure, whereas the ±1% tolerance and ultra-high Q of CBR08C150F5GAC prevent these issues.
