Applications
The Kemet CBR08C150GCGAC is designed for demanding RF and microwave circuit applications including antenna matching networks, bandpass filters, voltage-controlled oscillators, and impedance matching pads operating from VHF through microwave frequencies. Its ultra-high Q and low ESR characteristics make it especially effective in low-noise amplifier (LNA) input stages, RF power amplifier output networks, and precision tunable resonators where parasitic losses degrade system noise figure. The capacitor is also used in telecommunications base station hardware, radar front-ends, and precision test equipment requiring stable 15 pF Class I components.

Frequently Asked Questions
What makes the CBR08C150GCGAC a Class I RF capacitor and how does that classification affect circuit design?
Class I designation indicates C0G dielectric with a temperature coefficient of capacitance near 0 ppm/°C, meaning the 15 pF value varies by less than ±30 ppm across the operating temperature range. This predictable behavior simplifies filter and oscillator design by eliminating capacitance-drift compensation in RF circuits operating from -55°C to +125°C.
In a 900 MHz LNA input matching network, how does the low-ESR property of the CBR08C150GCGAC help?
At 900 MHz, even a few milliohms of ESR in a series resonant matching element directly degrades the circuit Q and increases insertion loss. The CBR08C150GCGAC ultra-high Q and low ESR design keeps resistive losses minimal, preserving the noise figure of the LNA and improving the power transfer efficiency of the 15 pF matching network.
How does the 0805 package size of the CBR08C150GCGAC compare to 0402 alternatives for RF board layout?
The 0805 package (2.0 mm x 1.25 mm footprint) offers easier hand placement and rework than 0402 parts while still fitting most RF PCB layouts at frequencies below 3 GHz. At higher frequencies above 5 GHz, the slightly larger parasitic inductance of the 0805 package may need to be accounted for in simulation, whereas 0402 parts reduce parasitic elements.
What procurement lead times and volume availability are typical for Kemet CBR series RF capacitors like the CBR08C150GCGAC?
Kemet CBR series RF capacitors are typically stocked by major distributors in quantities from 100 to over 10,000 pieces, with standard lead times of 8 to 12 weeks for factory orders when distributor stock is depleted. The CBR08C150GCGAC 15 pF value is a common catalog item suitable for both prototype quantities and production volume procurement.
