Applications
The CBR08C150JCGAC is designed for RF and microwave circuits including bandpass filters, impedance matching networks, oscillators, and antenna coupling stages in wireless communication modules. Its ultra-high Q factor and C0G dielectric make it an ideal component for 5G infrastructure, Wi-Fi modules, and precision RF front-end designs where capacitance drift of even 1 pF at frequencies above 100 MHz can shift center frequency and degrade filter selectivity.

Frequently Asked Questions
What capacitance value and tolerance does the CBR08C150JCGAC offer for RF circuit design?
The CBR08C150JCGAC provides a 15 pF capacitance with ±5% (J-grade) tolerance. For RF applications at 2.4 GHz or 5 GHz, a 15 pF capacitor places a resonance with a 10 nH inductor near 411 MHz, and the ±5% tolerance means the effective capacitance ranges from 14.25 pF to 15.75 pF, so designers must account for this spread when simulating filter center frequency and impedance match.
Why is the C0G (Class I) dielectric critical for the CBR08C150JCGAC in high-frequency RF designs?
The C0G (NP0) Class I dielectric has a temperature coefficient of 0 ±30 ppm/°C, meaning the 15 pF capacitance changes by less than 0.45 fF per degree Celsius. In RF oscillators and bandpass filters operating at 100 MHz to several GHz, this near-zero drift prevents center frequency shifts with temperature, unlike Class II ceramics (X5R, X7R) that can exhibit 10% to 15% capacitance change over the same temperature range and destabilize RF performance.
How does the ultra-high Q and low ESR of the CBR08C150JCGAC benefit a 5G front-end filter design?
In 5G front-end filters operating at 3.5 GHz or 28 GHz bands, high Q factor (typically above 500 at 1 GHz for this series) and low ESR directly reduce insertion loss in bandpass and notch filter stages. Lower ESR means less energy is dissipated as heat per RF cycle, improving filter efficiency and reducing noise figure contributions. For a 5G small-cell design with 10 dBm transmit power, even a 0.1 dB improvement in filter insertion loss translates to measurable improvements in link budget and adjacent-channel rejection.
