What are the key features of CBR08C150FCGAC?
- 15 pF C0G/NP0 Class I dielectric with ±1% (F-code) tolerance ensures capacitance stability within ±0.05 pF over the full operating temperature range, ideal for precision RF tuning
- Ultra-high Q factor and low ESR minimize insertion loss in resonant circuits, matching networks, and bandpass filters at frequencies up to several GHz
- 0805 SMT footprint (2.0 mm × 1.25 mm) provides a robust land pattern for RF PCBs while maintaining low parasitic inductance at high frequencies
- Class I (C0G/NP0) dielectric exhibits zero capacitance change versus DC bias and less than ±30 ppm/°C thermal drift, outperforming Class II ceramics in RF stability
What is CBR08C150FCGAC used for?
The CBR08C150FCGAC is used in RF impedance matching networks, VCO (voltage-controlled oscillator) tank circuits, and bandpass filter designs for cellular, Wi-Fi, and Bluetooth RF front-end modules where a stable, low-loss 15 pF capacitor is required to maintain resonant frequency accuracy across temperature. Its high-Q low-ESR characteristics also make it suitable for harmonic filter sections in RF power amplifiers operating at 900 MHz, 1.8 GHz, and 2.4 GHz bands, where even small increases in ESR can significantly degrade filter insertion loss and amplifier efficiency.

Frequently Asked Questions
What dielectric class does the CBR08C150FCGAC use, and how stable is its capacitance over temperature?
The CBR08C150FCGAC uses a Class I C0G (NP0) dielectric, which has a temperature coefficient of capacitance of 0 ±30 ppm/°C across the full operating temperature range of -55°C to +125°C. For a 15 pF capacitor, this translates to a maximum capacitance change of ±0.054 pF over 180°C temperature swing, making it the preferred choice over Class II X7R or X5R dielectrics that can drift ±15% and exhibit significant DC bias derating in the same 0805 package.
In which RF frequency bands can the CBR08C150FCGAC be used as a matching network element?
The CBR08C150FCGAC is rated for use in RF applications at frequencies up to several GHz. Its 15 pF value presents a reactance of approximately 10.6 Ω at 1 GHz and 5.3 Ω at 2 GHz, making it suitable as a series or shunt matching element in 50 Ω RF systems for GSM (900 MHz), LTE (700 MHz to 2.6 GHz), Wi-Fi (2.4 GHz and 5 GHz), and Bluetooth (2.4 GHz) antenna feed networks and PA output matching circuits.
How does the ±1% tolerance of CBR08C150FCGAC affect RF filter center frequency accuracy compared to ±5% alternatives?
In a bandpass filter centered at 2.4 GHz using 15 pF resonant capacitors, a ±1% (F-code) tolerance limits center frequency variation to approximately ±12 MHz due to capacitor spread, whereas ±5% (J-code) capacitors would allow ±60 MHz variation. For narrow-band Wi-Fi or Bluetooth channels spaced 5 MHz to 20 MHz apart, the ±1% CBR08C150FCGAC is necessary to keep the filter passband within specification across manufacturing tolerances without post-assembly tuning, directly improving production yield and reducing test time.
How does the ESR of CBR08C150FCGAC compare to standard multilayer ceramic capacitors and why does it matter in RF oscillators?
The CBR08C150FCGAC is specifically characterized as ultra-high Q low ESR, with ESR values typically below 0.1 Ω at 1 GHz for a 15 pF C0G capacitor in an 0805 package. In a Colpitts or Clapp VCO where the capacitor Q directly limits oscillator phase noise, substituting a standard MLCC with ESR of 0.5 Ω to 1 Ω for the CBR08C150FCGAC at 15 pF can degrade close-in phase noise by 10 dB to 20 dBc/Hz at 10 kHz offset, significantly impacting the spectral purity required for communication system local oscillator performance.
