Knowles Capacitors CF Series High Q Porcelain Capacitors

Knowles Dielectric Labs CF Series High Q Porcelain Capacitors are designed for demanding RF and high-frequency applications, providing low ESR and high Q for efficient performance. These capacitors are surface mount compatible and offer ultra-stable temperature characteristics, making them reliable across various environments. The wide capacitance range and high self-resonance ensure low noise and stability in sensitive circuits. These devices use a C0G/NP0 dielectric material with a temperature coefficient of 0±15ppm/°C, supporting an operating temperature range from -55°C to +125°C. The CF series capacitors are ideal for applications such as impedance matching, power handling, DC blocking, amplifier matching networks, filtering, and VCO frequency stabilization in RF and high-power circuits.
