Suntan Ceramic Capacitor HF uses

Ceramic capacitors are suitable for moderately high-frequency work (into the high hundreds of megahertz range, or, with great care, into the low gigahertz range), as modern ceramic caps are fairly non-inductive compared to the other major classes of capacitors (film and electrolytic). Capacitor technologies with higher self-resonant frequencies tend to be expensive and esoteric (typically, mica or glass capacitors).

Sample self-resonant frequencies for one set of C0G and one set of X7R ceramic capacitors are:

  10 pF 100 pF 1 nF 10 nF 100 nF 1 µF
C0G (Class 1) 1550 MHz 460 MHz 160 MHz 55 MHz    
X7R (Class 2)     190 MHz 56 MHz 22 MHz 10 MHz
