Answer:
GLASS CAPACITORS are used where the ultimate performance is required for RF circuits. Glass dielectric capacitors offer very high levels of performance, although their cost is high when compared to many other forms of the capacitor. Typically a glass capacitor will have a relatively low capacitance value. The values of glass capacitors may range from a fraction of a picofarad up to two to here thousand picofarads. As such these capacitors are used mainly in radio frequency circuit design.
