Ceramic Capacitors FAQ


What kind of Ceramic Capacitors do you have?

Ceramic capacitors are categorized by the shape, structure, and material / characteristics of the dielectric ceramics, as follows.

<Category by dielectric ceramics>

  Temperature Compensating Type
High Dielectric Type
Main Temperature Characteristics
C0G, U2J characteristics, etc.
X5R, X7R characteristics, etc.
Dielectric ceramics
Paraelectric titanium oxide (TiO2) or calcium zirconate (CaZrO3), etc.
Ferroelectric barium titanate (BaTiO3), etc.
The characteristics of this material are that the relative dielectric constant changes almost linearly with the temperature. The change in the capacitance value over time is negligible. Even in high temperatures, high voltages, and high frequencies, the tanδ (loss of capacitor) remains low and is excellent in stability.
Since this material provides a high relative dielectric constant from 1,000 - 20,000 at room temperature, small sizes and large capacity can be acquired.
