IHHEC
A ceramic capacitor consists of two metal electrodes (usually silver or copper) and a ceramic medium sandwiched between them. When a voltage is applied to both ends of the capacitor, a positive charge accumulates on one electrode and a negative charge accumulates on the other electrode, forming an electric field. This structure allows ceramic capacitors to store charge and release electrical energy when needed.
Capacitance value of ceramic capacitor
ϵ
ϵ is the permittivity of ceramic medium,
A
A is the electrode area,
d
d is the distance between the electrodes
Capacitance value of ceramic capacitor
C
C can be calculated by the following formula:
C=dϵA
Ceramic capacitors can be divided into two categories according to their dielectric materials
Material: Barium titanate (BaTiO₃) based material is usually used.
Class Ⅰ(Class 1)和Class Ⅱ(Class 2)。
Characteristics: Has a very stable capacitance value, almost unaffected by temperature, frequency and time. Suitable for high frequency circuit and temperature compensation circuit.
Applications: RF filters, oscillators, etc.
Material: Usually doped with barium titanate (such as BaTiO₃ doping).
Characteristics: The capacitance value varies greatly with temperature, but this property can be used to improve circuit performance in some applications. The cost is relatively low and suitable for applications requiring higher capacity density.
Applications: power filter, coupling and decoupling circuits, etc.
Application field
Ceramic capacitors are widely used in many industries because of their unique properties.
