Dielectric material with small dielectric loss is sandwiched by the conductive electrodes. (upper electrode・lower electrode). The dielectric material can store electricity.
Details
Dielectric material: SiO2(εr 4.2)
Capacitance: Standard specificiton: 103.4pF/mm2 (0.384μm dielectric film thickness)
Minimum dimension of dielectric: 0.1mm×0.1mm (The electrode area that determines the capacitance value is smaller than the dielectric area.)
