Properties of the Large-Capacitance Multilayer Ceramic Capacitor

Electrical properties of the large-capacitance multilayer ceramic capacitor made of the ceramics of Pb(Fe 2/3 W 1/3 )O 3 –Pb(Fe 1/2 Nb 1/2 )O 3 system were studied. The ceramics are sintered at 900°C in air, and therefore, it is possible to use Ag–Pd alloy as the internal electrode. The size of the...

Description
Summary:Electrical properties of the large-capacitance multilayer ceramic capacitor made of the ceramics of Pb(Fe 2/3 W 1/3 )O 3 –Pb(Fe 1/2 Nb 1/2 )O 3 system were studied. The ceramics are sintered at 900°C in air, and therefore, it is possible to use Ag–Pd alloy as the internal electrode. The size of the capacitor with capacitance of 400 µF is fairly small. Dissipation factor is extremely small (0.6%) under the D.C. voltage bias in wide frequency range. Insulation resistance is more than 6000 M Ω µF. Impedance at high frequency band is small compared with those of other electrolytic capacitors with the same capacitance. Electrical properties are hardly changed in lifetime test.
