The fundamental electrical properties of multilayer ceramic capacitors are as follows:
Polarity: Multilayer ceramic capacitors are not polar, and may be used with DC voltage applied in either direction.
Rated Voltage: This term refers to the maximum con tinuous DC working voltage permissible across the entire operating temperature range. Multilayer ceramic capacitors are not extremely sensitive to voltage, and brief applications of voltage above rated will not result in immediate failure. However, reliability will be reduced by exposure to sustained voltages above rated.
Like all other practical capacitors, multilayer ceramic capacitors also have resistance and inductance. A simplified schematic for the equivalent circuit is shown in Figure 1. Other significant electrical characteristics resulting from these additional properties are as follows:
Impedance: Since the parallel resistance (Rp) normally very high, the total impedance of the capacitor is :
The variation of a capacitor’s impedance with frequency determines its effectiveness in many applications.
Ceramic capacitors have a variety of different ceramic dielectrics as the basis of the capacitor. Ceramic dielectrics are made from a variety of forms of ceramic dielectric. The exact formulas of the different ceramics used in ceramic capacitors vary from one manufacturer to another but common compounds include titanium dioxide, strontium titanate, and barium titanate.
The actual performance of the ceramic capacitors is highly dependent upon the dielectric used. Using modern dielectrics, very high values are available, but it is also necessary to check parameters such as the temperature coefficient and tolerance. Different levels of performance are often governed by the dielectric used, and therefore it is necessary to choose the type of dielectric in the ceramic capacitor.
Kingtronics www.kingtronics.com produce and sell Ceramic Capacitors all types. Multilayer Ceramic Capacitors are available in four series in Kingtronics: AKT Series Axial Lead, Axial MLCC Capacitors(Multilayer Ceramic Capacitors), MKT Series Radial MLCC Capacitors(Multilayer Ceramic Capacitors), LKT Series Chip MLCC.
Rectifiers find a use in detection of amplitude modulated radio signals. The signal may be amplified before detection, but if un-amplified, a very low voltage drop diode must be used. When using a rectifier for demodulation the capacitor and load resistance must be carefully matched. Too low a capacitance will result in the high frequency carrier passing to the output and too high will result in the capacitor just charging and staying charged.
Kingtronics’s fast recovery rectifier diodes are very popular in the overseas market, According to the rectifier’ s application , Our Kingtronics managing ordinary rectifier diodes, ultra-fast rectifier diodes. In our Kingtronics website www.kingtronics.com ,we have detailed PDF about all kinds of diodes & rectifiers.

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
