Topic:Kingtronics Multilayer Ceramic Capacitors Electrical Characteristics
Content:
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 im
