The insulation resistance is a value that is obtained by dividing the current flowing in the capacitor by the applied voltage. Because multilayer ceramic chip capacitors have a high insulation resistance, leak current does not present a problem in normal applications.
As many as 300 multilayer ceramic chip capacitors are used in a typical mobile phone, and more than a thousand in a PC or game console. It is fair to say that the downsizing and weight reduction of mobile devices and other electronic products would have been impossible without the miniaturization of multilayer ceramic chip capacitors.
The capacitance of a ceramic capacitor also changes according to the applied voltage. With a DC voltage, this property is referred as the DC bias characteristics.
The approximate formula for the reliability of a ceramic capacitor is: Historically for ceramic capacitors exponent X has been considered as 3. The exponent Y for temperature effects typically tends to run about 8. A capacitor is a component which is capable of storing electrical energy.
A capacitor has a capacitance of 1 farad when 1 coulomb charges it to 1 volt. One farad is a very large unit and most capacitors have values in the micro (10-6), nano (10-9) or pico (10-12) farad level. Dielectric Constant – In the formula for capacitance given above the dielectric constant of a vacuum is arbitrarily cho-sen as the number 1.
This has, in turn, placed greater demands on the capacitor terminations, especially with regard to wave-soldering and some of the more prolonged reflow techniques. Ceramic chips can easily be damaged and contaminated by poor handling or storage.

Capacitors are devices that store energy in the form of an electric field. They can also be used to filter signals of different frequencies. The capacitance value is an indicator of how much electrical charge the capacitor can hold. Multilayer ceramic capacitors consist of alternating layers of ceramic and metal.

The primary benefit of multilayer ceramic chip capacitors is their ability to provide high capacitance in small dimensions, achieved by stacking a large number of electrodes. In the early 1980s, a chip capacitor in the "3216" form factor (3.2 by 1.6 mm) had a capacitance of 0.1 µF, but that figure has reached 100 µF today—a thousand-fold increase. This matches electrolytic …
