As for capacitors, miniaturization and high capacity are the constant trend of development. Among them, multilayer ceramic capacitors are the fastest growing. Multilayer ceramic capacitors are widely used in portable products, but in recent years, technological advances in digital products have put new demands on them. For example, cell phones require higher transmission rate and higher functionality, baseband processors require high speed and low voltage, LCD modules require low thickness and high capacity capacitors. And the harshness of the steam country environment has more special requirements for multilayer ceramic capacitors: firstly, high temperature resistance, the multilayer ceramic capacitors placed in it must be able to meet the working temperature of 150 degrees, and secondly, the short circuit failure protection planning is required on the battery circuit. In other words, miniaturization, high speed and high functionality, high temperature resistance, high reliability have become the key characteristics of ceramic capacitors,x2 amperometric capacitors.
The capacity of ceramic capacitors changes with the DC bias voltage. The DC bias voltage decreases the dielectric constant, so it is necessary to reduce the dependence of the dielectric constant voltage from the material aspect and optimize the DC bias voltage characteristics. The more common in use is the X7R class multilayer ceramic capacitor, its capacity is mainly concentrated in more than 1000PF, the primary function objective of this type of capacitor is equal cross series resistance, in the high ripple current power supply decoupling, filtering and low frequency signal coupling full circuit of low power consumption performance is more prominent, safety capacitor.

Another class of multilayer ceramic capacitors is COG class, its capacity is mostly below 1000PF, the primary functional target of this class of capacitors is the loss angle tangent value. The traditional COG products with noble metal electrodes have a DF value of (2.0-8.0) X 10-4, while the COG products with innovative base metal electrodes have a DF value of (1.0-2.5) X 10-4, which is about 31-50% of the former. The low-power characteristics of these products are more obvious in GSM, CDMA, cordless phone, Bluetooth, and GPS systems that contain T/R module circuits. More often used in various high frequency circuits, such as oscillators/synchronizers, timer circuits, etc.,ceramic capacitors.
