Multilayer ceramic capacitor (MLCC) is one of the most widely used chip components. It is a kind of chip monolith capacitor, which combines the inner electrode material and ceramic body by multilayer alternate parallel connection and burns them into a whole. It is also called chip monolith capacitor. It has the characteristics of small size, high specific capacity and high precision. It can be pasted on printed circuit board (PCB) and hybrid integrated circuit (HIC) ）Substrate can effectively reduce the volume and weight of electronic information terminal products (especially portable products) and improve the reliability of products. It conforms to the development direction of miniaturization, lightweight, high performance and multi-function of IT industry.
In the outline of the national vision and objectives for 2010, new components such as surface mount components are clearly proposed as the development focus of the electronic industry. It not only has the advantages of simple package and good sealing, but also can effectively isolate the hetero electrode. MLCC can store charge, block DC, filter, fuse, distinguish different frequency and make circuit tuning in electronic circuit. In high frequency switching power supply, computer network power supply and mobile communication equipment, organic film capacitor and electrolytic capacitor can be partially replaced, and the filtering performance and anti-interference performance of high frequency switching power supply can be greatly improved.
