简介 Brief Introduction MLCC简介： 片式多层陶瓷电容器（MLCC）是适合于表面贴装技术（SMT）的小尺寸、高比容、高精度陶瓷介质电容器，可贴装于印刷线路板（PCB）、混合集成电路（HIC）基片，有效地缩小电子信息终端产品（尤其是便携式产品）的体积和重量，提高产品可靠性。顺应了IT产业小型化、轻量化、高性能、多功能的发展方向。 General Introduction Multi-layer ceramic chip capacitor is a kind of ceramic dielectric capacitor with small size, high capacitance per volume, high accuracy, suited surface mounted technology (SMT). It is widely used in electronic circuitry, mounted printed circuit board, and hybrid IC. These different functions require specific capacitor properties. MLCC的分类：根据所采用陶瓷介质材料的类型，MLCC可划分为两大类：1类陶瓷介质MLCC具有极高的稳定性，其电容量几乎不随时间、交流信号、外加直流偏压的变化而改变，同时具有极低介质损耗，即高Q值。适用于对容量精度和应用频率要求较高的谐振电路。根据电容量的温度系数又可分为温度稳定型与温度补偿型两种。、2类陶瓷介质MLCC具有很高的比体积电容量，适合用于旁路、耦合、滤波以及对容量稳定性要求不高的鉴频电路。在DC-DC(AC)变换器和开关电源滤波电路正逐步取代钽电解电容器、铝电解电容器。 MLCC can be divided into two classes:Class 1Dielectrics are used with very high Q and linear temperature coefficient in these capacitors. They can be distinguished into temperature compensating type and temperature stable type.They can be used in such applications as oscillators and filters where low losses, low capacitance drift or temperature compensation and high stability are required.Class 2These capacitors have a very high capacitance per volume and non-linear temperature characteristics. They are used for by-passing, coupling, filter and de-coupling. For instance, they can be substituted for the Ta, Al electrolytic capacitors in DC-DC(AC) converters and switching power suppliers. MLCC的制造工艺将化学组成和微观晶相结构符合设计要求的陶瓷原粉和有机粘合剂进行充分混合成为陶瓷料浆，通过流延或喷涂等方式制得所需厚度的生坯膜片。在膜片上印刷内电极后进行叠压、切割成为单个电容器生坯后于10001400之间进行多层共烧，在所得瓷坯两端进行端电极金属化处理后即制成MLCC成品。最后经电性能测试和检验合格，即可包装入库，并交付使用。Manufacture process of MLCC Ceramic powders, which formulation and crystal phase fitted the demand of designing, are carefully mixed with solvent and binder, and then finely milled as slurry. The very thin green sheets can be obtained by casting or spraying the slurry. After this, electrode is printed on the sheets which then be stacked, pressed and cut into chips. The green chip is co-fired at temperatures between 1000 and 1400 to become a monolithic block.The final product can be formed by metalizing the termination of the compact ceramic chip. MLCC的结构MLCC的电容量与内电极交叠面积A、介质层数n和陶瓷介质材料的相对介电常数r呈正比，与单层介质厚度T呈反比关系。C = r0An / T额定工作电压主要依赖于介质材料抗电强度、介质厚度以及电容器的结构设计。如图1所示。Structure of MLCC The capacitance of a MLCC depends on the area of the electrodes (A), the thickness of the ceramic dielectric (T) and the dielectric constant of the ceramic material (r) , and the number of dielectric layers (n) with multi-layer ceramic capacitors:C = r0An / TThe rated voltage depends on the structure of the device, the thickness and strength of the dielectric Figure 1 shows the structure of a multi-layer capacitor. 结构与外形尺寸Structure & Dimension镍 Ni银/铜 Ag/Cu锡 SnCeramic DielectricElectrode陶瓷介质内电极 L2L1WHL图1 片式多层陶瓷电容器外形与内部结构Figure 1 Dimension and Cross-section of MLCC尺寸代码GB/IEC/EIA（JIS/EIAJ）长度L/mm宽度W/mm厚度（最小值/最大值）H（Min/Max）/mm端头宽度（最小值/最大值）L1（Min/Max）/mm0201（0603）0.60.030.30.030.27/0.330.10/0.200402（1005）1.00.050.50.050.45/0.550.15/0.350603（1608）1.60.100.80.100.70/0.900.20/0.600805（2012）2.00.20 1.250.200.75/1.350.25/0.75+0.30 1.25 -0.101.15/1.551206（3216）3.20.201.60.200.50/1.800.25/0.75产品型号规格及代码定义Part Number System C 0402 C0G 101 J 500 N T B产品代码Product CodeC表示片式多层陶瓷电容器MLCC尺寸规格Size Type Code（GB/IEC/EIA代码）0201；0402；0603；0805；1206；1210温度系数或温度特性T.
