MLCC (Multilayer Ceramic Capacitor) is a common electronic component used in signal shaping, filtering, coupling and terminal impedance matching applications in circuits. Its basic structure consists of stacks of multiple layers of ceramic sheets and metal electrodes. The ceramic layers serve as dielectrics to store energy, and the metal electrodes are used to connect circuits. Multilayer ceramic capacitors have the characteristics of high capacity density, low resistance, excellent high frequency performance and stability
At present, the global demand for chip capacitors is about 200 billion pieces. In order to meet the continuous development of electronic machines in the direction of miniaturization, large capacity, high reliability and low cost, MLCC has also developed rapidly, and its types have continued to increase. , volume continues to shrink, performance continues to improve, technology continues to advance, materials are constantly updated, and light, thin, segmented, and small series products have tended to be standardized and universal.
The market demand for MLCC continues to increase and the industrial chain continues to improve. At the same time, many manufacturers with professional technologies are also emerging. For companies with procurement needs, it is very important to get to know these manufacturers, understand the core competitiveness of their products, and choose manufacturers that can perfectly solve production needs.

It can provide fast and stable current supply for high-speed AP of mobile devices. In addition, it helps eliminate high-frequency noise and reduce the impact of external environmental stress
High Bending Strength(General)
The ductile properties of the soft termination reduce thermal/mechanical stress on the chip and resist stress caused by board bending
High Bending Strength(Automotive)
Stress management technology for external deformation is adopted to prevent MLCC defects when the PCB undergoes mechanical/thermal deformation. It offers greater durability than existing products and can be used in applications requiring safety
ESD Protection
