         Demand Surges In Surface Mount Market
       Surface Mount capacitors are widely used in automotive electronics applications, mobile device applications and currently in the respiratorof the medical equipment, about the properties of capacitors, we have the following.



      Multi-layer ceramic capacitors also known as chip ceramic capacitors, different countries of the electronics industry has different names, the more commonly used name is MLCC, MLCC is mainly divided into three media capacitors, engineers will be based on the use of products, environmental requirements for MLCC selection. NPO (COG), X7R and Y5V, NPO (COG) belong to class 1 ceramics, the advantage is that there is no aging characteristics, operating temperature range of -55 degrees C to 125 degrees C, capacitance with temperature changes of 0 to 30 ppm / C, is the most stable capacitor dielectric. X7R is a class II ceramic with a high dielectric constant, the operating temperature range is -55 degrees C to 125 degrees C, the temperature change is in the range of 15%, belongs to the temperature stable ceramic, Y5V is class II ceramic, the operating temperature range is -30 degrees C to 85 degrees, Y5V has a temperature characteristic of 22% to 82% capacitance change, this advantage makes Y5V very suitable for the application of temperature in the limited temperature range. The characteristics of high-frequency resonance in small size, high pressure resistance, large capacity and bottom ESR make the use of MLCC chips cover a wide range of industrial applications.
