Features:
1) Stringent dimensional tolerance allows highly reliable and high speed Automatic chip placement on PCBs
2) Terminations are plated with Ni and solder
3) High insulation resistance and high reliability
4) Used for electronic equipment
5) A variety of models including 0402, 0603, 0805 and 1206 are available
6) Use dielectric materials of COG, Y5V and X7R
COG (NPO) is the most popular formulation of the "temperature-compensation" capacitor according to EIA. It is class I dielectric materials. COG (NPO) ceramics offer very stable capacitor dielectrics. And temperature coefficient is within 0+/- 30ppm/C. Typical capacitance change with frequency and voltage is negligible at less than +/-0.05%. COG (NPO) formulations show no aging characteristics
