When placing the bypass capacitors within the matrix, try to do so only when there are existing vias available as a part of the BGA fanout pattern. Adding extra vias in these areas is possible. But be aware that extra vias will also reduce the copper channels on the internal power and ground planes due to the fanout pattern being in four
High voltage multilayer ceramic capacitors (MLCCs) are classified into two classes-those for temperature compensation (class I) and high dielectric constant materials (class II). We manufactured high voltage MLCC with temperature coefficient characteristics of C0G and X7R and studied the characteristics of electric properties. Also we studied the characteristics of

It can also vary in the same type of capacitor, depending on the dielectric material and the structure of the electrode pattern. Leaded disc ceramic capacitor 3.0 nH (0.01 µF)
In the metallization pattern above, two films have been wound to create seven capacitors in series. If each capacitor can stand 200 V, the total element can be rated as 1400 V.
