For several years, Exxelia Technologies has been conducting extensive work to miniaturize the multilayer ceramic capacitors suitable for space use. Two different methods can be used to achieve this goal: reducing the chip size or decreasing the rated voltage and also dielectric thickness (which allows a higher capacitance in a single layer and the stacking of more layers in a given chip thickness).
After the introduction of the 0603 and 16V capacitors in the QPL list, Exxelia Technologies went further in the miniaturization process, testing both methods described here. The company has performed evaluation of the following ranges:
Finally, the capacitance ranges that have been evaluated for 10V rated parts and 0402 sizes and that are now passing the qualification process will be presented.
