Think of metal film capacitors which literally have a metal film vapor deposited onto the dielectric. The less metal thickness the less the waste in mass and bulk and metal. It only needs to be thick enough to have full conductivity. Adding thickness just adds mass and bulk with no gain, so optimal thickness is to be as thin as possible.
Chip capacitor test parameters, performance specifications, and quality conformance requirements are outlined in the EIA 198 and MIL-C-55681 specifications. We’ve put together a summary of electrical specifications for popular Class I and Class II dielectrics in Table 1. Table 1.
What does affect capacitance is the thickness of the dielectric, so the thinner the better, but it must be thick enough to block/handle the rated voltage. More metal (and dielectric) in terms of windings also increases capacitance. I am sure you have noticed that for a given voltage, more capacitance means a larger capacitor.
A parallel-plate capacitor of area A and spacing d is filled with three dielectrics as shown in Figure 5.12.2. Each occupies 1/3 of the volume. What is the capacitance of this system? [Hint: Consider an equivalent system to be three parallel capacitors, and justify this assumption.] Show that you obtain the proper limits as the dielectric constants
Figure 5.10.4 Spherical capacitor filled with dielectrics. The system can be treated as two capacitors connected in series, since the total potential difference across the capacitors is the sum of potential differences across individual capacitors. The equivalent capacitance for a spherical capacitor of inner radius 1r and outer radius r
It is defined as the ratio of the electric charge on one plate to the potential difference between the plates and measured in Farad (F). Capacitor dimensions, such as plate area and plate separation, can affect a capacitor's capacitance. Increasing plate area increases capacitance, and decreasing plate separation decreases capacitance.
