Capacitors are commonly formed by silicon oxide or silicon nitride dielectrics formed between metal plates and they can range in sizes from square microns to square millimeters. These elements are called Metal-Insulator-Metal (MIM) capacitors, and they can be used as discrete die components or integrated into semiconductor circuits.
A capacitor (historically known as a "condenser") is a device that stores energy in an electric field, by accumulating an internal imbalance of electric charge. It is made from two conductors separated by a dielectric (insulator).

breakdown and the electric field necessary to start the breakdown is called the dielectric strength, or breakdown strength. Thus, dielectric breakdown is a dramatic and sudden increase in the conductivity of a material due to an applied voltage. Leakage Current vs. Dielectric Current Figure 1 illustrates a simple insulation
To prevent breakdown in capacitors, it is important to choose a capacitor with a breakdown voltage higher than the expected operating voltage. It is also important to avoid applying a voltage that exceeds the capacitor''s rating. Additionally, proper circuit design and appropriate use of capacitors in the circuit can help prevent breakdown. ...

The breakdown strength of the dielectric will set an upper limit on how large of a voltage may be placed across a capacitor before it is damaged. Breakdown strength is measured in volts per unit distance, thus, the closer the plates, the less voltage the capacitor can withstand. For example, halving the plate distance doubles the capacitance ...
Farad is the unit of capacitance. A capacitor has a capacitance of 1 F when 1 coulomb (C) of electricity changes the potential between the plates by 1 volt (V). ...

Breakdown potential, also known as breakdown voltage, is the maximum voltage that a capacitor can withstand before it becomes damaged or malfunctions. It is an important factor to consider when designing and using capacitors.
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage V across their plates. The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage V across its plates. In other words, capacitance is the largest amount of …
What is capacitor breakdown? The voltage at which this occurs is called the breakdown voltage of the device, and is given by the product of the dielectric strength and the separation between the conductors, The maximum energy that can be stored safely in a capacitor is limited by the breakdown voltage.
