Y capacitors provide a low-impedance path to ground, filtering out high-frequency noise. They are crucial for meeting regulatory standards for EMI emissions. Their unique design ensures safety through fail-open mechanisms rather than fail-short, preventing catastrophic failures.
Capacitors are available in a wide range of capacitance values, from just a few picofarads to well in excess of a farad, a range of over 10(^{12}). Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a

A capacitor is a device which stores electric charge. Capacitors vary in shape and size, but the basic configuration is two conductors carrying equal but opposite charges (Figure 5.1.1).
The *omega* is a representation of the frequency that is being applied to the circuit and the ''c'' is the measured capacitance of the capacitor. As these terms are in the denominator, we can see that if you increase either the frequency or the capacitance, the impedance of the capacitor decreases. If the frequency is 0, the impedance will be

Place the capacitor between digital and analog ground pours. Decoupling capacitors can also be used to separate analog and digital signals. In some cases, the same ground pour is used for analog and digital components. To avoid high-frequency noise being coupled from digital to ground, connect decoupling capacitors between them.

• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor. The E surface. 0 is the electric field without dielectric.
W W is the energy in joules, C C is the capacitance in farads, V V is the voltage in volts. The basic capacitor consists of two conducting plates separated by an insulator, or dielectric. This material can be air or made from a variety of different materials such as plastics and ceramics.
The simplest example of a capacitor consists of two conducting plates of area A , which are parallel to each other, and separated by a distance d, as shown in Figure 5.1.2. Experiments show that the amount of charge Q stored in a capacitor is linearly proportional to ∆ V , the electric potential difference between the plates. Thus, we may write
