Capacitors have frequency parameters

Capacitors with stable temperature and tight tolerance should be used in feedback loops. Bypass capacitors have less stringent requirements. Choose a capacitor with a high voltage rating to provide margin. Be aware of capacitance tolerance. Be aware of temperature coefficient. Be aware of ESL for high-frequency applications.

7.3: Common Emitter Amplifier

These capacitors will act as opens to DC creating the desired isolation. As for the AC signal, the capacitances will be chosen such that their reactances will be much smaller than the surrounding resistors at the frequency of the input. Consequently, the capacitors will appear as shorts and allow the AC signal to pass through the amplifier.

Capacitor in Electronics

A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate …
